De Novo characterization of a Cephalotaxus hainanensis transcriptome and genes related to paclitaxel biosynthesis.

ABSTRACT: Cephalotaxus hainanensis, an endangered plant, is known to contain several metabolites with anti-cancer activity. Despite its clinical impact, the alkaloid metabolism of this species has remained largely uncharacterized. The potential of Cephalotaxus for metabolic engineering of medically interesting compounds has, so far, not been exploited, due to the almost complete lack of molecular information. We have therefore performed a high throughput RNA-seq analysis and assembled the transcriptome de novo. Raw reads comprising 4.3 Gbp were assembled de novo into 39,416 unique sequences (unigenes) with a mean length of 1,089.8 bp and a total assembly size of 45.8 Mbp, which equals to more than 50 times the number of Cephalotaxaceae sequences currently deposited in the GenBank (as of August 2013)
