摘要: Using GWAS, 13 significant SNPs distributed on six of the seven Aegilops tauschii chromosomes (all but 5D) were identified, and several candidate P-deficiency-responsive genes proposed from searches public databases. tauschii, wheat (Triticum aestivum) D-genome progenitor, possesses numerous for stress resistance, including tolerance phosphorus (P) deficiency. Investigation genetic architecture A. will help in developing P-deficiency-tolerant varieties wheat. We evaluated nine traits a population 380 specimens under conditions with without P application, we performed genome-wide association studies these using single nucleotide polymorphism (SNP) chips containing 7185 markers. general linear model, identified 119 that significantly associated all traits, mixed model revealed 18 traits. Both models detected markers 5D). Searches databases candidate/flanking related to P-deficiency tolerance. These grouped five categories by types proteins they encoded: defense response proteins, enzymes, promoters transcription factors, storage or triggered The contain essential information cloning wheat, provide foundation breeding tolerant cultivars.
