As a step toward understanding the aquaporin function in plants under various environmental stimuli, the expressions of a gene family encoding 13 PIPs in Arabidopsis thaliana under various abiotic stress conditions including drought, cold, and high salinity, or abscisic acid (ABA) treatment were investigated by a quantitative real-time reverse transcription-PCR analysis.

It is suggested that this involves an aquaporin as sensor, and perhaps also as responder; deformation of the aquaporin may render it ion-permeable, or, alternatively, the deformed aquaporin may signal to an associated ion channel, activating it.

Meanwhile, we observed a significant increase in the endogenous abscisic acid (ABA) level in upland rice but not in lowland rice under water deficit.
Aquaporins play a significant role in plant water relations.

Four plant hormones: gibberellic acid (GA3), indole 3-acetic acid (IAA), abscisic acid (ABA)(+/-) and methyl jasmonate (MJ), caused marked changes in the volume of mesophyll protoplasts.
Aquaporins or water channels appear to play an important role in swelling/shrinkage of the protoplasts as indicated by the suppression of volume changes by HgCl2 and reversal by mercaptoethanol.

An aquaporin is the most likely sensor and may also be involved in the signal transduction chain.
Tracer flux experiments in isolated guard cells of Commelina communis L. suggest that the vacuolar ion content is regulated and is reset to a reduced fixed point by abscisic acid (ABA) with no significant change in cytoplasmic content.
