Transcriptome analyses reveal the expression profile of genes related to lignan biosynthesis in Anthriscus sylvestris L. Hoffm. Gen.

Anthriscus sylvestris L. Hoffm. Gen (A. sylvestris) is a perennial herb widely used for antitussive and diuretic purposes in traditional Korean and Chinese medicine. Lignans are critical secondary metabolites with widely pharmacological activities in A. sylvestris. Using transcriptome data of A. sylvestris, we identified genes related to lignan biosynthesis. In all, 123,852 unigenes were obtained from the flowers, leaves, roots, and stems of A. sylvestris with the Illumina HiSeq 4000 platform. The average length of unigenes was 1,123 bp and 91,217 (73.65%) of them were annotated in public databases. Differentially expressed genes and root-specific genes were analyzed between roots and the other three tissue types by comparing gene expression profiles. Specifically, the key enzyme genes involved in lignan biosynthesis were identified and analyzed. The expression levels of some of these genes were highest in the roots, consistent with the accumulation of deoxypodophyllotoxin. These expression levels were experimentally verified via quantitative real-time polymerase chain reaction (qRT-PCR). This research provides valuable information on the transcriptome data of A. sylvestris and the identification of candidate genes associated with the biosynthesis of lignans, laying the foundation for further research on genomics in A. sylvestris and related species.
