The effects of exogenously applied gibberellic acid (GA (3)) or brassinolide (BL) on the H (+)-pumps and aquaporin in the vacuolar membrane of rice seedling leaf sheath were investigated.

Then, we investigated the effects of salt and water stresses (150 mM NaCl, 300 mM mannitol and 20% polyethylene glycol) and phytohormones (gibberellic acid, abscisic acid and brassinolide) on the mRNA and protein levels of aquaporins in the plasma membrane (RsPIP1-1, 1-2, 1-3, 2-1, 2-2 and 2-3) and vacuolar membrane (RsTIP1-1 and 2-1).

The significance of promoter regions for an abscisic acid- and gibberellic acid-induced gene expression could be restricted to a region between -1450 and -1112 upstream of the transcription start point by transient transformation of a bicistronic vector into tobacco protoplasts.

The same was true for the application of gibberellic acid (GA) and abscisic acid (ABA).

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.
