文摘Previous observational and genomic-wide association studies(GWAS)suggested the association between several phenotypic factors and keratinocyte carcinoma,including lifestyle and dietary,photodamage-related conditions and socioeconomic status.The causal effect of these phenotypic factors in keratinocytes carcinoma etiology remains unclear.In this study,we utilized two-sample mendelian randomization analysis from multiple large-scale GWAS datasets of keratinocytes carcinoma including more than 300,000 patients.Genetic instrumental variables(IVs)were constructed by identifying single nucleotide polymorphisms(SNPs)that associate with corresponding factors.The inverse variance weighted(IVW)method and four robust MR approaches,including weighted median estimator,MR-Egger regression,simple mode and weighted mode were implemented for causal inferences and assess the sensitivity across findings.In this analysis,ease of skin tanning was identified as casual protective factor of keratinocyte carcinoma(Basal cell carcinoma:IVW OR=0.718,95%CI 0.654-0.788,p<0.001;Cutaneous squamous cell carcinoma:IVW OR=0.601,95%CI 0.516-0.701,p<0.001).Other phenotypic factors,such as coffee intake,alcohol consumption,smoking and socioeconomic status,indicated insignificant effects on keratinocyte carcinoma risk in the analysis,and therefore,our study does not support their roles in modifying keratinocytes carcinoma risks.Our extensive analysis provides strong evidence of the causative protective effect of ease of skin tanning in keratinocyte carcinoma.The findings suggest that individuals who are less prone to tanning may need to pay greater attention to sun protection in their daily activities to reduce the potential risk of keratinocyte cancers.

文摘Capturing crop physiological information by phenotyping is a key trend in smart agriculture.However,current studies underutilize spatial structural information in phenotypic imaging.To evaluate the feasibility of crop cold stress monitoring based on phenotypic spatial variability,we conducted controlled experiments on'Toyonoka'strawberry plants under four dynamic cooling gradients and three stress durations and analyzed the dependence of their photosynthetic physiology and phenotypic traits on temperature-time interactions.The results revealed that NPQ/1D-Parallel/TENT,Y(NO)/2D-Region/INEM,and qP/1D-Parallel/TENT presented the highest mutual information,with the maximum net photosynthetic rate(Pmax),relative electrolyte conductivity(REC),and total chlorophyll content(Chl_(a+b)),respectively.The difference between the Photosynthetic Physiological Potential Index(PPPI)and relative negative accumulated temperature(RNAT)/650 effectively was used to calculate the cold damage risk(CDRI).An XGBoost-based model integrating the PPPI and RNAT outperformed AdaBoost and RandomForest,achieving an R^(2) of 0.98,an RMSE of 0.337,a classification accuracy of 92.13%,and a Kappa coefficient of 0.904.qP/1D-Parallel/TENT contributed the most to the model.This study provides a scientific basis for phenotypic information mining and agro-meteorological disaster monitoring.

文摘Genotype-environment interaction(G×E)models have potential in digital breeding and crop phenotype pre-diction.Using genotype-specific parameters(GSPs)as a bridge,crop growth models can capture G×E and simulate plant growth and development processes.In this study,a dataset containing multi-environmental planting and flowering data for 169 genotypes,each with 700K single nucleotide polymorphism(SNP)markers was used.Three rice growth models(ORYZA,CERES-Rice,and RiceGrow),SNPs,and climatic indices were in-tegrated for flowering time prediction.Significant associations between GSPs and quantitative trait nucleotides(QTNs)were investigated using genome-wide association study(GWAS)methods.Several GSPs were associated with previously reported rice flowering genes,including DTH2,DTH3 and OsCOL15,demonstrating the genetic interpretability of the models.The rice models driven by SNPs-based GSPs showed a decrease in goodness of fit as reflected by increased root mean square errors(RMSE),compared to the traditional model calibration.The predictions of crop model were further modified using the machine learning(ML)methods and climate indicators.The accuracy of the modified predictions were comparable to what was achieved using the traditional calibration approach.In addition,the Multi-model ensemble(MME)was comparable to that of the best individual model.Implications of our findings can potentially facilitate molecular breeding and phenotypic prediction of rice.

文摘Identifying and segmenting the vitreous and starchy endosperm of maize kernels is essential for texture analysis.However,the complex internal structure of maize kernels presents several challenges.In CT(computed tomog-raphy)images,the pixel intensity differences between the vitreous and starchy endosperm regions in maize kernel CT images are not distinct,potentially leading to low segmentation accuracy or oversegmentation.Moreover,the blurred edges between the vitreous and starchy endosperm make segmentation difficult,often resulting in jagged segmentation outcomes.We propose a deep learning-based CT image analysis pipeline to examine the internal structure of maize seeds.First,CT images are acquired using a multislice CT scanner.To improve the efficiency of maize kernel CT imaging,a batch scanning method is used.Individual kernels are accurately segmented from batch-scanned CT images using the Canny algorithm.Second,we modify the conventional architecture for high-quality segmentation of the vitreous and starchy endosperm in maize kernels.The conventional U-Net is modified by integrating the CBAM(convolutional block attention module)mechanism in the encoder and the SE(squeeze-and-excitation attention)mechanism in the decoder,as well as by using the focal-Tversky loss function instead of the Dice loss,and the boundary smoothing term is weighted as an additional loss term,named CSFTU-Net.The experimental results show that the CSFTU-Net model significantly improves the ability of segmenting vitreous and starchy endosperm.Finally,a segmented mask-based method is proposed to extract phenotype parameters of maize kernel texture,including the volume of the kernel(V),volume of the vitreous endosperm(VV),volume of starchy endosperm(SV),and ratios over their respective total kernel volumes(W/V and SV/V).The proposed pipeline facilitates the nondestructive quantification of the internal structure of maize kernels,offering valuable insights for maize breeding and processing.

文摘Plant height(PH)is a key agronomic trait influencing plant architecture.Suitable PH values for cotton are important for lodging resistance,high planting density,and mechanized harvesting,making it crucial to elucidate the mechanisms of the genetic regulation of PH.However,traditional field PH phenotyping largely relies on manual measurements,limiting its large-scale application.In this study,a high-throughput phenotyping platform based on UAV-mounted RGB and light detection and ranging(LiDAR)was developed to efficiently and accurately obtain time series PHs of 419 cotton accessions in the field.Different strategies were used to extract PH values from two sets of sensor data,and the extracted values were used to train using linear regression and machine learning methods to obtain PH predictions.These predictions were consistent with manual measurements of the PH for the LiDAR(R^(2)=0.934)and RGB(R^(2)=0.914)data.The predicted PH values were used for GWAS analysis,and 34 PH-related genes,two of which have been demonstrated to regulate PH in cotton,namely,GhPH1 and GhUBP15,were identified.We further identified significant differences in the expression of a new gene named GhPH_UAV1 in the stems of the G.hirsutum cultivar ZM24 harvested on the 15th,35th,and 70th days after sowing compared with those from a dwarf mutant(pag1),which presented shortened stem and internode phenotypes.The overexpression of GhPH_UAV1 significantly promoted cotton stem development,whereas its knockout by CRISPR-Cas9 dramatically inhibited stem growth,suggesting that GhPH_UAV1 plays a positive regulatory role in cotton PH.This field-scale high-throughput phenotype monitoring platform significantly improves the ability to obtain high-quality phenotypic data from large populations,which helps overcome the imbalance between massive genotypic data and the shortage of field phenotypic data and facilitates the integration of genotype and phenotype research for crop improvement.

文摘Background:Plant phenomics has made significant progress recently,with new demand to move from external characterization to internal exploration through data combination.Hyperspectral and metabolomic data,with cause-and-effect relationship,are given priority for integration.However,few efficient integrating methods are available.Results:Here,we showed the way to explore hyperspectral data through combining with upper-level metabolomic data and perform higher-level-data-guided dimension reduction in target-trait-oriented manner to obtain high analysis efficiency.To verify its feasibility,two-stage pipeline combining hyperspectral and metabolic data was designed to discriminate salt-tolerant phenotype for Medicago truncatula mutants.Centered on salt tolerance,data are combined through constructing metabolite-based spectral indices outlining tolerance-related metabolic changes in primary screening,and models converting hyperspectral data to metabolite content for detailed characterizing in secondary screening.Target phenotype could be discriminated after five-day salt-treatment,much earlier than phenotypic difference appearance.20 mutants with salt-tolerant phenotype were successfully identified from about 1000 mutants,almost tripled that of unintegrated analysis.Accuracy rate,confirmed with salt-tolerance analysis for experimental verification,reached 90%,which can be optimized to 100%theoretically utilizing results from hierarchical-clustering-assisted Principal Component Analysis.Conclusions:Mutant-screening pipeline provided here is a practical example for targeted data integration and data mining under the guide of upper-layer omic data.Targeted combination of phenomic and metabolomic data provides the ability for accurate phenotype discrimination and prediction from both external and internal aspects,providing a powerful tool for phenotype selection in new-generation crop breeding.

文摘Water stress is a crucial environmental factor that impacts the growth and yield of rice.Complex field micro-climates and fluctuating water conditions pose a considerable challenge in accurately evaluating water stress.Measurement of a particular crop trait is not sufficient for accurate evaluation of the effects of complex water stress.Four comprehensive indicators were introduced in this research,including canopy chlorophyll content(CCC)and canopy equivalent water(CEW).The response of the canopy-specific traits to different types of water stress was identified through individual plant experiments.A hybrid method integrating the PROSAIL radiative transfer model and multidimensional imaging data to retrieve these traits.The synthetic dataset generated by PROSAIL was utilized as prior knowledge for developing a pre-trained machine learning model.Subsequently,reflectance separated from hyperspectral images and phenotypic indicators extracted from front-view images were innovatively united to retrieve water stress-related traits.The results demonstrated that the hybrid method exhibited improved stability and accuracy of CCC(R=0.7920,RMSE=24.971μg cm^(-2))and CEW(R=0.8250,RMSE=0.0075 cm)compared to both data-driven and physical inversion modeling methods.Overall,a robust and accurate method is proposed for assessing water stress in rice using a combination of radiative transfer modeling and multidimensional image-based data.

文摘The disease syndrome"basses richesses"(SBR)leads to a significant reduction in sugar beet biomass and sugar content,negatively affecting the sugar economy.The mechanistic understanding regarding growth and photo-assimilates distribution within the sugar beet taproot diseased with SBR is currently incomplete.We combined two tomographic methods,magnetic resonance imaging(MRI)and positron emission tomography(PET)using 11C as tracer,to non-invasively determine SBR effects on structural growth and photoassimilates distribution within the developing taproot over six weeks.MRI analysis revealed a deformed cross-sectional anatomical structure from an early stage,as well as a reduction in taproot volume and width of inner cambium ring structures of up to 26 and 24%,respectively.These SBR disease effects were also confirmed by post-harvest analysis of the taproot.PET analysis revealed a heterogeneous distribution of labeled photoassimilates for diseased plants:sectors of the taproot with characteristic SBR symptoms showed little to very low ^(11)C tracer signal.The heterogeneity of SBR disease effects is most likely due to a partial inoculation of leaves leading to an uneven distribution of the SBR pathogen in the taproot through the strong vascular interconnection between shoot and root.Also,the pathogen needs to spread non-uniformly within the taproot to explain the observed marked increase of the SBR disease effects over time.Our results indicate that SBR affects photoassimilates sink capacity at an early stage of taproot development.Co-registration of MRI and PET may support an early judging of susceptibility and selection of promising genotype candidates for future breeding programs.

文摘High-altitude polycythemia(HAPC)is a prevalent chronic condition affecting individuals at high altitudes,including both highland and plains populations.This study,involving 2248 participants,explored genetic susceptibility to HAPC among ethnic groups,with 898 HAPC patients(450 Han,448 Tibetan).The Genome-wide Association Study,encompassing 198 cases(100 Han,98 Tibetan),identified eight Tibetan HAPC-susceptibility single-nucleotide polymorphisms and four in Han individuals.The common polymorphism locus rs7618658(SNX4,pcombine<5×10^(-8))was validated in both popula-tions.The investigation of Tibetan EPAS1 revealed the rs1374749 locus,along with linked loci,as a potential prevalence factor for HAPC.The GGTAC haplotype containing this locus emerged as a Protect haplotype for HAPC(p=2.461×10^(-12),OR=0.344).Enrichment analysis revealed that Tibetans exhibited susceptibility in oxygen-sensing pathways,such as EPAS1,associated with phenotypes like hemoglobin and platelets.In contrast,Han Chinese showed significant sensitivity in cell differentiation and angiogenesis,closely linked to hemoglobin,hematocrit,and platelets.

文摘Location-based methods for counting rice panicles have often been underestimated,primarily due to their perceived inferior performance when compared to detection-based techniques.However,we argue that the po-tential of these location-based methods has not been fully realized,largely owing to the limitations of existing model architectures.In response to this challenge,we introduce LKNet,an innovative model developed on the foundation of the location-based framework P2Pnet.To enhance the performance of panicle counting across diverse types and growth stages,we implemented several key strategies.Firstly,we reconstructed the localization loss function as a predictive probability distribution to reduce the influence of manual labeling.Additionally,we dynamically adapted the receptive field to better accommodate different panicle types through the use of large kernel convolutional blocks.We evaluated LKNet on several publicly available counting task datasets and ach-ieved state-of-the-art performance on the Diverse Rice Panicle Detection dataset.Furthermore,we employed a rice panicle dataset collected at an altitude of 7 m,which includes various panicle types and growth stages for model training and evaluation.The results showed that LKNet effectively accommodates variations in panicle morphology,with R^(2) values ranging from 0.903 to 0.989.These findings highlight LKNet's potential to enhance precision in panicle counting in rice breeding programs.

文摘Ensuring food security has become a global challenge owing to climate change and population growth.High-throughput phenotyping can effectively drive crop genetic enhancement,which can potentially solve food crisis.Phenotyping robot is an essential part of crop ground phenotyping information monitoring,although there are challenges such as the inability to adjust the fixed track width,poor load capacity of the detection robotic arm,and inability to fuse information in real-time.This study reports a phenotyping robot with a gantry-style chassis featuring an adjustable wheeltrack(1400-1600 mm)to adapt to different row spacing arrangements and reduced damage,and function effectively in both dry field and paddy field environments.A six-degree-of-freedom sensor gimbal with high payload capacity is also developed to enable precise height(1016-2096 mm)and angle ad-justments.Additionally,this study introduces an enhanced method for data acquisition from multiple imaging sensors through registration and fusion using Zhang's calibration and feature point extraction algorithm,calcu-lating a homography matrix for high-throughput data collection at fixed positions and heights.The experimental validation results demonstrate that the RMSE of the registration algorithm does not exceed 3 pixels.The gimbal data strongly correlated with that of a handheld instrument data(r^(2)>0.90).The robot is practical,reliable,and fully functional,offering a solid theoretical foundation and equipment support for high-throughput phenotyping.
