采用InDel和SSR标记分析番茄品种基因组DNA多态性
Genomic DNA polymorphisms in tomato varieties revealed by InDel and SSR markers
摘要
Abstract
The emergency of genomic sequences in tomato (Solanum lycopersicurn L. ) provides a base for developing InDel markers. In this study, 18 InDel and 22 SSR markers were used to analyze genomic DNA diversity in 59 Chinese and 23 US fresh-market tomato varieties to investigate the potential use of InDel markers in tomato molecular breeding.Comparison between 59 Chinese and 23 US varieties were also conducted at marker level. The results indicated that InDel marker showed lower polymorphisms than SSR markers in 82 varieties. The number of alleles amplified by InDel primers was significantly lower than that amplified by SSR markers in Chinese varieties. But no obvious difference was observed in US varieties. The number of alleles amplified by InDel primers was significantly lower in Chinese varieties than in US varieties. Cluster analysis indicated that genetic difference was very low among varieties developed by Chinese breeding programs but relatively high between Chinese and foreign varieties.关键词
