In Arabidopsis the plasma membrane nitrate transceptor (transporter/receptor) NRT1.1 governs many physiological and developmental responses to nitrate. Point mutations in two key residues of the transceptor differentially affect several of the NRT1.1-dependent responses to nitrate, suggesting that NRT1.1 activates independent signalling pathways.
