    Abstract:

    In this study, 11,150 qualified ESTs(including 10 cDNAs), about 8.1×106 bp in length, were downloaded from ESTs databases of Lentinula edodes in Fungal Genomics Project(FGP) and NCBI. By searching with SSRhunter 1.3 and handwork, 469 SSRs were identified in 316 ESTs, approximately 2.83% of total ESTs. The average distance between SSRs was about 17.3kb. Trinucleotide and hexanucleotide ESR-SSRs were found to be the two most aboundent repeats, accounting for 38.00% and 20.00% of the total ESR-SSRs respectively. The most familiar motifs are(A)n,(T)n,(GA)n,(AG)n,(TGA)n,(GAT)n and(TCTTT)n, which comprised about 35.94% of all EST-SSRs.
