Sustainability of Michigan grape industry is limited by climatic constraints, primarily freezing temperatures. In 2014-15, the two “polar vortex” caused $8 million losses to Michigan vineyards, causing a crop reduction up to 70% for major varieties grown in the state. Therefore, there is a need to develop novel strategies to increase freezing tolerance (FT) of grapevines. This project investigated the molecular, biochemical, and physiological mechanisms underpinning the acquisition of FT. Ultimately, the findings from this research will enhance the economic and environmental sustainability of grape production in Michigan and the East of US.
