Pre-harvest sprouting(PHS)describes the germination of physiologically mature grains in spikes prior to harvest in cereal crops.PHS could seriously decrease grain yield and quality,which makes it a major constraint to cereal production worldwide.A number of PHS-associated genes in cereals have been reported;however,the molecular mechanisms underlying PHS remain largely elusive.Here,we report a CRISPRCas9 mutant with severe PHS in a paddy field.The mutated gene OsMFT2 encodes a phosphatidylethanolamine-binding protein(PEBP).Intriguingly,the OsMFT1,in the same PEBP family,had the opposite effect in controlling rice PHS as does OsMFT2.Germination tests of seeds of chimeric protein-expressing plants revealed that the fourth exon conferred the antagonistic activity of OsMFT1 and OsMFT2 in rice PHS.Additionally,two lines of these plants showed elevated grain numbers per panicle,implying that chimeric protein has potential to significantly increase yield.Moreover,transcriptome analysis and genetic studies indicated that OsMFT1 and OsMFT2 performed opposing functions in rice PHS owing to three co-regulated genes that being contrastingly affected by OsMFT1 and OsMFT2.Overall,it seemed that the proper combination of PEBP family members could obtain optimal PHS resistance and high yield. 展开更多

Successful polyethylene glycol fusion(PEG-fusion)of severed axons following peripheral nerve injuries for PEG-fused axons has been reported to:(1)rapidly restore electrophysiological continuity;(2)prevent distal Wallerian Degeneration and maintain their myelin sheaths;(3)promote primarily motor,voluntary behavioral recoveries as assessed by the Sciatic Functional Index;and,(4)rapidly produce correct and incorrect connections in many possible combinations that produce rapid and extensive recovery of functional peripheral nervous system/central nervous system connections and reflex(e.g.,toe twitch)or voluntary behaviors.The preceding companion paper describes sensory terminal field reo rganization following PEG-fusion repair of sciatic nerve transections or ablations;howeve r,sensory behavioral recovery has not been explicitly explored following PEG-fusion repair.In the current study,we confirmed the success of PEG-fusion surgeries according to criteria(1-3)above and more extensively investigated whether PEG-fusion enhanced mechanical nociceptive recovery following sciatic transection in male and female outbred Sprague-Dawley and inbred Lewis rats.Mechanical nociceptive responses were assessed by measuring withdrawal thresholds using von Frey filaments on the dorsal and midplantar regions of the hindpaws.Dorsal von Frey filament tests were a more reliable method than plantar von Frey filament tests to assess mechanical nociceptive sensitivity following sciatic nerve transections.Baseline withdrawal thresholds of the sciatic-mediated lateral dorsal region differed significantly across strain but not sex.Withdrawal thresholds did not change significantly from baseline in chronic Unoperated and Sham-operated rats.Following sciatic transection,all rats exhibited severe hyposensitivity to stimuli at the lateral dorsal region of the hindpaw ipsilateral to the injury.However,PEG-fused rats exhibited significantly earlier return to baseline withdrawal thresholds than Negative Control rats.Furthermore,PEG-fused rats with significantly improved Sciatic Functional Index scores at or after 4 weeks postoperatively exhibited yet-earlier von Frey filament recove ry compared with those without Sciatic Functional Index recovery,suggesting a correlation between successful PEG-fusion and both motor-dominant and sensory-dominant behavioral recoveries.This correlation was independent of the sex or strain of the rat.Furthermore,our data showed that the acceleration of von Frey filament sensory recovery to baseline was solely due to the PEG-fused sciatic nerve and not saphenous nerve collateral outgrowths.No chronic hypersensitivity developed in any rat up to 12 weeks.All these data suggest that PEG-fusion repair of transection peripheral nerve injuries co uld have important clinical benefits. 展开更多

[Objectives]This study was conducted to quickly qualitatively and quantitatively analyze the residues of 10 plant growth regulators(PGRs)in bean sprouts.[Methods]Using bean sprouts as the test material,a high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method was established to determine the residual levels of 10 PGRs in bean sprouts.[Results]Under optimized conditions,the retention time of the 10 PGRs ranged from 6.45 to 11.43 min.When the mass concentration ranged from 0.005 to 0.05μg/ml,all PGRs exhibited good linearity,with correlation coefficients(r)≥0.9991.The limits of detection(LODs,S/N=3)were in the range of 0.30-0.92μg/kg,and the limits of quantification(LOQs)were in the range of 0.50-2.10μg/kg.The average recovery values at three concentration levels ranged from 80%to 105.8%,with relative standard deviations(RSD s,n=6)of 2.8%-7.5%.[Conclusions]This method is simple and accurate,and provides technical reference for food safety monitoring. 展开更多

Glucosinolates are important phytochemicals in Brassicaceae.We investigated the effect of CaCl_(2)-HCl electrolyzed water(CHEW)on glucosinolates biosynthesis in broccoli sprouts.The results showed that CHEW treatment significantly decreased reactive oxygen species(ROS)and malondialdeh yde(MDA)contents in broccoli sprouts.On the the 8^(th)day,compared to tap water treatment,the the total glucosinolate content of broccoli sprouts with CHEW treatment increased by 10.6%and calcium content was dramatically enhanced from 14.4 mg/g DW to 22.7 mg/g DW.Comparative transcriptome and metabolome analyses revealed that CHEW treatment activated ROS and calcium signaling transduction pathways in broccoli sprouts and they interacted through MAPK cascades.Besides,CHEW treatment not only promoted the biosynthesis of amino acids,but also enhanced the expression of structural genes in glucosinolate synthesis through transcription factors(MYBs,bHLHs,WRKYs,etc.).The results of this study provided new insights into the regulatory network of glucosinolates biosynthesis in broccoli sprouts under CHEW treatment. 展开更多

Cruciferous sprout is a new form of vegetable product rich in bioactive compounds,especially glucosinolates.Previous studies have focused on increasing the accumulation of glucosinolates in cruciferous sprouts by applying different chemical regulators,with a particular focus on their contribution to nutritional quality and health benefits.Nevertheless,the effects of melatonin and UV-B irradiation on glucosinolate biosynthesis remain unclear.In this study,it was found that changes in melatonin concentrations significantly affected the contents of individual as well as total aliphatic and indolic glucosinolates.The 5μmol·L^(-1)melatonin was decided as the optimum concentration that could increase the content of beneficial glucosinolates including glucoraphanin and 4-methoxy glucobrassicin in Chinese kale sprouts.Notably,the enhancement of glucosinolate accumulation by melatonin treatment could be further amplified by UV-B irradiation.Furthermore,our results showed that R2R3-MYB transcription factor BoaMYB28 and BoaMYB51,which are central regulators of aliphatic and indolic glucosinolate biosynthesis respectively,were both involved in the regulation of glucosinolate biosynthesis by melatonin and UV-B irradiation.Additionally,the expression of glucosinolate biosynthetic genes,including BoaCYP79F1,BoaCYP83A1,BoaSUR1,BoaUGT74B1,BoaCYP79B2,BoaCYP79B3,and BoaCYP83B1 participated in the formation of core structures and BoaFMOGS-OX5,BoaAOP2,BoaCYP81F2,and BoaIGMT1 involved in the sidechain modification of aliphatic and indolic glucosinolate,was regulated by melatonin or UV-B irradiation.Taken together,these findings provide a potential strategy for improving the nutritional quality and resistance of Chinese kale sprouts. 展开更多

Tartary buckwheat(Fagopyrum tataricum)is a well-known pseudocereal for its health and economic value.However,abundant antinutritional factors(ANFs)reduces its health benefits.As reported,germination can improve the nutritional profile of grains.In this study,we systematically evaluate the safety of Tartary buckwheat seeds(TB)and Tartary buckwheat sprouts(TBS)used as high active ingredients.After evaluating nutrition levels,bioactive compounds and ANFs in TBS during germinating,5^(th)-day TBS were selected as the raw material.C57BL/6J mice were gavaged daily with distilled water,TB,or TBS for 6 weeks.The physiological indices related to ANFs were determined.Results showed that the TB intake tends to generate negative effects on the gut microbiota,and organs.Additionally,upon TB intake,the Fe^(3+)content in serum,trypsin activity in pancreas and jejunum decreased,while the cytokine,IgE,and histamine levels in serum,water content in faeces,cytokine levels in liver and jejunum increased.Conversely,TBS did not induce any obvious negative effects on the above relevant indices and showed better lipid-lowering effect.Altogether,TBS are safer and more effective as a raw material to produce the functional food for long-term consumption with the intention of preventing and treating hyperlipidaemia. 展开更多

Sprouts are ready-to-eat and are recognized worldwide as functional components of the human diet.Recent advances in innovative agricultural techniques could enable an increase in the production of healthy food.The use of light-emitting diode(LED)in indoor agricultural production could alter the biological feedback loop,increasing the functional benefits of plant foods such as wheat and lentil sprouts and promoting the bioavailability of nutrients.The effects of white(W),red(R),and blue(B)light were investigated on the growth parameters and nutritional value of wheat and lentil sprouts.In the laboratory,seeds were sown under three different LED treat-ments:white,red,and blue light,while normal incandescent light served as a control.Percentage seed germina-tion improved by 18.34%and 12.67%for wheat and 18.34%and 12.67%for lentil sprouts under LED treatments R and B,respectively.An increase in total soluble protein and sugar by 33.4%and 9.23%in wheat and by 31.5%and 5.87%in lentils was observed under the R LED treatment.Vitamin C concentrations in wheat and lentils were significantly increased by R LED compared to all other treatments.Other parameters,including potassium and sodium concentrations,were significantly increased under red and blue light compared to the control;white light,on the other hand,significantly decreased all these parameters.According to the experimental data,red and blue LED light could be beneficial in the production of functional wheat and lentil sprouts with high nutrient concentrations. 展开更多

To find out the effect of planting methods on the yield and yield attributes of short duration Aman rice varieties, a field trial was conducted at the farm of Bangladesh Rice Research Institute, Gazipur, during July to November 2012. The treatments comprised of three BRRI released high yielding varieties viz., BRRI dhan39, BRRI dhan49 and BRRI dhan57 and three planting methods viz., direct seeding of dry seed, direct seeding of sprouted seed and transplanting. It was a factorial experiment conducted in a Randomized Complete Block Design with three replications. Planting methods had a significant effect on the growth duration of rice. The rice crop established with direct seeding of the dry and sprouted seed matured 7 days earlier than transplanting. The variety BRRI dhan39 gave the highest yield (4.964 t·ha-1) when grown with direct seeding of sprouted seed compared to other varieties. The highest net return (23362.00 BDT ha-1) and cost benefit ratio (1:1.49) were observed in direct seeding of the sprouted seed method. So, direct seeding of sprouted seed might be the best planting method because about 19.94% production cost is reduced due to the omission of seedling raising and transplanting operations as well as the reduction in the length of the crop cultivation period. 展开更多

[Objective] The aim was to provide theoretical basis for the prevention and control of the invasion of Alternanthera philoxeroides(Mart.)Griseb.[Method] Effects of fragmentation intensity of fresh roots and their burial depth on sprouting and early growth of A.philoxeroides were studied by control test.[Result] More sprouts of A.philoxeroides emerged when the fragmentation intensity of fresh roots was higher,while if the fragmentation intensity of fresh roots was lower,the early growth of A.philoxeroides was more rapid.The soil buried depth had significant effect on fresh root sprouts' emergence,but once fresh root sprouts could reach the soil surface and were given enough growth time,even if the fresh roots were buried in different depths,soil buried depth had no significant effect on its young plant growth.[Conclusion] If different fragmentation intensities of fresh roots present,there is a kind of trade-off strategy between root sprouts' emergence and plant' early growth,by which A.philoxeroides can invade new habitat successfully.To control the invasion of A.philoxeroides,it is critical to prevent its fresh root sprouts from emerging to soil surface,that is,to bury the fresh roots at a further soil depth. 展开更多

Objective: To investigate the change in total phenolic compounds, antioxidant activity,and resveratrol content of five different germinated peanut cultivars.Methods: The germinated sprouts of five peanut cultivars(Kalasin1, Kalasin2, Konkaen,Konkaen4, and Tainan9) were extracted with 80% ethanol and collected as crude extract.The antioxidant capacities were determined with 2,2-diphenyl-1-picrylhydrazyl and ferric ion reducing antioxidant power method.The total phenolic compound was measured using the Folin–Ciocalteau assay.The qualification and quantification of resveratrol was performed by high performance liquid chromatography method.Results: Among the five cultivars, a three-day germination of Kalasin1 showed the highest phenolic content [(40.67 ± 2.62) mg gallic acid/g dry weight], expressed the highest 2,2-diphenyl-1-picrylhydrazyl antioxidant value [(80.51 ± 1.47) mmol/L Trolox/g dry weight], and ferric ion reducing antioxidant power antioxidant value [(171.33 ± 8.59)mmol/L ascorbic acid/g dry weight].However, the high performance liquid chromatography result of Kalasin2 significantly increased to the highest resveratrol content of(6.44 ± 1.26) mg/g dry weight on the second day of germination.Conclusions: The variation of phytochemical content in the peanut sprout is due to the effect of the peanut cultivar and the germination period. 展开更多

Pre-harvest sprouting(PHS)is a disadvantageous trait in cereal production worldwide,causing large economic losses each year.Its regulation mechanism is still unclear.We generated the Oryza sativa Viviparous1(OsVP1)mutant using gene editing technique,which shows increased PHS compared with that of the wild type Nipponbare.OsVP1 is localized mainly in the nucleus and expressed in various tissues and organs.Expression of Seed dormancy 4(Sdr4),a key gene controlling PHS,was sharply reduced in OsVP1 mutants.OsVP1 bound to the specific motif CACCTG in the promoter of Sdr4 and activated its expression in rice protoplasts.Overexpression of Sdr4 reduced the high seed germination rate of OsVP1 mutant cr-osvp1-1,showing that Sdr4 acts as a downstream target of OsVP1.Both OsVP1 and Sdr4 loss-of-function mutants were insensitive to exogenous ABA and employed the ABA signaling pathway in regulating seed dormancy.These findings shed light on the control of seed dormancy aimed at preventing PHS in rice. 展开更多

Both sensorimotor and autonomic dysfunctions often occur after spinal cord injury(SCI). Particularly, a high thoracic or cervical SCI interrupts supraspinal vasomotor pathways and results in disordered hemodynamics due to deregulated sympathetic outflow. As a result of the reduced sympathetic activity, patients with SCI may experience hypotension, cardiac dysrhythmias, and hypothermia post-injury. In the chronic phase, changes within the CNS and blood vessels lead to orthostatic hypotension and life-threatening autonomic dysreflexia(AD). AD is characterized by an episodic, massive sympathetic discharge that causes severe hypertension associated with bradycardia. The syndrome is often triggered by unpleasant visceral or sensory stimuli below the injury level. Currently the only treatments are palliative - once a stimulus elicits AD, pharmacological vasodilators are administered to help reduce the spike in arterial blood pressure. However, a more effective means would be to mitigate AD development by attenuating contributing mechanisms, such as the reorganization of intraspinal circuits below the level of injury. A better understanding of the neuropathophysiology underlying cardiovascular dysfunction after SCI is essential to better develop novel therapeutic approaches to restore hemodynamic performance. 展开更多

Axonal regeneration and ifber regrowth is limited in the adult central nervous system, but re-search over the last decades has revealed a high intrinsic capacity of brain and spinal cord circuits to adapt and reorganize after smaller injuries or denervation. Short-distance ifber growth and synaptic rewiring was found in cortex, brain stem and spinal cord and could be associated with restoration of sensorimotor functions that were impaired by the injury. Such processes of struc-tural plasticity were initially observed in the corticospinal system following spinal cord injury or stroke, but recent studies showed an equally high potential for structural and functional reorganization in reticulospinal, rubrospinal or propriospinal projections. Here we review the lesion-induced plastic changes in the propriospinal pathways, and we argue that they represent a key mechanism triggering sensorimotor recovery upon incomplete spinal cord injury. The for-mation or strengthening of spinal detour pathways bypassing supraspinal commands around the lesion site to the denervated spinal cord were identiifed as prominent neural substrate inducing substantial motor recovery in different species from mice to primates. Indications for the exis-tence of propriospinal bypasses were also found in humans after cortical stroke. It is mandatory for current research to dissect the biological mechanisms underlying spinal circuit remodeling and to investigate how these processes can be stimulated in an optimal way by therapeutic inter-ventions (e.g., ifber-growth enhancing interventions, rehabilitation). This knowledge will clear the way for the development of novel strategies targeting the remarkable plastic potential of pro-priospinal circuits to maximize functional recovery after spinal cord injury. 展开更多

To determine the growth strategies during early regeneration stages of two major coniferous species (Pinus massoniana and Cunninghamia lanceolata) in a secondary mixed coniferous forest in the Huangshan region of Anhui Province, eastern China, we examined height growth, diameter-height relationship and the relationship between main stem and lateral branch elongation in saplings, with a particular focus on the effects of light intensity and regeneration mode (seedlings versus sprouts). When light intensity was sufficiently high, the extension growth of main stems was greater and more positively related to initial size for P. massoniana than for C. lanceolata. The slenderness of the stem form increased in the following order: C. lanceolata seedlings 〈 P. massoniana seedlings 〈 C. lanceolata sprouts. P. massoniana became less slender with increasing light intensity. P. massoniana had shorter branches than C. lanceolata given the same main stem elongation. Growth allocation depended more strongly on light intensity for P. massoniana than for C. lanceolata, with more growth allocated to the main stem under dark conditions. These results suggest that P. massoniana is a typical shade avoider; this species gives priority to extension growth of the main stem, especially when it is shaded. In contrast, C. lanceolata is a shade tolerator; this species allocates more biomass to radial growth of its main stems and to extension growth of branches. Based on these results, the ecological characteristics of P. massoniana and C. lanceolata and the roles of seedlings and sprouts are discussed in relation to stand dynamics of the mixed forests of P. massoniana and C. lanceolata in eastern China. 展开更多

AIM: To evaluate effects of dietary supplementation of sulforaphane(SF)-rich broccoli sprout(BS) extract on hepatic abnormalities in Japanese male participants.METHODS: In a randomized,placebo-controlled,double blind trial,male participants with fatty liver received either BS capsules containing glucoraphanin [GR; a precursor of SF(n = 24)] or placebo(n = 28) for 2 mo. Liver function markers,serum levels of aspartate and alanine aminotransferases(AST and ALT,respectively) and γ-glutamyl transpeptidase(γ-GTP) and an oxidative stress marker,urinary levels of 8-hydroxydeoxyguanosine(8-OHd G),were measured and compared in participants before and after the trial period. In an animal model,chronic liver failure was induced in Sprague-Dawley rats by successive intraperitoneal injection with N-nitrosodimethylamine(NDMA) for 4 wk. Concomitantly,rats received AIN-76 diets supplemented with or without BS extract. Thereafter,rats were sacrificed,and their sera and livers were collected to measure serum liver function markers and hepatic levels of thiobarbituric acid reactive substances(TBARS) levels and hepatic glutathione S-transferase(GST) activity,a prototypical phase 2 antioxidant enzyme.RESULTS: Dietary supplementation with BS extract containing SF precursor GR for 2 mo significantly decreased serum levels of liver function markers,ALT [median(interquartile range),before: 54.0(34.5-79.0) vs after supplementation: 48.5(33.3-65.3) IU/L,P < 0.05] and γ-GTP [before: 51.5(40.8-91.3) vs after: 50.0(37.8-85.3) IU/L,P < 0.05],as well as the alkali phosphatase activity. Placebo showed no significant effects on the markers. The urinary level of 8-OHd G,an established oxidative stress marker,was significantly reduced in participants who had received BS capsules but not the placebo [before: 6.66(5.51-9.03) vs after: 5.49(4.89-6.66) ng/mg-creatinine,P < 0.05]. The reduction of urinary 8-OHd G was significantly correlated with decreased levels of both ALT and γ-GTP [?8-OHd G and ?ALT: Spearman r(r) 0.514 and P = 0.012,?8-OHd G and ?γ-GTP: r = 0.496 and P = 0.016]. Intake of BS extract prevented NDMA-induced chronic liver failure in rats,which was attributable to the suppression of the increase in TBARS through induction of hepatic phase 2 antioxidant enzymes including hepatic GST(86.6 ± 95.2 vs 107.8 ± 7.7 IU/g,P < 0.01).CONCLUSION: Dietary supplementation with BS extract containing the SF precursor GR is likely to be highly effective in improving liver function through reduction of oxidative stress. 展开更多

Glucosinolates, anthocyanins, total phenols, and vitamin C, as well as antioxidant capacity, were investigated in Chinese kale sprouts treated with both glucose and gibberellic acid(GA_3). The combination of 3%(0.03 g/ml) glucose and 5 μmol/L GA_3 treatment was effective in increasing glucosinolate content while glucose or GA_3 treatment alone did not influence significantly almost all individual glucosinolates or total glucosinolates. The total phenolic content and antioxidant activity of Chinese kale sprouts were enhanced by combined treatment with glucose and GA_3, which could be useful in improving the main health-promoting compounds and antioxidant activity in Chinese kale sprouts. 展开更多
