Cephalotaxus hainanensis leave Transcriptome with and without MeJA treatment. Cephalotaxus hainanensis

In previous work, cephalotaxine, harringtonine, homoharringtonine were shown to be accumulated differentially after various stimuli. Especially, after MeJA treatment, the concentration of 3 cephalotaxus alkaloids all showed decreasing. We speculated that the genes expressed lower after MeJA treatment might encode some enzymes responsible for the biosynthesis of cephalotaxus alkaloids. Therefore, choosing the sample treated with MeJA and the control sample for comparative transcriptome and iTRAQ analysis will greatly facilitate dissection of the genes involved in the biosynthesis of cephalotaxus alkaloids and even the acyl portions of cephalotaxus ester alkaloids.
