Results: A total of 53, 70 and 68 significant SNPLDB loci associated with boll number (BN), boll weight (BW) and lint percentage (LP), were respectively detected through a restricted two-stage multi-locus multi-allele genome-wide association study (RTM-GWAS) procedure in multiple environments...
Two genomic regions associated with FFBN and HFFBN and a potential regulatory gene ( GhE6 ) of HFFBN were identified through the integration of RTM-GWAS and metaQTL analyses.Abstract The first fruit branch node (FFBN) and the height of the first fruit branch node (HFFBN) are two ...
Two models for genome-wide association studies (GWAS), namely restricted two-stage multi-locus multi-allele (RTM)-GWAS and mixed linear model (MLM)-GWAS, were used to dissect the genetic architecture of the agronomic traits based on 13,723 SNPs. Eleven quantitative trait loci (QTLs) for ...
Key message: Eleven QTLs for agronomic traits were identified by RTM- and MLM-GWAS, putative candidate genes were predicted and two markers for grain weight were developed and validated. Foxtail millet (Setaria italica), the second most cultivated millet crop after pearl millet, is an important ...
QTL-allele matrix detected from RTM-GWAS is a powerful tool for studies in genetics, evolution, and breeding by design of cropsThe plant germplasm resources harboring abundant genetic variations are necessary wealth in developing new cultivars adapted to various geographic and seasonal conditions. ...
Salt stressRice (Oryza sativa L.)Linkage mappingRTM-GWASRNA-seqSalinity is a major abiotic stress that limits plant growth and crop productivity. Indica rice and japonica rice show significant differences in tolerance to abiotic stress, and it is considered a feasible method to breed progeny with...
