摘要

本研究检测了244个玉米近交系中4种类胡萝卜素的含量，并对约300万个单核苷酸多态性（SNPs）进行了全基因组关联研究，初步分析了玉米籽粒类胡萝卜素的遗传机制。我们发现了826个与类胡萝卜素含量显著相关的数量性状位点（QTLs），并得到了两个关键候选基因Zm00001d029526（CYP18）和Zm00001d023336（wrky91）。此外，我们还发现了一个类胡萝卜素含量较高的种质 IL78。本研究的结果可为筛选基因提供理论依据，从而指导核仁类胡萝卜素的选育。

Genome-wide association study of carotenoids in maize kernel.

In this study, the contents of four carotenoids in 244 maize inbred lines were detected and about three million single nucleotide polymorphisms (SNPs) for genome-wide association study to preliminarily analyze the genetic mechanism of maize kernel carotenoids. We identified 826 quantitative trait loci (QTLs) were significantly associated with carotenoids contents, and two key candidate genes Zm00001d029526 (CYP18) and Zm00001d023336 (wrky91) were obtained. In addition, we found a germplasm IL78 with higher carotenoids. The results of this study can provide a theoretical basis for screening genes that guide kernel carotenoids selection breeding.
