摘要: Microsatellite sequences were determined from Musa balbisiana, a wild diploid species in China, using selectively amplified microsatellite analysis. Fourteen microsatellite loci were evaluated in a collection of 22 cultivated bananas and 11 wild species. A total of 77 alleles were detected with an average of 5.5 alleles and heterozygosity (H) = 0.355 per locus. Efficient loci transferability of M. balbisiana simple sequence repeat markers across other wild species of the genus was observed. Sequencing alleles at four loci showed that, apart from microsatellite length variation, point mutations and insertions/deletions were quite abundant, especially when comparing Musella lasiocarpa and Ensete glaucum with the other Musa species/subspecies. In the sequenced regions, some single-nucleotide polymorphisms were identified which distinguished M. lasiocarpa and E. glaucum from the other Musa species.
