Phosphorylation of Arabidopsis NRT1.1 regulates plant stomatal aperture and drought resistance in low nitrate condition
Our study provides several lines of evidence to demonstrate that the phosphorylation of NRT1.1 at T101 contributes to the drought tolerance under LN condition by reducing the influx of nitrate and potassium into the cytoplasm, attenuating membrane depolarization and thereby inducing stomatal closure. This finding identified a novel drought resistance mechanism enabled by post-transcriptional regulation of plasma membrane transporter.
