Abstract:
Objective: To obtain the transcriptome sequence database and differentially expressed genes of Asarum sieboldii, and to identify the genes related to the biosynthesis of methyleugenol, the main chemical compound in this species. Methods: Roots and leaves of the plants were chosen as experiment materials. The transcriptome sequence database was constructed by applying an Illumina Hiseq 4000 Sequencing Platform. Unigenes were assembled by BLAST similarity searches and annotated with GO and KEGG orthologs identifiers. Moreover, differentially expressed genes were analyzed. Results: 12.25 Gb database was obtained, among which 129 003 unigenes were annotated to be involved in 52 GO-terms and 363 metabolic pathways. After analysis, 439 differentially expressed genes were observed, the up-regulated genes account for 38.3% and the down-regulated genes account for 61.7%. In addition, 136 unigenes involved in phenylpropanoid biosynthesis in A. sieboldii, and 44 unigenes that were associated with biosynthesis of methyleugenol were identified. Conclusion: Unigenes explored in this study will significantly contribute to genome-wide research and analysis of this species.
