Webment. 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). Previous studies ...
