Abstract
Elevated atmospheric CO2 concentration (e[CO2]) and soil water deficits have substantial effect on stomatal morphology and movement that regulate plant water relations and plant growth. e[CO2] could alleviate the impact of drought stress, thus contributing to crop yield. Xylem-borne abscisic acid (ABA) plays a crucial role in regulating stomatal aperture serving as first line of defence against drought; whereas e[CO2] may disrupt this fundamental drought adaptation mechanism by delaying the stomatal response to soil drying. We review the state-of-the-art knowledge on stomatal response to drought stress at e[CO2] and discuss the role of ABA in mediating these responses.Entities:
