Next generation sequencing and transcriptome analysis ofroot bark from Paeonia suffruticosa cv.Feng Dan
Moutan Cortex is an important traditional Chinese medicine, "Fengdan Pi" was known as Dao-di herbs from the root bark of Paeonia suffruticosa cv.Feng Dan for its extracted various active components.However, the genetic basis for their activity is virtually unknown.The transcriptome of the root bark from "Fengdan" was sequenced using the Illumina HiSeq 4000 sequencing platform.The clean reads were then de novo assembled into 72 997 unigenes.Among them, the number of unigenes which could been annotated by dataset Nr and GO was 41 139 and 34 592.The 20 016 unigenes could been annotated by KEGG dataset, which were involved in 5 major categories, 34 middle categories, and 352 metabolism pathways.The number of unigenes which were mapped to the phenylpropanoid biosynthesis pathway, terpenoid backbone biosynthesis pathway, terpenoid biosynthesis pathway, alkaloid biosynthesis pathway, and flavonoid biosynthesis pathway was 214, 104, 152, 55 and 36 respectively, suggesting that they are involves in these pathways of pharmaceutically important.Furthermore, there also showed remarkable differences in groups which enrichment ratio of the different expressed gene compared.In addition, a total of 9 939 SSRs were identified from the sequence of 72 997 unigenes.This study not only provides many valuable basal data which was important gene in the synthesis pathway of secondary metabolites with gene searching, but also has important significance to find molecular marker in germplasm for breeding and improvement.
