Phy­to­plas­mas are ­unculturable wall ­less bac­te­ria ­involved in ­many ­plant dis­eas­es; in par­tic­u­lar Fla­ves­cence ­dorée rep­re­sents a ­severe ­threat to vit­i­cul­ture, ­because of its epidemic behavior in field. ­Here we ­present the appli­ca­tion of the LDR tech­nique, asso­ciat­ed ­with hybrid­isa­tion on uni­ver­sal ­arrays, as a ­quick and reli­able ­tool for ­plant qua­ran­tine pro­ce­dures and man­da­to­ry meas­ures, in ­order to dis­tin­guish ­between dif­fer­ent ­phytoplasmas’ ­induced infec­tions, com­pared to clas­si­cal pro­to­cols in use, par­tic­u­lar­ly PCR - ­RFLP ­assays.
