【摘要】In order to develop SSR markers and provide powerful tools for the molecular marker-assisted breeding of jute, the SSR loci from transcriptome
sequences
were
searched
by
MicroSAtellite
(MISA)software, and the polymorphism of some SSRs were identified. The result showed that:1)A total of 8 571 locus, which were longer than 1 kb and accounted for 62. 47%of the screened Unigenes, were identified from 13 718 Unigenes, resulting in one SSR per 3. 47 kb on average;2)Mononucleotide repeat was the most abundant repeat type, accounting for 42. 15% of the total number of SSRs. The dinucleotide and trinucleotide repeat were less abundant, which ratio was 14. 80% and16. 74%, respectively;3)A total of 880 primers related to lignin synthase gene and MYB transcription factor were designed by Primer 3. 0, among which 29 were screened and 8 pairs of primers produced polymorphic bands. The ratio of polymorphic primers was 27. 58%. In conclusion, it is feasible to develop SSR molecular markers based on transcriptome sequencing analysis of jute, which could be applied for analyzing genetic diversity, genetic linkage mapping and functional gene mining of jute.%为开发黄麻SSR引物,为黄麻分子标记辅助育种等研究
