Grapevine genetics and plant water loss

A study of the progeny from a cross between Syrah and Grenache, two grapevine cultivars grown worldwide, identified regions in the grapevine genome that breeding programs could target to reduce nightly transpiration rates and water loss while maintaining the plant’s growth efficiency, findings that may have implications for cultivating plants with high water-use efficiency for use in drought-prone regions. - Read at PNAS.org
