What is Transcriptome analysis reveals differentially expressed genes involved in somatic embryogenesis and podophyllotoxin biosynthesis of Sinopodophyllum hexandrum (Royle) T. S. Ying about?
Sinopodophyllum hexandrum (Royle) T. S. Ying, an important source of podophyllotoxin (PTOX), has become a rare and endangered plant because of over-harvesting. Somatic embryogenesis (SE) is the main way of seedling rapid propagation and germplasm enhancement, but the regeneration of S. hexandrum has not been well established, and the PTOX biosynthesis abilities at different SE stages remain unclear. Therefore, it is extremely important to elucidate the SE mechanism of S. hexandrum and clarify the biosynthesis variation of PTOX. In this study, the transcriptomes of S. hexandrum at different SE stages were sequenced, the contents of PTOX and 4'-demethylepipodophyllotoxin were assayed, and the transcript expression patterns were validated by qRT-PCR. The results revealed that plant hormone (such as auxins, abscisic acid, zeatin, and gibberellins) related pathways were significantly enriched among different SE stages, indicating these plant hormones play important roles in SE of S. hexandrum; the expression levels of a series of PTOX biosynthesis related genes as well as PTOX and 4'-demethylepipodophyllotoxin contents were much higher in embryogenic callus stage than in the other stage
