Geneticist Amanda Garris and plant pathologist Lance Cadle-Davidson examine differences in growth and development in two plants in the USDA Cold Hardy Grape Collection. A genetic difference caused the plant on the left (with yellow leaves) to go dormant before the one on the right, a natural variation that could be used in future grape improvement.
