Nitrate(N03^(-))is one primary nitrogen source for plants and also serves as a signal to modulate plant growth and development.NRT1.1(also called CHL1 or NPF6.3)is an essential nitrate transporter resident at the plasma membrane(Ho et al.,2009).Apart from the role in nitrate uptake,NRT1.1 also regulates a set.of nitrate-responsive genes,functioning as a nitrate sensor,namely transceptor(Ho et al.,2009;Bouguyon et al.,2015).
