Arabidopsis thaliana	PNPase expression is repressed by the response regulator phosphorus starvation response1 under phosphorus limitation	down

General Information

General Information	Comment	Organism
physiological function	PNPase regulates chloroplast transcript accumulation in response to phosphorus starvation, the activity of the chloroplast PNPase is involved in plant acclimation to phosphorus availability and may help maintain an appropriate balance of phosphorus metabolites even under normal growth conditions	Arabidopsis thaliana
