背景识别小麦产量和品质相关性状的基因座并剖析其遗传结构对于小麦育种至关重要。采用高密度90 K SNP阵列进行全基因组关联研究，分析543个面包小麦品种的产量和品质相关性状。结果21条染色体上共分布11，140个多态性SNP，其中270个显著SNP与25个产量和品质相关性状相关。此外，基于BLUP数据，在显著SNPs附近检测到638个候选基因，其中包括3个与小穗数、第一节间直径和籽粒体积相关的候选基因（TraesCS 7A 01 G482000、TraesCS 4 B 01 G343700和TraesCS 6 B 01 G295400）。使用源自RNA-seq分析的阶段特异性和组织特异性基因表达数据进一步分析三种候选基因。这些基因是很有前途的候选人，提高产量和品质相关的性状在小麦。ConclusionsThe研究结果提供了一个新的见解，了解小麦产量和品质的遗传基础。本研究所获得的标记可用于小麦育种中的标记辅助选择。
BackgroundIdentifying the loci and dissecting the genetic architecture underlying wheat yield- and quality-related traits are essential for wheat breeding. A genome-wide association study was conducted using a high-density 90 K SNP array to analyze the yield- and quality-related traits of 543 bread wheat varieties.ResultsA total of 11,140 polymorphic SNPs were distributed on 21 chromosomes, including 270 significant SNPs associated with 25 yield- and quality-related traits. Additionally, 638 putative candidate genes were detected near the significant SNPs based on BLUP data, including three (TraesCS7A01G482000,TraesCS4B01G343700, andTraesCS6B01G295400) related to spikelet number per spike, diameter of the first internode, and grain volume. The three candidate genes were further analyzed using stage- and tissue- specific gene expression data derived from an RNA-seq analysis. These genes are promising candidates for enhancing yield- and quality-related traits in wheat.ConclusionsThe results of this study provide a new insight to understand the genetic basis of wheat yield and quality. Furthermore, the markers detected in this study may be applicable for marker-assisted selection in wheat breeding programs.
