摘要：High-throughput sequencing of the Phoebe bournei transcriptome was performed, and novel SSR markers were identified. A total of 73,518 nonredundant unigenes were assembled and annotated by sequence similarity searching in diverse public databases. A total of 40,853 SSRs were identified from 73,518 unigenes. Twenty-three pairs of polymorphic EST-SSR markers were selected from 98 markers and used for genetic analyses in 75 individuals from three P. bournei populations. The 23 pairs of markers could detect abundant genetic information from the samples (PIC = 0.769), and cross-species amplification was successfully performed in other related species. Three populations had high level of genetic diversity (He = 0.658 in average), of which the population YS from Jiangxi province had the most abundant genetic diversity (He = 0.722). The results of genetic structure analyses showed that the population YS from Jiangxi province had obvious genetic differences from the other two populations, and the genetic information of the population SX from Fujian province was related to that of the population LC from Guangdong province and the population YS. The transcriptomic resources and EST-SSR markers are valuable tools not only for the ecological conservation of P. bournei but also for phylogenetic studies.
