Transcriptome Sequencing and Analysis of SSR Characteristics of Camellia oleifera

With the sequencing data of Camellia oleifera as the research base, the SSR was searched through MISA software, and the SSR characteristics were analyzed and evaluated. The results showed that a total of 104 515 SSR were found and distributed in 80 724 Unigenes. The distribution density and the average frequency of occurrence were 1/1.48 kb and 33.58%, respectively. MNRs and DNRs were the major nucleic acid repeat types. A/T and AG/CT were the dominant repetitive bases. The proportion of the 10 repeats was the highest. The motifs′ length was concentrated at 12-20 bp, which was accounted for 51.71%. The SSR in the transcriptome of C.oleifera have significant quantitative advantages, rich types and good polymorphism potential.
