摘要： In this study, we analyze the genetic diversity and phylogeny of photoperiod related genes Hd1 and Ehd1 in Oryza rufipogon populations from Hainan Island and Guangdong province separated by the Qiongzhou Strait. The levels of variations in Hd1 and Ehd1 of O. rufipogon from Hainan Island were higher than those from Guangdong province, although their polymorphism distribution trends were similar. The haplotype phylogenetic analysis showed that the genetic diversity of O. rufipogon from Hainan Island was richer than that from Guangdong province. The phylogenic networks of individuals based on either Hd1 or Ehd1 or the combination of these genes indicated that the differentiation of O. rufipogon did not occur due to geographic isolation. Our findings suggest that different ecological niches seem to have significant impacts on the genetic differentiation of O. rufipogon populations.
