These experiments explored intraspecific variation in response to elevated CO, Angiosperms are able to respond rapidly to the first sign of dry conditions, a decrease in air humidity, more accurately described as an increase in the vapor pressure deficit between the leaf and the atmosphere (VPD), by abscisic acid (ABA)-mediated stomatal closure. Commonly called kowhai, these shrubs and small trees thrive in mild climates, such as those found along the California coast. The root system of the kowhai tree has the ability to fix nitrogen in nutrient deficient soil. The genes underlying this response offer valuable candidates for targeted selection of crop varieties with improved drought tolerance, a critical goal for current plant breeding programs, to maximize crop production in drier and increasingly marginalized environments, and meet the demands of a growing population in the face of a changing climate.
