Mining of SSR markers from Expressed Sequence Tags of bamboo species.

ABSTRACT: With the ever increasing number of Expressed Sequence Tags (ESTs) from various sequencing projects, ESTs have become valuable and first-hand source of in-silico mining of simple sequence repeats (SSR) markers. We examined a total of 3419 EST sequences from three bamboo species, namely, Phyllostachys edulis, Bambusa oldhamii and Dendrocalamus sinicus for the presence of di- to hexa- microsatellites. The frequency of SSR containing ESTs varied from 5.36% in B. oldhamii to 13.05% in P. edulis. No SSRs were found in D. sinicus. Tri-nucleotide repeats (49.34%) were most frequent in P. edulis, while not much comparable difference in repeats was found in B. oldhamii. Flanking primer pairs were also designed in-silico for the sequences containing SSRs and their position on the genome hypothesized
