我们通过 dCAPS 标记对来自欧亚大陆各地和其他地区的 588 个谷子材料进行了基因分型。其中，我们前期研究对480份材料的核糖体DNA（rDNA）、多酚氧化酶（PPO）基因和标题日期1（HD1）基因进行了基因分型，本研究新使用了108份来自印度的材料，除了SiDREB2基因外，还对这些基因进行了基因分型。我们将 SiDREB2 基因型的地理分布与这三个基因的地理分布进行了比较。来自包括印度和斯里兰卡在内的南亚国家的材料在SiDREB2基因中变化最大，其次是韩国材料和日本材料，这表明印度材料和东亚材料可用作耐脱水胁迫的遗传资源。这项研究还表明，尽管印度种质在 rDNA 和先前研究的转座子展示标记方面并不那么多样化，但它们在适应性基因（如 SiDREB2、PPO 和 HD1 基因）方面具有多样性。
We genotypedSetaria italica Dehydration-responsive element-binding 2(SiDREB2)gene, which had been reported to be associated with dehydration stress tolerance, in 588 accessions of foxtail millet from various parts of Eurasia and other regions by a dCAPS marker. Of these, 480 accessions were genotyped in ribosomal DNA (rDNA),polyphenol oxidase(PPO)gene andHeading date 1(HD1) gene in our previous studies, and 108 accessions from India were newly used in this study and genotyped in these genes in addition to theSiDREB2gene. We compared the geographical distribution of theSiDREB2genotypes with that of these three genes. Accessions from countries in South Asia including India and Sri Lanka were the most variable in theSiDREB2gene followed by Korean accessions and Japanese accessions, suggesting that Indian accessions and East Asian accessions are useful as genetic resources for dehydration stress tolerance. This study also showed that although Indian accessions are not so diverse in rDNA and in transposon display markers previously studied, they are diverse in adaptive genes such asSiDREB2,PPOandHD1genes.
