Metabolomic and cytological approaches to better understand grapevine trunk diseases disorders
Grapevine trunk diseases (GTDs) are devastating diseases involving xylem-inhabiting fungi. Among them, Esca and Botryosphaeria dieback affect vineyards in major worldwide grape-producing areas. The causal fungi alter the woody issues and could produce toxins that disturb the plant physiology, leading to chronic or apolectic leaf symptoms. The unique effective fungicide against these diseases, sodium arsenite, is now prohibited because of toxicity. As GTDs are complex and still partly unknown, the identification of protection strategies remain a deadlock. Global and targeted approaches were therefore conducted to get new information on the impact of the diseases and sodium arsenite treatment…
