Computational Identification and Systematic Classification of Novel Cytochrome P450 Genes in Salvia miltiorrhiza.

ABSTRACT: Salvia miltiorrhiza is one of the most economically important medicinal plants. Cytochrome P450 (CYP450) genes have been implicated in the biosynthesis of its active components. However, only a dozen full-length CYP450 genes have been described, and there is no systematic classification of CYP450 genes in S. miltiorrhiza. We obtained 77,549 unigenes from three tissue types of S. miltiorrhiza using RNA-Seq technology. Combining our data with previously identified CYP450 sequences and scanning with the CYP450 model from Pfam resulted in the identification of 116 full-length and 135 partial-length CYP450 genes. The 116 genes were classified into 9 clans and 38 families using standard criteria. The RNA-Seq results showed that 35 CYP450 genes were co-expressed with CYP76AH1, a marker gene for t
