Project description:Three grapevines cultivars (Merlot, Cabernet-Sauvignon and Ugni Blanc) were infected by E. lata. The expression profiles of the wood part near the infection point were determined for both infected and non infected plant for each cultivars with Nimblegen microarrays vitis. Three plants were used for biological replicates. Comparisons between infected and non infected conditions allow, for each cultivars, the identifcation of genes which the expression is modified by E. lata.
