Gibberellic acid appeared to modulate the activity of the H (+)-translocating ATPase located at the plasma membrane of the mesophyll cells.

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.
Antibodies against mung bean H (+)-PPase, the B subunit of V-ATPase, and radish tonoplast intrinsic protein (TIP) cross-reacted with the vacuolar membrane proteins of rice seedling leaf sheath.

Analysis of the expression of FsA1 transcripts during stratification shows an increase in the presence of gibberellic acid (GA (3)), a treatment that proved to be efficient in breaking dormancy and increasing germination percentages of these seeds, while the addition of paclobutrazol, a well-known GA biosynthesis inhibitor, greatly reduces the expression of the clone.

Among these was a GA-responsive mRNA encoding the 16-kD hydrophobic subunit c of the V (0) membrane sector of vacuolar H (+)-translocating ATPases (V-ATPase), which we termed LVA-P1.

Under conditions of total inhibition of nitrate-sensitive ATPase of the tonoplast, the vesicles of the fraction obtained exhibited the ATP-dependent accumulation of Ca2+.
It was inhibited to various extents by Na3VO4, dicyclohexyl carbodiimide (DCCD) and phytohormones--gibberellic acid (GA3), abscisic acid (ABA) and indoleacetic acid (IAA), whereas kinetin rendered a stimulating effect.

Effects of indoleacetic, abscisic, gibberellic acids and kinetin on the hydrolytic activity of the proton pumps H+-ATPase (EC 3.6.1.3) and H+-pyrophosphatase (EC 3.6.1.1) under non-optimal ionic conditions were studied in tonoplasts isolated from stored roots of red beet (Beta vulgaris L. cv.

Effects of phytohormones gibberellic acid (GA) and abscisic acid (ABA) on the ATP-dependent transmembrane transport of protons were studied in plasma membrane vesicles (PMVs) from non-dormant potato tubers.
It is concluded that the ATP-induced quenching of the AO fluorescence resulted from the accumulation of protons in PMVs due to the function of the plasma membrane-bound H+-ATPase.

We further showed that ACPK1 is localized in both plasma membranes and chloroplasts/plastids and positively regulates plasma membrane H+-ATPase in vitro, suggesting that ACPK1 may be involved in the ABA-signaling pathway.
The other phytohormones such as auxin indoleacetic acid, gibberellic acid, synthetic cytokinin N-benzyl-6-aminopurine, and brassinolide are also ineffective in this ACPK1 stimulation.

The abolishment of these responses by p-chloromercuriphenylsulfonic acid and experiments on proton flux suggest that both factors (cell turgor and hormones) are modulating the H (+) ATPase plasmalemma activity.
