ABA homeostasis achieved in the tolerant lines is closely coupled to readjustment in ABA receptors, which enables this line to maintain a favorable WUE and photoassimilate accumulation when challenged by terminal drought.

In the epidermis of Arabidopsis leaves, flavonols specifically accumulate in guard cells with enhanced synthesis in the presence of ethylene, where they lower the levels of reactive oxygen species and reduce the rate of stomatal closure.

ABA biosynthetic enzymes expressed in vascular tissues induce stomatal closure, indicating that long-distance ABA signal transfer from the vascular bundle is likely to be mediated by specific transporters.

In cold- or dehydration-stressed rice plants, up-regulation of genes related to starch degradation, sucrose metabolism, and the glyoxylate cycle results in the accumulation of sugars and with, abscisic acid signaling is inversely related to cytokinin signaling.

An understanding of cavitation and the spread of embolism in plant xylem can be viewed from the perspective of physical models of air seeding, the potential for artifacts to interact with natural variation in xylem structure, and new technologies that could lead to their resolution.

Aquaporins are highly regulated water channels that contribute to the control of water movement at the cell, tissue, and organ levels and, hence, to the overall plant water relations in varying environmental conditions.

Changes in evaporative demand or soil water status affect maize leaf growth in less than 1 h, considerably quicker than their effects on transpiration and leaf water potential, consistent with a hydraulic model.
Leaf shrinkage is a potential driver of leaf hydraulic vulnerability, especially under mild stress, and carries strong ecological implications.
