Isoforms of plasma membrane H(+)-ATPase in rice root and shoot are differentially induced by starvation and resupply of NO₃⁻ or NH₄+.


The goal of this study was to evaluate the effects of nitrogen starvation and resupply in 10 PM H+-ATPase isoforms and the expression of NO₃⁻ and NH₄+ transporters in rice. The net uptake of both forms of NO₃⁻-N or NH₄+-N was increased with its resupply. Resupply of NO₃⁻ resulted in induction of the following PM H+-ATPase isoforms, OsA1, OsA2, OsA5 and OsA7… (More)
