Based on experimental data obtained in earlier studies on membrane permeabilities of abscisic acid (ABA) for cortex and stele cells of roots and on measured compartmental pH shifts after onset or release of different types of soil-borne stresses, a b

Abscisic acid (ABA) is a stress signal that is transported from the root system to leaves, and induces stomatal closure before water relations of the leaves are affected by soil drying. Xylem vessels are in direct contact with the leaf apoplasm, the

Jasmonic acid (JA) permeates the plasma membrane of mesophyll cells by diffusion as the lipophilic undissociated JAH molecule probably without the participation of a saturable uptake component. The mesophyll plasma membrane is nearly impermeable to t

Summary When leaf disks of Valerianella locusta were incubated with 1O -2 mol m -3 of the growth retardant tetcyclacis (an inhibitor of cytochrome P 450 dependent monoxygenases) oxidative ABA degradation to phaseic acid was inhibited, whereas formati

Uptake of 3H-labelled (±)-abscisic acid (ABA) into isolated barley (Hordeum vulgare L.) epidermal cell protoplasts (ECP) was followed over a range of pH values and ABA concentrations. The present results show that ABA uptake is not always linearly c
