Grapevine cell early activation of specific responses to DIMEB, a resveratrol elicitor.

ABSTRACT:

Background

In response to pathogen attack, grapevine synthesizes phytoalexins belonging to the family of stilbenes. Grapevine cell cultures represent a good model system for studying the basic mechanisms of plant response to biotic and abiotic elicitors. Among these, modified beta-cyclodextrins seem to act as true elicitors inducing strong production of the stilbene resveratrol.

Results

The transcriptome changes of Vitis riparia x Vitis berlandieri grapevine cells in response to the modified beta-cyclodextrin, DIMEB, were analyzed 2 and 6 h after treatment using a suppression subtractive hybridization experiment and a microarray analysis respectively. At both time points, we identified a specific set of induced genes belonging to the general phenylpropanoid metabolism, inclu
