Dynamic control of plant water use using designed ABA receptor agonists (Science)

ABA is synthesized in response to water stress and promotes stomatal closure, thus decreasing transpiration. Crop yields can be increased by controlling transpiration early in the growing season, ensuring that soil water resources persist through the seed-set period. Building upon earlier studies, Vaidya,…

ABA-mediated regulation of stomatal density is OST1-independent (Plant Direct)

Stomata are not only important for CO2 uptake, but are also important in limiting water loss when the water availability is running low. Stress hormone ABA activates protein kinase OPEN STOMATA 1 (OST1) leading to opening of ion channels, water efflux and stomatal closure. Increased levels of ABA decrease…
