Abscisic acid and stomatal closure

Stomatal closure by fast abscisic acid signaling is mediated by the guard cell anion channel slah3 and the receptor rcar1 sci signal 4: ra32 the arabidopsis sugar-insensitive mutants sis4 and sis5 are defective in abscisic acid synthesis and response. A bifurcating pathway directs abscisic acid effects on stomatal closure and opening in arabidopsis girish mishra, wenhua zhang, fan deng, jian zhao, xuemin wang. Abscisic acid (aba) is a plant hormone the aba-induced stomatal closure reduces transpiration (evaporation of water out of the stomata), thus preventing further water loss from the leaves in times of low water availability.

  • An abscisic acid-independent oxylipin pathway controls stomatal closure and immune defense in arabidopsis [jean-luc montillet, nathalie leonhardt, samuel mondy, sylvain tranchimand, dominique rumeau, marie boudsocq, ana victoria garcia.

  • S-type anion channels are direct targets of abscisic acid (aba) signaling and contribute to chloride and nitrate release from guard cells, which in turn initiates stomatal closure.
  • Abscisic acid owes its names to its role in the abscission of plant leaves the aba-induced stomatal closure reduces transpiration, thus preventing further water loss from the leaves in times of low water availability[citation needed.
  • The regulatory domain of srk2e/ost1/snrk26 interacts with abi1 and integrates abscisic acid (aba) and osmotic stress signals controlling stomatal closure in arabidopsis.

Abscisic acid applications decrease stomatal conductance and delay wilting in drought-stressed chrysanthemums prolonged stomatal closure and reduced transpiration can lead to heat stress under high exogenous abscisic acid application effects on stomatal closure, water.
