The transcription factors VaERF16 and VaMYB306 interact to enhance resistance of grapevine to Botrytis cinerea infection.

ABSTRACT: Botrytis cinerea is a fungus that infects cultivated grape (Vitis vinifera); the identification and characterization of resistance mechanisms in the host is of great importance for the grape industry. Here, we report that a transcription factor in the ethylene-responsive factor (ERF) family (VaERF16) from Chinese wild grape (Vitis amurensis 'Shuang You') is expressed during B. cinerea infection and in response to treatments with the hormones ethylene and methyl jasmonate. Heterologous overexpression of VaERF16 in Arabidopsis thaliana substantially enhanced resistance to B. cinerea and the bacterium Pseudomonas syringae DC3000 via the salicylic acid and jasmonate/ethylene signalling pathways. Yeast two-hybrid, bimolecular fluorescence complementation, and co-immunoprecipitation assays indic
