multi trait gwas

The interaction model identifies SNPs that act differentially for the two traits or locations. Phenotypic diversity for seed mineral concentration in North American dry bean germplasm of MA ancestry. In this way, we can pool the Z data across locations or stresses to discover common factors affecting the trait. Given proper flowering conditions, this trait can be an indicator of yield potential. It can also be used as a tool to meta-analyze GWAS results. Major consumers of common bean in these countries often live on less than two U.S. dollars per day, where beans are grown primarily by smallholder farmers on less than two hectares (McClean and Raatz 2017). 2014). Neurobiol Stress. We tested that premise on two data sets. A mixed-model approach for genome-wide association studies of correlated traits in structured populations. Whereas the BASE_120 and BASE_Meso consist primarily of cultivars and advanced breeding lines, the BASE-Andean contains a large portion of landraces from East Africa. The GWA analyses can be done on individual level data or on single-trait GWA summary statistics only. http://biorxiv.org/content/early/2017/03/11/115915.abstract, G1001799/MRC_/Medical Research Council/United Kingdom, P01 HD031921/HD/NICHD NIH HHS/United States, MR/N01104X/2/MRC_/Medical Research Council/United Kingdom, R01 HD060726/HD/NICHD NIH HHS/United States, MC_QA137853/MRC_/Medical Research Council/United Kingdom, R01 HD073342/HD/NICHD NIH HHS/United States, R01 MH107649/MH/NIMH NIH HHS/United States, U01 MH109539/MH/NIMH NIH HHS/United States, 647648/ERC_/European Research Council/International, P30 AG034532/AG/NIA NIH HHS/United States, R01 MH101244/MH/NIMH NIH HHS/United States, P01 AG005842/AG/NIA NIH HHS/United States, P30 AG012810/AG/NIA NIH HHS/United States, R01 AG042568/AG/NIA NIH HHS/United States, T32 AG000186/AG/NIA NIH HHS/United States, eScholarship, California Digital Library, University of California, Galesloot TE, Van Steen K, Kiemeney LALM, Janss LL, Vermeulen SH. MTAG accounts for both sources of overlap. The predicted functional effect of each SNP was obtained from a SNPeff database developed for all SNPs using snpEFF.jar with “build-gff3” (Cingolani et al.2012). Recently, an increasing number of GWAS summary statistics have been made available to the research community, providing extensive repositories for studies of human complex diseases. The shared SNP data set from the phylogenetic analysis of all genotypes was used for a Bayesian population structure analysis with the program STRUCTURE 2.3 (Pritchard et al. 2017), and domestication traits such as increased leaf and seed size (Schmutz et al. Supplemental material available at Figshare: https://doi.org/10.25387/g3.7965305. Our members work to advance knowledge in the basic mechanisms of inheritance, from the molecular to the population level.

This tree was developed with the 5,637 SNPs shared between the MA and Andean SNP data sets. 1993, 1996) while being monomorphic in the other pool regardless of whether the genotype is resistant or susceptible. 2016). Each gene pool has specific agronomic, morphological, physiological and molecular characteristics, and allele frequencies differ between the two gene pools for genetic factors controlling a trait (Singh et al. Recently, multi-trait mixed models (MTMM) statistical methods have been developed to uncover common genetic effects that act in a pleiotropic manner on two correlated traits (Korte et al. 2016). Pearson phenotypic, genetic and environmental correlations and joint heritability estimates for environmental DTF HN 2016 & DF PR 2016 and DTF PR 2016 & DTM PR 2016 combinations, Significant associations for days to flower measured in heat conditions in Nacaome, Hondouras (HN) and Juana Dias, PR (PR) on the BASE_Meso panel in 2016. Regression-based test of replicability of MTAG-identified loci, Fig. The authors would also like to thank Rian Lee (North Dakota State University) and Sujan Mamidi (Hudson Alpha Institute of Biotechnology) for their lab support and professional guidance. Func. There are now ∼260k SNPs available for a large collection of Andean genotypes. In this context, a multi-trait GWAS might help to explain these correlations. A genetic discovery population carefully designed to include variation for response to heat and/or drought stress is important for discovering critical genetic factors associated with the abiotic stress response. This peak QTL region is located in a cluster of chitinase genes. Final subpopulation graphics were produced by the Distruct 1.1 program. This result suggests that genetic factors that are common or show an interaction effect of significance between the two heat stress environments may be discovered. Quantitative trait loci associated with drought tolerance in common bean. The phenotypic and genotypic data were then analyzed using single trait mixed linear model (MLM; Yu et al. Performing multivariate genome-wide association (MVGWA) analyses.

We demonstrate that the multi-trait method can be used to increase the power (numbers of SNPs validated in an independent population) of GWAS in a beef cattle data set including 10,191 animals genotyped for 729,068 SNPs with 32 traits recorded, including growth and reproduction traits. The peak SNP in each analysis was located at Pv04:4,665,828 bp and accounted for 8.9 and 7.8% of the variation, respectively, for the heat and drought trials. The peak common effect for DTF in the MTMM analysis of flowering under heat stress in HN and PR was also on Pv03 and mapped 40kb (and one gene away) from Phvul.003G239000 at Pv03:47.36 Mb. GCTA currently supports the following analyses. Social Science Genetic Association Consortium. The primary role of HOS15 is the regulation of flowering under cold stress. At the proximal end of this interval, gene model Phvul.003G181900 is located. Multivariate simulation framework reveals performance of multi-trait GWAS methods. 5. The MTMM statistical method and scripts (, Centro Internacional de Agricultura Tropical. In the latter case, this interaction reflects the genotype x environment interaction effect that is important in the context of breeding for multiple environments. Effects of high‐temperature stress on microsporogenesis in heat‐sensitive and heat‐tolerant genotypes of. Detecting the number of clusters of individuals using the software STRUCTURE: a simulation study. 2018). Theory suggests that larger population sizes can uncover either large or small effect size genetic factors while smaller size populations tend to discover only effects of larger size (Korte and Farlow 2013). 5. Therefore, there is a real need to improve common bean productivity in these regions for fast growing populations that will be affected by anticipating future conditions brought on by climate change (Beebe et al. Collectively, these three SNPs accounted for 17.6% of the observed variation. Green are the BASE_Meso genotypes and purple and the BASE_Anjdean genotypes. 2014; Brisco et al. 7. Sl-IAA27 gene expression is induced during arbuscular mycorrhizal symbiosis in tomato and in Medicago truncatula. -, Hu Y, et al. k = 2, was optimum number of subpopulations for the BASE populations. 2017, 2018). We apply MTAG to summary statistics for depressive symptoms (N eff = 354,862), neuroticism (N = 168,105), and subjective well-being (N = 388,538). 2020 Oct 19;16(10):e1009089. In contrast, here the BASE_120 and the BASE_Meso panels were developed for the purposes of mapping genetic factors in germplasm important for Central America and Caribbean production regions. (C) Joint 2014 and 2015 Macrophomina infection rating GWAS analysis for BASE_120 grown under in Puerto Rico. 2018). 2011a; Schmutz et al. 2000). The first GWAS panels developed for common bean, the MA (Mafi Moghaddam et al. The full model also out-performed the individual marginal analyses when DTF and DTM data were considered jointly. For Juana Diaz, the panels were grown in separate drought and heat experiments, using a lattice design with three replications in 2014, an RCBD design with three replications in 2015, and an RCBD design with six replications under drought and four replications under heat in 2016. A Phaseolus vulgaris diversity panel for Andean bean improvement. 2015a), flooding tolerance (Soltani et al., 2018), and agronomic traits such as phenology, aboveground biomass, and seed yield (Kamfwa et al. We introduce Multi-Trait Analysis of GWAS (MTAG), a method for joint analysis of summary statistics from GWASs of different traits, possibly from overlapping samples. Candidate genes were selected from an interval that ranged from 50kb upstream to 50kb downstream of the peak SNP using the common bean v2.1 gene models (https://phytozome.jgi.doe.gov/). 1. Here we report on the development of these moderate-sized panels and the results obtained by combining SNP genotyping data of these panels with those of the MDP and ADP to generate large SNP marker collections for each gene pool. (F Joint heat and drought SPAD reading GWAS analysis. These HapMaps were based on 381,092,199 GBS reads across 469 MA genotypes and 280,085,901 GBS reads across 325 Andean genotypes. -, Maier R, et al. This is encouraging for marker assisted breeding because only a single or a few markers may be needed for selection for days to flower in these two heat stress environments.

Kiel C, Strunz T, International Amd Genomics Consortium Project Manager Susan Blanton Iamdgc, Grassmann F, Weber BHF. 2012; Mukeshimana et al. GCTA (Genome-wide Complex Trait Analysis) was initially designed to estimate the proportion of phenotypic variance explained by all genome-wide SNPs for complex traits (i.e., the GREML method). Multi-trait GWAS We used the following MTM-GWAS that does not account for the inferred network structure by extending the single-trait GWAS counterpart of Kennedy et al. The critical step is placing the phenotypic data on a standard scale. Row length was 2.5 m. Phenotypic data collected included seed yield (kg ha-1), days to flowering (DTF) recorded when 50% of the plants had at least one open blossom, Macrophomina phaseolina disease severity scored from 1 to 9 (Abawi et al. We introduce multi-trait analysis of GWAS (MTAG), a method for joint analysis of summary statistics from genome-wide association studies (GWAS) of different traits, possibly from overlapping samples. Receptor protein kinase genes are one component of the plant immune signaling system (Tena et al. This interval was also detected in the combined analysis (Figure 4F). 2019 Aug;51(8):1295. doi: 10.1038/s41588-019-0469-9. The highest level of expression for this gene was noted in flower buds relative to other developmental and anatomical tissues (https://phytozome.jgi.doe.gov/pz/portal.html#!info?alias=Org_Pvulgaris).

Long-term effects of stress early in life on microRNA-30a and its network: Preventive effects of lurasidone and potential implications for depression vulnerability. SNPs with <50% missing data were imputed using fastPHASE (Scheet and Stephens 2006). The significance level was calculated using a Bonferonni test based on the effective number of markers (n = 463) as determine by the simpleM algorithm (Gao et al. A cell-free method for expressing and reconstituting membrane proteins enables functional characterization of the plant receptor-like protein kinase FERONIA. 2014;9:e95923. Repeated studies have shown genetic diversity is greater among domesticated MA beans than domesticated Andean beans (Velasquez and Gepts 1994; Mamidi et al. The BASE_Andean panel contained 124 genotypes. 2014; Bello et al. 2009) were used to align the data against reference genome Phaseolus vulgaris v2.1, and to index, and sort the aligned reads (https://phytozome.jgi.doe.gov/pz/portal.html#!info?alias=Org_Pvulgaris).

Automated feature extraction from population wearable device data identified novel loci associated with sleep and circadian rhythms. The density of SNPs is essentially equal across the full genome of the two gene pools with an enrichment of SNPs in the heterochromatic regions. We do not retain these email addresses. Inference of population structure using multilocus genotype data. We apply MTAG to summary statistics for depressive symptoms (N The major SNP peak under heat (Figure 4D) was located at Pv09:17,981,113 (P = 1.08E-6) and accounted for 12.7% of the phenotypic variation (Table S2). Pooling data across different experiments to extract factors that affect a phenotype across those experiments normally assumes the population parameters across the two experiments are equal. Large scale SNP data sets for the two major gene pools of bean, Andean and Middle American, were developed by mapping multiple pools of genotype-by-sequencing reads and identifying over 200k SNPs for each gene pool against the most recent assembly of the P. vulgaris genome sequence. Two distinct clades were observed that separated the MA and Andean genotypes. 2015 Nov;47(11):1236-41. doi: 10.1038/ng.3406. Methods for meta-analysis of multiple traits using GWAS summary statistics. GWAS were performed for each trait in each location under different stress conditions using untransformed data. 2014) in distinct locations to form two distinct domesticated clades. Across the multi-trait methods, mvGWAS had a slightly higher true-positive detection rate than the PC1 GWAS when all of the simulated trait heritabilities were either 0.9 or 0.5.

This research was supported by USAID Feed the Future Innovation Laboratory for Climate-Resilient Beans through grant USAID OAA-A-13-00077. The genotypes used to develop the HapMaps represent many of genotypes used for production purposes over the last 50 years in the USA and elsewhere. The association between each quantitative trait and the genome-wide SNPs was analyzed with the GAPIT R package (Lipka et al. Demographic factors shaped diversity in the two gene pools of wild common bean. This was expected because beans grown in the target Central American region are almost exclusively from race Mesoamerica of the MA gene pool. 3. 2020 Nov 19;8(1):196. doi: 10.1186/s40478-020-01072-8.

Investigation of multi-trait associations using pathway-based analysis of GWAS summary statistics. The discovery that a common bean malectin/receptor-like protein kinase homolog can act as a disease resistance gene supports the hypothesis that a member of the Pv04 cluster can be a strong candidate to provide M. phaseolina resistance. Joint modeling of genetically correlated diseases and functional annotations increases accuracy of polygenic risk prediction. The objective of the second MTMM analysis was to discover genetic factors with pleiotropic effects for both DTF and DTM under heat stress (Figure 5B). Many genetic variants identified in genome-wide association studies (GWAS) are associated with multiple, sometimes seemingly unrelated, traits. By contrast, association panels can sample variation across a larger number of genotypes and be used to discover both large or small effect genetic factors that are associated with the plant’s response to abiotic stress conditions (Risch 2000; Mamidi et al. The A allele at the peak SNP was associated with lower disease incidence in the two trials. 2015 and Li et al. 2010). For the MA SNP collection, there are 1.79x SNPs in the heterochromatic region compare to the euchromatic region, while that ratio for the Andean SNP collection is 1.51x. An admixture model of independent allele frequencies with 20,000 burn-ins and 10,000 MCMC replication for subpopulation sizes of K = 1 to 10 was implemented (McClean et al. The major genetic association of HOS15 with flowering under heat stress might suggest the gene may act as control factor under multiple temperature stresses. BASEMeso = green; BASEAndean = blue. 2011). Three other SNPs (Pv08:9,135,122 bp, Pv11: 41,873,950 bp; Pv11: 47,305,350 bp) defined other individual loci, and each accounted for more than 7% of the variation, and along with the peak SNP, these four SNPs collectively accounted for 20.2% of the variation in yield under heat stress (Table S2). DUF538 proteins are putative chlorophyll hydrolyzing enzymes that function in the ROS detoxification system when the plant is exposed to heat and drought stress (Gholizadeh et al. 2. The common model identifies SNPs that act in the same direction for the two traits or locations. Turley P, Walters RK, Maghzian O, Okbay A, Lee JJ, Fontana MA, Nguyen-Viet TA, Wedow R, Zacher M, Furlotte NA; 23andMe Research Team; Social Science Genetic Association Consortium, Magnusson P, Oskarsson S, Johannesson M, Visscher PM, Laibson D, Cesarini D, Neale BM, Benjamin DJ. 2005), which calculates the total change in log probability of data between consecutive k values, was used to determine the number of clusters. Eight Andean genotypes (green in Figure 2B), including G13654, G2377, G23829, SAB_6292, SEQ_11, 754_3 and 379_PI_203934, were grouped with BASE_Meso genotypes despite being selected as members of the BASE_Andean panel. Multi-trait GWAS Simulator User Manual Heather F. Porter & Paul F. OâReilly multitraitgwas@gmail.com MRC Social, Genetic and Developmental Psychiatry Centre, Contents 1 Background 3 2 Software program 4 3 R packages 4 4 MA and Andean SNPs were derived from 482 and 325 genotypes, respectively. Moreover, association statistics from MTAG yield more informative bioinformatics analyses and increase the variance explained by polygenic scores by approximately 25%, matching theoretical expectations. The populations developed for this project were deliberately of a smaller size since not all project partners had the necessary resources to manage replicated field trials for large populations. The range of SNPs per Mb is consistent across both and heterochromatic of the and Andean SNP data sets (Table S3). SNPs within or near candidate genes associated with hormone signaling, epigenetic regulation, and ROS detoxification under stress conditions were identified and can be used as genetic markers in dry bean breeding programs. 2016 and Kessler et al. Fig. Compare GWAS locus for multiple traits within given region. Pearson phenotypic, genetic, and environmental correlations and heritabilities were estimated using the MTMM software (Korte et al. 2016). The critical P -value for significant QTNs in the GEMMA and EMMAX methods was determined by Bonferroni correction: Î± =1/54 294 = 1.84×10 â5 ( Xu et al ., 2018 b ; Zhang et al ., 2019 b ). The malectin/receptor kinase/RALF complex has a negative effect on the plant immune system by preventing the modulation of FLS2-BAK1 (FLAGELLIN-SENSING2/ BRASSINOSTEROID INSENSITIVE 1–associated kinase) complex mediated by FER.

Figure 3C shows that selection for the early DTF allele will have a positive effect on yield performance under high heat conditions. Yield GWAS results for the panel grown under heat in Honduras and Puerto Rico in 2016. The MTMM analysis of DTF data from the BASE_Meso population grown in HN and PR under heat in 2016 showed the full joint analysis out-performed individual marginal analyses (Figure S2). Importantly for small population sizes, the power of the MTMM approach is greater than the marginal GWAS tests typical of mixed model statistical methods because of the additional power obtained when data for the two traits (or environments) are considered jointly (Korte et al. 2015). | MLM GWAS analysis for BASE panels. The peak QTL region for DTF in the joint MLM analysis under heat stress in HN and PR is located on Pv03 at 40.48-40.50 Mb. The SPAD rating under heat stress is one indicator of variation in the response to heat stress. Because the BASE_Andean panel was developed for research in African countries, a subset from the Andean Diversity Panel was chosen. Population structure and genetic differentiation among the USDA common bean (Phaseolus vulgaris L.) core collection. Previously, the ADP had only been genotyped with the ∼6k SNPs from the BARCBean 6K_3 BeadChip (Song et al. Multivariate genome-wide analysis of education, socioeconomic status and brain phenome. Pei G, Sun H, Dai Y, Liu X, Zhao Z, Jia P. BMC Genomics. In the settings where the heritabilities simulated This phenotype data were then coupled with a robust SNP data set built with reads from a much larger set of individuals from a diverse pool of genotypes that represented the genetic diversity of the two bean gene pools. Phylogenetic analyses demonstrated the BASE populations represented broad genetic diversity for the appropriate races within the two gene pools. There were no significant loci for single-trait BH6 (sin-gle-trait GWAS for BH at 6months after birth, and so forth), single-trait AS6, single-trait CS6, and LONG-AS.
