General Information	Comment	Organism
physiological function	a double mutant lacking both isoforms Ppc1/Ppc2 exhibits a severe growth-arrest phenotype. The Ppc1/Ppc2 mutant accumulates more starch and sucrose than wild-type plants when seedlings are grown under normal conditions. Decreased PEPC activity in the mutant greatly reduces the synthesis of malate and citrate and severely suppresses ammonium assimilation. Nitrate levels in the double mutant are significantly lower than those in wild-type plants due to the suppression of ammonium assimilation. Starch and sucrose accumulation can be prevented and nitrate levels can be maintained by supplying the Ppc1/Ppc2 mutant with exogenous malate and glutamate	Arabidopsis thaliana
