Plants develop strategies to recycle phosphorus so that all organs receive adequate amount of phosphorus, especially new growing organs. To evaluate the metabolic adaptation of rice plant under phosphorus deficient condition, we selected several genes relating phosphorus utilizing efficiency in the cell. Phosphoenolpyruvate carboxylase, triose phosphate translocator, phosphoenolpyruvate/inorganic phosphate translocator (PPT), pyruvate kinase, NAD dependent glyceraldehydes-3-phosphate dehydrogenase, NADP dependent glyceraldehydes-3-phosphate dehydrogenase, were selected because of their important role in the phosphorus utilization in the cell and 2 consisting proposed bypass pathway to save phosphate. Most dramatic change was observed in the expression level of PPT (which tranport phosphoenolpyruvate (PEP) in the cytosol to chloroplast), thus we consider that PEP may play an important role in maintaining carbon metabolism under phosphate deficient condition.
