Development and characterization of 1,827 expressed sequence tag-derived simple sequence repeat markers for ramie (Boehmeria nivea L. Gaud).

ABSTRACT: Ramie (Boehmeria nivea L. Gaud) is one of the most important natural fiber crops, and improvement of fiber yield and quality is the main goal in efforts to breed superior cultivars. However, efforts aimed at enhancing the understanding of ramie genetics and developing more effective breeding strategies have been hampered by the shortage of simple sequence repeat (SSR) markers. In our previous study, we had assembled de novo 43,990 expressed sequence tags (ESTs). In the present study, we searched these previously assembled ESTs for SSRs and identified 1,685 ESTs (3.83%) containing 1,878 SSRs. Next, we designed 1,827 primer pairs complementary to regions flanking these SSRs, and these regions were designated as SSR markers. Among these markers, dinucleotide and trinucleotide repeat motifs we
