桃（Prunus persica L.）是一种非常有价值的作物物种，被分子研究人员认为是蔷薇科的模式水果。利用来自129份桃种质的全基因组测序数据，我们对12个关键农艺性状进行了全面的全基因组关联研究。我们发现，在调查的10个质量性状中，有9个表现出一致的和更精确的关联信号比以前确定的连锁分析。对于两个定性性状，我们描述了候选基因，一个可能参与细胞死亡，另一个预测编码的生长素外排载体，这是高度相关的果形和非酸性，分别。此外，我们发现，几个基因组区域窝藏关联信号的果实重量和可溶性固形物含量重叠预测的选择性扫描，发生在桃驯化和改进。我们的研究结果有助于桃农艺性状控制基因的大规模表征。 桃是重要的经济作物，也是蔷薇科果实发育研究的模式植物。在这里，作者在桃中进行了全基因组关联分析，并找到了与农艺学上重要的果实表型变异相关的候选基因。
Peach (Prunus persica L.) is a highly valuable crop species and is recognized by molecular researchers as a model fruit for the Rosaceae family. Using whole-genome sequencing data generated from 129 peach accessions, here we perform a comprehensive genome-wide association study for 12 key agronomic traits. We show that among the 10 qualitative traits investigated, nine exhibit consistent and more precise association signals than previously identified by linkage analysis. For two of the qualitative traits, we describe candidate genes, one potentially involved in cell death and another predicted to encode an auxin-efflux carrier, that are highly associated with fruit shape and non-acidity, respectively. Furthermore, we find that several genomic regions harbouring association signals for fruit weight and soluble solid content overlapped with predicted selective sweeps that occurred during peach domestication and improvement. Our findings contribute to the large-scale characterization of genes controlling agronomic traits in peach. Peach is both an economically important crop species and a model for Rosaceae fruit development research. Here, the authors perform genome-wide association analysis in peach and find candidate genes associated with variation in agronomically important fruit phenotypes.
