Analysis of transicriptomes and exploring flavonoid biosynthetic pathway genes in Lithocarpus polystachyus / 中国中药杂志

ABSTRACT

The sweet taste and health effect of Lithocarpus polystachyus are mainly related flavonoid. To obtain Lithocarpus transcriptome database and flavonoid biosynthesis-related genes, the RNA-Seq techology (Illumina HiSeq 4000) was used to sequence its transcriptome. Six Gb database was assembled after assembly steps, and 41 043 of L. polystachyus unigenes were obtained. With blasting them with 7 data banks, all unigenes were involved in 51 GO-terms and 237 metabolic pathways. And furthermore 28 genes of the flavonoid biosynthesis-related were found. After using the MicroSatallite, 18 161 SSR were obtained, the single-nucleotide-repeated was the richest at 7 346. These data represent abundant messages about transcripts and provide valuable genome data sources in molecular biology of L. polystachyus.
