Genetic Relationship of Physalis Plants Revealed by Simple Sequence Repeat Markers
摘要
Abstract
In recent years, Physalis plants have attracted increasing attention worldwide due to their high nutritional value, edible fruit, and potential medicinal value. In this study, simple sequence repeat (SSR) markers were used to assess genetic relationships with 22 samples of four Physalis species mainly distributed in China. Twenty SSR primer pairs produced 118 loci, 90.7％ (107) of which showed polymorphism. The average interspecies similarity coefficient was 0.501, which indicates a degree of genetic relationship among Physalis species. The results of UPGMA dendrography and PCoA plotting were similar, and all Physalis samples were grouped into two clusters. All P. alkekengi var. francheti samples, distant from any other Physalis species, constituted a separate cluster, which confirmed findings of previous studies. This study also indicated that SSR markers are rich in genetic information and could be used to assess the genetic diversity of Physalis species which provides rich useful information for protecting the Physalis germplasm resource and an important foundation for molecular assisted-breeding programs with Physalis.关键词
