General Information

General Information	Comment	Organism
physiological function	enzyme exhibits sn-2 acyltransferase and phosphatase activities with dicarboxylic acid-CoA as acyl donor. When non-substituted acyl-CoA is used as acyl donor, the rate of acylation is considerably lower and phosphatase activity is not manifested. RNA interference-mediated down-regulation of all isoform GPAT4 homologues under the control of the napin promoter causes abnormal development of several reproductive organs and reduced seed set. Both pollen grains and developing embryo sacs are affected. The gpat4 mature embryos show decreased cutin content and altered monomer composition, the defect further affects the oil body morphology, oil content, and fatty acid composition in gpat4 seeds	Brassica napus
