Chl1 functions as a nitrate sensor
WebSep 18, 2009 · Thus, CHL1 uses dual-affinity binding and a phosphorylation switch to sense a wide range of nitrate concentrations in the soil, thereby functioning as an ion sensor in higher plants. For a video summary of … WebThe genetic analysis above suggested that NRT1.1, as a nitrate sensor, may somehow control the activity of CNGC15, a putative Ca 2+ channel, to couple the nitrate signal with the Ca 2+ second messenger. To perform such a function, NRT1.1 and CNGC15 should be in close proximity in the plasma membrane and may physically interact with each other.

WebDec 18, 2015 · NRT1.1 is a dual-affinity transporter. The Arabidopsis NRT1.1 (CHL1 or NPF6.3) protein is the founding member of the NRT1/PTR family. It was firstly cloned as a gene product that is responsible for chlorate sensitivity in Arabidopsis (Tsay et al., 1993).The NRT1.1 protein contains 12 membrane-spanning segments and confers proton-coupled … 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 ...
