WebK+ and NO3- are the major forms of potassium and nitrogen that are absorbed by the roots of most terrestrial plants. In this study, we observed that the close relationship between NO3- and K+ homeostasis was mediated by nitrate transporter1 (NRT1.1) in Arabidopsis. The nrt1.1 mutants lacking NRT1.1 function showed disturbed K+ uptake and root-to … Webalso serves as a signal to modulate plant growth and develop-ment. 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 ...

WebOct 1, 2010 · This study demonstrated that dual-affinity nitrate transporter CHL1 also functions as a nitrate sensor in plants. Using the sensing and uptake decoupled mutant chl1–9, it was shown that nitrate transport was not required for the sensing function of CHL1. In addition, this work identified a protein kinase CIPK23 involved in the … WebJun 1, 2010 · The phosphorylation status of threonine 101 in CHL1 is regulated by external nitrate concentration and controls transport activity and signaling. When T101 is phosphorylated, CHL1 functions as a high-affinity nitrate transporter and sensor, which supports the low-level primary nitrate response at low nitrate concentrations. bite force of a doberman pinscher
