利用SSR分析华中、华东五大湖区野生菰的遗传结构与多样性
Genetic Diversity and Genetic Structure of Zizania latifolia Griseb (Turcz) From Middle-East China Based on SSR Analysis
摘要
Abstract
In order to further understand the survival condition and evolution of Z.latifolia in China,seven SSR markers were used for genetic diversity and genetic structure analysis of 26 wild populations from the Middle-East China.The results of POPGENE analysis showed that there was rich genetic diversity among the wild species (PPB =92.19％,Ao =1.922,Ae =1.454,He =0.274,I =0.422,Gst =0.673) and the genetic similarity coefficient and genetic distance were between 0.5569 ～0.9981 and 0.0019 ～0.5854,respectively.With the genetic structure analysis,26 populations were divided into three groups and there was no significant association between the phylogenetic relationship and the geographic locations in the Z.latifolia populations.The evolution analysis showed that 26 populations were separated from the same ancestor into two branches.This study deepens our understanding about the genetic evolution of Z.latifolia in the Middle-East China and provides certain theoretical basis for protection of the wild rice germplasm resource.关键词
