The grape berry provides a model for investigating the physiology of non-climacteric fruits. Increased K+ accumulation in the berry has a strong negative impact on fruit acidity (and quality). In maturing berries, we identified a K+ channel from the Shaker family, VvK1.2, and two CBL-interacting pro...
