Comment typeDescription
Catalytic ActivityA phosphatidylcholine + H(2)O = 1,2-diacyl-sn- glycerol + phosphocholine.
Disruption PhenotypeNo visible phenotype under normal growth conditions, but mutant plants accumulates reduced levels of digalactosyldiacylglycerol (DGDG) during phosphate limitation. {ECO:0000269|PubMed:18564386}.
FunctionNon-specific phospholipase C (PLC) which assumes minor PLC activity during inorganic phosphate starvation. Can hydrolyze both phosphatidylcholine (PC) and phosphatidylethanolamine (PE). Required for normal accumulation of digalactosyldiacylglycerol (DGDG) during phosphate limitation and may contribute to the conversion of phospholipids to diacylglycerol, the substrate for galactolipid synthesis. {ECO:0000269|PubMed:18564386}.
InductionSlightly induced by inorganic phosphate deprivation. {ECO:0000269|PubMed:15618226, ECO:0000269|PubMed:18564386}.
SimilarityBelongs to the bacterial phospholipase C family. {ECO:0000305}.
Subcellular LocationCytoplasm, cytosol {ECO:0000269|PubMed:18564386}.
Tissue SpecificitySpecifically expressed in flowers. {ECO:0000269|PubMed:20507939}.
