Recently, a study conducted by researchers at the University of Florence in Italy has uncovered a key role for the ethylene hormone in grapevine tolerance to cold stress. The research demonstrates that ethylene is transcriptionally activated by cold stress in the grapevine, leading to increased tolerance of cold temperatures. This finding could provide new insight into how grapevines can resist cold-related damage, and potentially increase the harvest of wine grapes during cooler seasons. The results of this research could have a significant impact on the wine industry, as it could lead to more reliable harvests and higher quality wines.
