Bunch Rot

The influence of fruit zone leaf removal treatments (0, 50, and 100%) on grapevine canopy structure, incidence of bunch rot (Botrytis cinerea Pers.:Fr.), yield components, fruit and wine composition and wine sensory attributes was studied on Vitis vinifera L. 'Optima' and 'Cabernet franc'. The 50 and 100% leaf removal reduced leaf layer number, percent interior leaves and percent interior clusters. Yield was reduced between 29 and 46%. Severity of bunch rot in Optima and incidence and severity for Cabernet franc were reduced by leaf removal. Leaf removal improved colour, aroma and palatability of both Optima and Cabernet franc wines. Key words: Botrytis cinerea, defoliation, canopy management

Sublethal Concentrations

During the infection of grapevine (Vitis vinifera) by the fungus Botrytis cinerea, the concentration of polyamines, which are toxic substances for the phytopathogen, increases in the grape. Nine NRPS genes have been identified in the genome of B. cinerea, yet the function of five of them remains unknown. For this reason, we have studied the expression of the 9 NRPS genes by RT-qPCR in a medium supplemented with sublethal concentrations of three polyamines (1,3-diaminopropane (1,3-DAP), spermidine (SPD), and spermine (SPM)). Our results show that the presence of polyamines in the culture medium triggered the overexpression of the Bcnrps1 gene in the pathogen. Deleting Bcnrps1 did not affect mycelial growth or adaptation to osmotic stress, and we show that its expression is not essential for the cycle of infection of the B. cinerea. However, mutating the Bcnrps1 gene resulted in overexpression of the Bcnrps6 gene, which encodes for the excretion of siderophores of the coprogen family. Moreover, gene deletion has reduced the tolerance of B. cinerea B05.10 to toxic substances such as the polyamine SPD and the fungicide pyrimethanil, and its virulence has increased. Our findings provide new insights into the function of the Bcnrps1 gene and its involvement in the tolerance of B. cinerea against exogenous toxic compounds.
