Calcium release from the endoplasmic reticulum of higher plants elicited by the NADP metabolite nicotinic acid adenine dinucleotide phosphate.

Abstract:

Higher plants share with animals a responsiveness to the Ca(2+) mobilizing agents inositol 1,4,5-trisphosphate (InsP(3)) and cyclic ADP-ribose (cADPR). In this study, by using a vesicular (45)Ca(2+) flux assay, we demonstrate that microsomal vesicles from red beet and cauliflower also respond to nicotinic acid adenine dinucleotide phosphate (NAADP), a Ca(2+)-releasing molecule recently described in marine invertebrates. NAADP potently mobilizes Ca(2+) with a K(1/2) = 96 nM from microsomes of ...
