To study influences of meteorological disasters in the flowering and early fruiting stage on sugar orange industry in Guilin, meteorological disasters in the flowering and early fruiting stage and its defense measures were analyzed and studied. The flowering and early fruiting stage of sug- ar orange in Guilin is from March to June, and sudden change of temperature, thunderstorm, hale, hail, rainstorm and other natural disasters can cause the falling of large numbers of flowers and young fruit, damage of tree body, reduction of fruit in quantity, and decrease of its yield. Timely understanding information of disastrous weather and implementing management of water and fertilizer can effectively reduce the loss caused by meteorological disasters and ensue high quality and high yield of sugar orange.展开更多

The regenerated shoots at 2-4. cm from cotyledon explants on MS medium supplemented with 0.5 mg L^-1 BA and 1.0 mg L^-1IAA were excised and transferred to MS medium containing 30 g L^-1 sucrose, 8.25 g L^-1 ammonium nitrate, and 1.0 mg L^-1 BA. Following 40 d of culture, 86.2% of them flowered and set seeds. These seeds were germinable and developed into flowering plants in the fields. This study provides a simple system for rapid breeding of P. frutescens and studying the physiological mechanism of flowering of plants.展开更多

Cool temperatures were created using late planting and low light. The experiment was conducted in 2010 and 2011 using two planting dates（OPD, the optimized planting date, 25 April; LPD, the late planting date, 10 June） and two shading levels of crop relative light rate（CRLR, 100 and 60%）. Compared with fruiting position 1（FP1）, cotton yield and yield components（fiber quality, leaf sucrose and starch content, and fiber cellulose） were all decreased on FP3 under all treatments. Compared with OPD-CRLR 100%, other treatments（OPD-CRLR 60%, LPD-CRLR 100%, and LPD-CRLR 60%） had significantly decreased lint yield at both FPs of both cultivars, but especially at FP3 and in Sumian 15; this decrease was mainly caused by a large decline in boll number. All fiber quality indices decreased under late planting and shading except fiber length at FP1 with OPD-CRLR 60%, and a greater reduction was observed at FP3 and in Sumian 15. Sucrose content of the subtending leaf and fiber increased under LPD compared to OPD, whereas it decreased under CRLR 60% compared to CRLR 100%, which led to decreased fiber cellulose content. Therefore, shading primarily decreased the ＂source＂ sucrose content in the subtending leaf whereas late planting diminished translocation of sucrose towards cotton fiber. Notably, as planting date was delayed and light was decreased, more carbohydrates were distributed to leaf and bolls at FP1 than those at FP3, resulting in higher yield and better fiber quality at FP1, and a higher proportion of bolls and carbohydrates allocated at FP3 of Kemian 1 compared to that of Sumian 15. In conclusion, cotton yield and fiber quality were reduced less at FP1 compared to those at FP3 under low temperature and low light conditions. Thus, reduced cotton yield and fiber quality loss can be minimized by selecting low temperature tolerant cultivars under both low temperature and light conditions.展开更多

In this paper,correlation analysis between fruiting branch diameter of A. chinensis and fruit quality change during post-ripening period during 2013- 2015 was conducted. Results were as below:(i) correlation coefficient analysis showed that fruiting branch diameter was highly positive correlation with number of fruit ventricle,significantly positive correlation with single fruit weight when picking and the indexes after the fruit ripening single(single fruit weight,loss rate of single fruit weight,longitudinal diameter of fruit and width of fruit core),lowly positive correlation with sugar content of fruit juice,and positive correlation with thick transverse diameter of fruit after ripening.(ii) Standard errors of regression analysis between fruiting branch diameter and single fruit weight,longitudinal diameter of fruit,wide transverse diameter of fruit,thick transverse diameter of fruit,fruit core length and sugar content of fruit juice were 12. 4248,4. 2731,2. 6452,2. 0260,0. 1337 and 1. 0035 respectively; significance F values of variance analysis were 0. 0743,0. 0658,0. 1950,0. 5733,0. 2600 and 0. 1517 respectively. It showed that fruiting branch diameter had a significant difference with thick transverse diameter of fruit and insignificant differences with other indicators; quadratic curve regression equation and linear regression equation of residual curve,observed value curve,forecast value curve and normal probability curve of were analyzed,and the results were all in line with the law of quadratic curve.(iii)The larger the fruiting branch diameter,the greater the indexes after post-ripening(single fruit weight,longitudinal diameter of fruit,wide transverse diameter of fruit,thick transverse diameter of fruit and sugar content of fruit juice),the better the fruit quality. It was clear that fruiting branch diameter could be as one of important bases of fruit quality change during post-ripening period. Through investigating fruiting branch diameter and the regression equation,it could predict single fruit weight,longitudinal and transverse diameters of fruit,and sugar content of fruit juice index after the ripening.展开更多

The fruiting ability and stability of these forests are, however, decreasing because of infrequent silvicultural interventions and non-existent natural regeneration. Continuous inventories and walnut harvest measurements were carded out on 18 trial and control plots over the course of i3 year. Results showed that i） thinning had a positive influence on diameter at breast height （dbh） increase, ii） dbh growth and crown area increases are strongly and positively correlated, iii） large crowns enhanced the production of fruits, and iv） temperature conditions had a major influence on the production of fruits. The above-mentioned points are particularly relevant for young plantations but are also valid for relatively old plantations （〉 50 years）. We conclude that regular thinning substantially improves diameter growth, fruit production and ability of trees to withstand wind and snow damage in both young stands and in older walnut-fruit forests.展开更多

Molecular marker assisted selection can accelerate the breeding process by linking selection to functional genes. Methods： In a study of upland cotton （Gossypium hirsutum L.）, the F2 segregated population was constructed by crossing X1570 （short branches） with Ekangmian 13 （long branches） to identify the short fruiting branch gene and marker assisted selection with SNP（Single Nucleotide Polymorphisms, SNP） linked to its trait. Result： The result demonstrated that linked SSR marker BNL3232 was screened by BSA（Bulked segregant analysis, BSA） method; one SNP locus was found, which was totally separated from the fruiting branches trait in upland cotton. Conclusion： It was verified that this SNP marker could be used for molecular assisted selection of cotton architecture展开更多

However, such material has been produced since 2009 at the Research Institute of Horticulture in Skierniewice. To stimulate plant growth, various biopreparations were applied in an organic nursery. Apple trees （＇Topaz＇/M26） obtained from the organic nursery were used to establish an orchard in 2011. One of the combinations in the orchard consisted of trees produced in a conventional nursery. Trees whose maidens had not been fertilized at all in the organic nursery served as the control. The study was conducted for four years （2011-2014）. The least vigorously growing trees were the control trees and those that had been treated in the nursery with the preparation Tytanit, and the most vigorously--those that had been treated there with manure and the biopreparations Micosat, Humus Active ＋ Aktywit PM, and BF Quality and BF Amin. Trees whose maidens had been produced by the conventional method did not differ, in terms of growth vigour, from those treated with the biopreparations Humus UP or Vinassa. The highest cumulative fruit yields from the four-year-old trees were obtained in the combinations where the maidens had been treated in the nursery with the biopreparations BF Amin and BF Quality. The type of fertilization applied to maiden trees in the nursery had no significant effect on mean fruit weight, but it influenced the distribution of fruit in size classes.展开更多

The elevation of the plots ranged between 170 and 1200 m a.s.l. Seed fall phenology showed annual periodicity in all five plots. This was clear when assessed by the number of species but became less clear when assessed by the biomass of seed litter. Community-level annual periodicity was based on the prevalence of population-level annual periodicity and interspecific synchronization of the fruiting peak from autumn to winter. Fleshy fruits had peaks of seed fall in a wider range of months than non-fleshy fruits, since it is sometimes beneficial to bear fruit outside the community-level fruiting peaks in order to avoid interspecific competition for animal seed dispersers. No consistent effect of climatic factors on seed fall phenology was detected.展开更多

Nevertheless, very little is known about the neuroprotective potential of indicaxanthin. This study investigated the impact of indicaxanthin on neuronal damage and gut microbiota dysbiosis induced by a high-fat diet in mice. The mice were divided into three groups according to different diets: the negative control group was fed a standard diet;the high-fat diet group was fed a high-fat diet;and the high-fat diet + indicaxanthin group was fed a high-fat diet and received indicaxanthin orally(0.86 mg/kg per day) for 4 weeks. Brain apoptosis, redox status, inflammation, and the gut microbiota composition were compared among the different animal groups. The results demonstrated that indicaxanthin treatment reduced neuronal apoptosis by downregulating the expression of proapoptotic genes and increasing the expression of antiapoptotic genes. Indicaxanthin also markedly decreased the expression of neuroinflammatory proteins and genes and inhibited high-fat diet–induced neuronal oxidative stress by reducing reactive oxygen and nitrogen species, malondialdehyde, and nitric oxide levels. In addition, indicaxanthin treatment improved the microflora composition by increasing the abundance of healthy bacterial genera, known as producers of short-chain fatty acids(Lachnospiraceae, Alloprovetella, and Lactobacillus), and by reducing bacteria related to unhealthy profiles(Blautia, Faecalibaculum, Romboutsia and Bilophila). In conclusion, indicaxanthin has a positive effect on high-fat diet–induced neuronal damage and on the gut microbiota composition in obese mice.展开更多

文摘Two cotton（Gossypium hirsutum L.） cultivars, Kemian 1（cool temperature-tolerant） and Sumian 15（cool temperaturesensitive） were used to study the effects of cool temperature on carbohydrates, yield, and fiber quality in cotton bolls located at different fruiting positions（FP）. Cool temperatures were created using late planting and low light. The experiment was conducted in 2010 and 2011 using two planting dates（OPD, the optimized planting date, 25 April; LPD, the late planting date, 10 June） and two shading levels of crop relative light rate（CRLR, 100 and 60%）. Compared with fruiting position 1（FP1）, cotton yield and yield components（fiber quality, leaf sucrose and starch content, and fiber cellulose） were all decreased on FP3 under all treatments. Compared with OPD-CRLR 100%, other treatments（OPD-CRLR 60%, LPD-CRLR 100%, and LPD-CRLR 60%） had significantly decreased lint yield at both FPs of both cultivars, but especially at FP3 and in Sumian 15; this decrease was mainly caused by a large decline in boll number. All fiber quality indices decreased under late planting and shading except fiber length at FP1 with OPD-CRLR 60%, and a greater reduction was observed at FP3 and in Sumian 15. Sucrose content of the subtending leaf and fiber increased under LPD compared to OPD, whereas it decreased under CRLR 60% compared to CRLR 100%, which led to decreased fiber cellulose content. Therefore, shading primarily decreased the ＂source＂ sucrose content in the subtending leaf whereas late planting diminished translocation of sucrose towards cotton fiber. Notably, as planting date was delayed and light was decreased, more carbohydrates were distributed to leaf and bolls at FP1 than those at FP3, resulting in higher yield and better fiber quality at FP1, and a higher proportion of bolls and carbohydrates allocated at FP3 of Kemian 1 compared to that of Sumian 15. In conclusion, cotton yield and fiber quality were reduced less at FP1 compared to those at FP3 under low temperature and low light conditions. Thus, reduced cotton yield and fiber quality loss can be minimized by selecting low temperature tolerant cultivars under both low temperature and light conditions.

文摘The walnut-fruit forests （Juglans regia L.） in southern Kyrgyzstan are considered to be biodiversity hotspots and of considerable economic and ecological importance to local populations. The fruiting ability and stability of these forests are, however, decreasing because of infrequent silvicultural interventions and non-existent natural regeneration. Continuous inventories and walnut harvest measurements were carded out on 18 trial and control plots over the course of i3 year.

The above-mentioned points are particularly relevant for young plantations but are also valid for relatively old plantations （〉 50 years）. We conclude that regular thinning substantially improves diameter growth, fruit production and ability of trees to withstand wind and snow damage in both young stands and in older walnut-fruit forests.

文摘Nitrogen deficiency is a major factor that affects the yield and quality of horticultural crops.Differentially expressed proteins were identified in cucumber fruit under nitrogen deficiency treatment,and are expected to be highly useful for dissecting carbon,nitrogen and ascorbate metabolism in cucumber and for improving nitrogen fertilizer utilization.Cucumber plants grown hydroponically in Hoagland solution were transferred to nitrogen-free conditions for 3 or 5 d after the blossom of female flowers.Fruit proteome profiles were assessed using twodimensional electrophoresis.The relative expression of the genes encoding 50 selected differentially expressed proteins and 4 key enzymes in carbon metabolism was analyzed by qRT-PCR.Resulted showed that most of the identified differentially expressed proteins were mainly associated with carbon metabolism,amino acid biosynthesis,ascorbate metabolism,and proteasomes.Glucose phosphorylation was enhanced,while the pentose phosphate pathway was inhibited.Carbon metabolism and the synthesis of most amino acids was affected significantly,and ascorbate might be accumulated under nitrogen deficiency in cucumber fruit.

文摘Background： With the rapid development of genomics, many functional genes have been targeted. Molecular marker assisted selection can accelerate the breeding process by linking selection to functional genes. Methods： In a study of upland cotton （Gossypium hirsutum L.）, the F2 segregated population was constructed by crossing X1570 （short branches） with Ekangmian 13 （long branches） to identify the short fruiting branch gene and marker assisted selection with SNP（Single Nucleotide Polymorphisms, SNP） linked to its trait. Result： The result demonstrated that linked SSR marker BNL3232 was screened by BSA（Bulked segregant analysis, BSA） method; one SNP locus was found, which was totally separated from the fruiting branches trait in upland cotton. Conclusion： It was verified that this SNP marker could be used for molecular assisted selection of cotton architecture
文摘There is a deficiency of nurseries in the world producing fruit trees using the organic material management. However, such material has been produced since 2009 at the Research Institute of Horticulture in Skierniewice. To stimulate plant growth, various biopreparations were applied in an organic nursery. Apple trees （＇Topaz＇/M26） obtained from the organic nursery were used to establish an orchard in 2011. One of the combinations in the orchard consisted of trees produced in a conventional nursery. Trees whose maidens had not been fertilized at all in the organic nursery served as the control. The study was conducted for four years （2011-2014）. The least vigorously growing trees were the control trees and those that had been treated in the nursery with the preparation Tytanit, and the most vigorously--those that had been treated there with manure and the biopreparations Micosat, Humus Active ＋ Aktywit PM, and BF Quality and BF Amin. Trees whose maidens had been produced by the conventional method did not differ, in terms of growth vigour, from those treated with the biopreparations Humus UP or Vinassa. The highest cumulative fruit yields from the four-year-old trees were obtained in the combinations where the maidens had been treated in the nursery with the biopreparations BF Amin and BF Quality. The type of fertilization applied to maiden trees in the nursery had no significant effect on mean fruit weight, but it influenced the distribution of fruit in size classes.

文摘Fruiting phenology, assessed by seed fall, in five warm- and cool-temperate forests on Yakushima Island, southern Japan, was studied for two years in one 50 m × 50 m plot and for four years in four 100 m ×50 m plots. The elevation of the plots ranged between 170 and 1200 m a.s.l. Seed fall phenology showed annual periodicity in all five plots. This was clear when assessed by the number of species but became less clear when assessed by the biomass of seed litter. Community-level annual periodicity was based on the prevalence of population-level annual periodicity and interspecific synchronization of the fruiting peak from autumn to winter. Fleshy fruits had peaks of seed fall in a wider range of months than non-fleshy fruits, since it is sometimes beneficial to bear fruit outside the community-level fruiting peaks in order to avoid interspecific competition for animal seed dispersers. No consistent effect of climatic factors on seed fall phenology was detected.

文摘Aims The hypothesis of predator satiation has been proposed to explain mast fruiting in various flowering plants.it considers that the simultaneous production of large numbers of seeds by a plant population reduces the risk of seed predation for each individual.orchids produce huge numbers of seeds per fruit and rarely experience seed predation.it remains unclear which factors may affect fluctuating fruit production in orchids,which generally suffer a widespread pol-len limitation.To explore the temporal pattern of fruiting and poten-tial factors related to fluctuation in fruit production,we investigated reproductive success of a long-spurred orchid(Habenaria glaucifo-lia)in an alpine meadow with thousands of individuals over 8 years.Methods To estimate reproductive success,pollinator observation was con-ducted by day and at night,and pollinia removal and receipt were recorded in the field population for 8 years.To examine whether fruit set and seed set are pollen limited,we conducted supple-mentary pollination experiments and compared fruit set,seed set and pollinia movement of open-pollinated flowers from 2011 to 2013.We measured lengths of spurs and pollinator probos-cises,and nectar volume and concentration,to identify potential pollinators.Important Findings Hawkmoths were seen to be effective pollinators for H.glauci-folia in 3 years,whereas in the remaining 5 years no pollinators were observed,and consequently pollinia were rarely transferred.Numerous pollinia movements were observed in 2012,2013 and 2014(pollinia removal:48,59 and 85%;pollinia receipt 51,70 and 80%),and correspondingly fruit set was significantly higher in 2012 and 2013(59 and 46%)than in 2011(25%).it was fruit set,rather than seed set,that was pollen limited in this orchid in the 3 years,in that supplementary pollination increased fruit set but did not increase seed set per fruit compared to natural.Three species of hawkmoths had proboscis lengths that matched the spur length of H.glaucifolia.Fruit set in this long spurred orchid depends on the activity of long-tongued hawkmoths,resulting in significant tempo-ral variation in fruit production.mast fruiting in this alpine orchid could be attributed to a‘sit and wait’strategy,awaiting an abun-dance of effective pollinators.

文摘Climate change affects various facets of life but there is little data on its effects on wild mushroom fruiting.Yunnan Province in China is a rich source of wild mushrooms and has experienced a temperature rise over recent decades.This has resulted in warmer temperatures but the impacts of these changes on mushroom production lack documentation.We collected data on the fruiting of the highly prized matsutake mushroom(Tricholoma matsutake)in West Yunnan,China over an 11 year period from 2000 to 2010.Fruiting phenology and productivity were compared against the driving meteorological variables using Projection to Latent Structure regression.The mushrooms appeared later in the season during the observation period,which is most likely explained by rising temperatures and reduced rain during May and June.High temperature and abundant rain in August resulted in good productivity.The climate response of matsutake production results from a sequence of processes that are possibly linked with regulatory signals and resource availability.To advance the knowledge of this complex system,a holistic research approach integrating biology,ecology,genetics,physiology,and phytochemistry is needed.Our results contribute to a general model of fungal ecology,which can be used to predict the responses of fungi to global climate change.

文摘Leaves are the main photosynthesis organ that directly determines crop yield and biomass.Dissecting the regulatory mechanism of leaf development is crucial for food security and ecosystem turn-over.Here,we identified the novel function of R2R3-MYB transcription factors CsRAXs in regulating cucumber leaf size and fruiting ability.Csrax5 single mutant exhibited enlarged leaf size and stem diameter,and Csrax1/2/5 triple mutant displayed further enlargement phenotype.Overexpression of CsRAX1 or CsRAX5 gave rise to smaller leaf and thinner stem.The fruiting ability of Csrax1/2/5 plants was significantly enhanced,while that of CsRAX5 overexpression lines was greatly weakened.Similarly,cell number and free auxin level were elevated in mutant plants while decreased in overexpression lines.Biochemical data indicated that CsRAX1/5 directly promoted the expression of auxin glucosyltransferase gene CsUGT74E2.Therefore,our data suggested that CsRAXs function as repressors for leaf size development by promoting auxin glycosylation to decrease free auxin level and cell division in cucumber.Our findings provide new gene targets for cucumber breeding with increased leaf size and crop yield.

文摘Coconut(Cocos nucifera L.),a major oil and fruit crop of the Arecaceae family,is extensively cultivated across the Asia—Pacific region.Despite its agricultural importance,genome assembly in coconut remains challenging due to its large genome size and high proportion of repetitive sequences.Allele-specific expression(ASE)plays a key role in regulating plant development and evolution,yet research on ASE in coconut is limited(Shao et al.,2019;Li et al.,2021;Zhang et al.,2021;Hu et al.,2022).Among phenotypic traits,fruit color is especially important as an indicator of maturity,guiding harvest timing and post-harvest processes(Kapoor et al.,2022).While prior studies have explored various coconut traits such as salt tolerance,fiber content,and plant height(Wang et al.,2021;Yang et al.,2021),investigations into ASE and fruit color remain scarce.

文摘In this study,an automated multimodal system for detecting,classifying,and dating fruit was developed using a two-stage YOLOv11 pipeline.In the first stage,the YOLOv11 detection model locates individual date fruits in real time by drawing bounding boxes around them.These bounding boxes are subsequently passed to a YOLOv11 classification model,which analyzes cropped images and assigns class labels.An additional counting module automatically tallies the detected fruits,offering a near-instantaneous estimation of quantity.The experimental results suggest high precision and recall for detection,high classification accuracy(across 15 classes),and near-perfect counting in real time.This paper presents a multi-stage pipeline for date fruit detection,classification,and automated counting,employing YOLOv11-based models to achieve high accuracy while maintaining real-time throughput.The results demonstrated that the detection precision exceeded 90%,the classification accuracy approached 92%,and the counting module correlated closely with the manual tallies.These findings confirm the potential of reducing manual labour and enhancing operational efficiency in post-harvesting processes.Future studies will include dataset expansion,user-centric interfaces,and integration with harvesting robotics.

文摘Ascorbate(Asc),commonly known as vitamin C,is a vital molecule for plant growth,development,and stress resilience.It is also known to play a crucial role in various physiological processes,including photosynthesis,cell division,and differentiation.This article thoroughly explores the processes governing the metabolism of Asc in plants and its roles in physiological functions.It lays down a robust theoretical groundwork for delving into Asc production,transportation,functions,and its potential applications in stress alleviation and horticulture.Furthermore,recent studies indicate that Asc plays a role in regulating fruit development and affecting postharvest storage characteristics,thereby influencing fruit ripening and resilience to stress.Hence,there is a growing importance in studying the synthesis and utilization of Asc in plants.Although the critical role of Asc in controlling plant redox signals has been extensively studied,the precise mechanisms by which it manages cellular redox homeostasis to maintain the equilibrium between reactive oxygen scavenging and cell redox signaling remain elusive.This gap in knowledge presents fresh opportunities to explore how the production of Asc in plants is regulated and how plants react to environmental stressors.Furthermore,this article delves into the potential for a comprehensive investigation into the essential function of Asc in fruits,the development of Asc-rich fruits,and the enhancement of postharvest storage properties.

文摘Anthocyanins play a crucial role in shaping the visual appeal and nutritional quality of fruits.Previous research on anthocyanin biosynthesis in sweet cherry(Prunus avium L.)has primarily relied on single-omics approaches or focused on a limited range of metabolites,leaving the regulatory mechanisms and dynamic metabolism of anthocyanins during ripening inadequately characterized.This study integrated anthocyanin-targeted metabolomics and transcriptomics to identify key anthocyanins in sweet cherry and construct a transcriptional regulatory network for anthocyanin biosynthesis.A novel bHLH transcription factor,Prunus avium bHLH transcription factor 102(PavbHLH102),was identified,and its role in regulating cyanidin levels was validated through overexpression and silencing experiments.Both in vitro and in vivo assays demonstrated that PavbHLH102 activates key anthocyanin biosynthetic genes,including PavF3H,PavDFR,and PavUFGT,thereby enhancing fruit coloration.Notably,PavF3′H upregulation significantly increased cyanidin accumulation.This study provides new insights into anthocyanin regulation in sweet cherry and offers valuable resources for improving fruit quality.
文摘The cultivation of Soledad pepper(Capsicum annuum L.)is essential in Oaxaca and Veracruz,but it faces issues with pests and diseases,which affect yield and cause economic losses.To mitigate these impacts,farmers have started using biostimulants such as chitosan and plant growth promoting bacteria instead of agrochemicals due to their environmental and health benefits.This study evaluated the effect of Bacillus subtilis and chitosan,both individually and combined,on the growth,yield,and fruit quality of Soledad pepper under greenhouse conditions.Four treatments were applied at different stages of the crop cycle:Q(Chitosan),BS(Bacillus subtilis),Q+BS(Chitosan+Bacillus subtilis),and T(Control).The results showed that the combination of chitosan and Bacillus subtilis significantly improved plant growth,especially in height and stem diameter.The chitosan treatment produced the highest number of fruits and plant weight,while the combination of chitosan and Bacillus subtilis enhanced fruit quality,increasing characteristics such as size,weight,pericarp thickness,and physicochemical parameters,notably in brix degrees,citric acid percentage,and pH,outperforming the individual treatments and the control.

文摘The stability of fruit juice has consistently been an important concern in the food processing industry,which can be time-consuming and costly.Therefore,developing accurate stability early-warning model may serve as a viable solution.Based on multiple light scattering technology,this paper collects the stability data as the training set of Triphala fruit juice over a three-month period and finds that the sediment amount reached 0.6 mg/mL,composed of ellagic acid and phlobaphene,with the solution's light transmittance fluctuating range(23%-76%)and the particle size(0.27-0.29μm)on day 75.The early warning model comprises a synergistic integration of long short-term memory and backpropagation neural network models.The model exhibits a mean absolute percentage error of 0.626%,an R^(2) of 0.911,and an accuracy of 85.71%.This model is capable of predicting key stability parameters,including sedimentation,transmittance,particle size,particle migration rate,and stability index,within a 90-day period in just 7 days,and thereby provide accurate early-stage stability alerts.

文摘Indicaxanthin is a betalain that is abundant in Opuntia ficus-indica orange fruit and has antioxidative and anti-inflammatory effects. Nevertheless, very little is known about the neuroprotective potential of indicaxanthin. This study investigated the impact of indicaxanthin on neuronal damage and gut microbiota dysbiosis induced by a high-fat diet in mice. The mice were divided into three groups according to different diets: the negative control group was fed a standard diet;the high-fat diet group was fed a high-fat diet;and the high-fat diet + indicaxanthin group was fed a high-fat diet and received indicaxanthin orally(0.86 mg/kg per day) for 4 weeks. Brain apoptosis, redox status, inflammation, and the gut microbiota composition were compared among the different animal groups. The results demonstrated that indicaxanthin treatment reduced neuronal apoptosis by downregulating the expression of proapoptotic genes and increasing the expression of antiapoptotic genes. Indicaxanthin also markedly decreased the expression of neuroinflammatory proteins and genes and inhibited high-fat diet–induced neuronal oxidative stress by reducing reactive oxygen and nitrogen species, malondialdehyde, and nitric oxide levels. In addition, indicaxanthin treatment improved the microflora composition by increasing the abundance of healthy bacterial genera, known as producers of short-chain fatty acids(Lachnospiraceae, Alloprovetella, and Lactobacillus), and by reducing bacteria related to unhealthy profiles(Blautia, Faecalibaculum, Romboutsia and Bilophila). In conclusion, indicaxanthin has a positive effect on high-fat diet–induced neuronal damage and on the gut microbiota composition in obese mice.
