Molecular identification and expression of sesquiterpene pathway genes responsible for patchoulol biosynthesis and regulation in Pogostemon cablin.

ABSTRACT:

Background

Many commercially important drug and flavor compounds are secondary metabolites of terpenoid origin. Pogostemon cablin, a commercially important industrial and medicinal crop, accumulates abundant patchouli oil comprised of more than 24 unique sesquiterpene compounds, with the most abundant being patchouli alcohol.

Results

In this study, we analyzed the P. cablin transcriptome library, obtaining 74 terpenoid biosynthesis-related genes, and identified their expression patterns in leaves, stems, and flowers. These genes are members of 15 different families, and we detected all the enzymes involved in the sesquiterpenes pathway that are responsible for patchoulol biosynthesis. Sequence structure, homology, conserved domain properties, and phylogeny of certain identif
