Calcium-induced calcium release mediated by a voltage-activated cation channel in vacuolar vesicles from red beet.

Abstract

Little is known about the mechanisms underlying calcium-induced Ca2+ release (CICR) in plants. The slow-activating vacuolar (SV) channel is both permeable to, and activated by Ca2+, and is therefore a prime candidate for a role in CICR. Cytosol-side-out vacuolar membrane vesicles loaded with 45Ca2+ showed voltage- and Ca(2+)-dependent Ca2+ release, which was sensitive to the SV channel modulators DIDS, protein phosphatase 2B and calmodulin. Significantly, voltage-dependent Ca2+ release strongly depended on cytoplasmic Ca2+ concentrations. The results support the notion that CICR occurs in plant cells and that the process can be catalysed by the SV channel on the vacuolar membrane.
