Emerging Players in the Nitrate Signaling Pathway - Molecular Plant
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. WebJul 19, 2024 · The only nitrate sensor proposed thus far is the dual-affinity nitrate transporter NRT1.1. NRT1.1 triggers nitrate responses and is required for normal expression of nitrate-responsive genes. ... CHL1 functions as a nitrate sensor in plants. Cell. 2009; 138: 1184-1194.

WebOct 2, 2013 · In papers by Wang et al. (1998), Liu et al. (1999), and Liu and Tsay (2003), it was proposed that Arabidopsis thaliana Nitrate Transporter1.1 (AtNRT1.1; CHL1) encodes a dual-affinity nitrate transporter that “plays a major role in high-affinity nitrate uptake.”Here, we evaluate this concept by reexamining the uptake kinetics of Arabidopsis (Arabidopsis … 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 … WebSep 1, 2009 · In this study, analysis of an uptake- and sensing-decoupled mutant showed that the nitrate transporter CHL1 functions as a nitrate sensor.
