The dirigent multigene family in Isatis indigotica: gene discovery and differential transcript abundance.

ABSTRACT:

Background

Isatis indigotica Fort. is one of the most commonly used traditional Chinese medicines. Its antiviral compound is a kind of lignan, which is formed with the action of dirigent proteins (DIR). DIR proteins are members of a large family of proteins which impart stereoselectivity on the phenoxy radical-coupling reaction, yielding optically active lignans from two molecules of E-coniferyl alcohol. They exist in almost every vascular plant. However, the DIR and DIR-like protein gene family in I. indigotica has not been analyzed in detail yet. This study focuses on discovery and analysis of this protein gene family in I. indigotica for the first time.

Results

Analysis of transcription profiling database from I. indigotica revealed a family of 19 full-length unique DIR a
