  <dc:description xmlns:ns0="xml" ns0:lang="en">Botryosphaeriaceae is a fungal family comprising many species involved in  botryosphaeria dieback, a worldwide grapevine trunk disease. Currently, the  interactions between Botryosphaeriaceae species and various grapevine cultivars are  poorly understood and little data is available. This study investigated various life traits  of five isolates belonging to four species of Botryosphaeriaceae found in French  vineyards (Diplodia mutila, Diplodia seriata, Lasiodiplodia viticola and Neofusicoccum  parvum). The two species N. parvum and L. viticola exhibited the highest optimal  growth temperature and the best growth rates. They were also responsible for the  most extensive necrosis and cankers in three Vitis vinifera cultivars (Cabernet  Sauvignon, Merlot and Ugni-Blanc) that differed in susceptibility to botryosphaeria  dieback, and in two genotypes resistant to downy and powdery mildew (RV4 and  RV5). Identification of the extracellular toxins produced by isolates in culture media  showed that the N. parvum isolate had a different metabolite profile from the others,  producing terremutin and salicylic acid derivatives, which are known to be compounds  associated with virulence. In a second step, life traits were associated with  nondestructive monitoring of gene expression involved in the defence mechanisms of  five grapevine cultivars and genotypes after inoculation of wood cuttings with  Botryosphaeriaceae. The transcript analyses were carried out at different times and  were associated with principal component analysis (PCA). Each cultivar presented a  specific transcript signature and several transcripts were correlated either with the size  of necrosis/cankers or with symptom reduction, thus offering useful markers for  breeding or estimating the defence status of plants.</dc:description>
