16821193 Cerana M, Bonza MC, Harris R, Sanders D, De Michelis MI: Abscisic acid stimulates the expression of two isoforms of plasma membrane Ca2+-ATPase in Arabidopsis thaliana seedlings. Plant Biol. 2006 Sep;8(5):572-8. Epub 2006 Jul 5.

In this article the expression of AT-ACA8, AT-ACA9, and of AT-ACA10, a third isoform of Ca (2+)-ATPase closely related to PM Ca (2+)-ATPases, was analysed and the effect of the hormone abscisic acid (ABA) on the expression level of PM Ca (2+)-ATPase specific transcripts was investigated.

Plant Physiol. 2004 May;135(1):231-43.

Using experiments employing combined voltage clamping, continuous measurement of extracellular pH, we examined whether plasma membrane H (+)-ATPases could also be involved in the depolarization.

Light activates proton (H (+))-ATPases in guard cells, to drive hyperpolarization of the plasma membrane to initiate stomatal opening, allowing diffusion of ambient CO (2) to photosynthetic tissues.

Vacuolar ATPases help in maintaining the pH of the vacuoles and thereby play a crucial role in the functioning of vacuolar sodium-proton antiporter.

Identifying their direct in vivo targets of regulation, which may include H (+)-ATPases, ion channels, 14-3-3 proteins and transcription factors, will logically be the next major challenge.
