Chl1 functions as a nitrate sensor
WebApr 22, 2014 · In contrast to NRT2.1 response, we found that the nitrate response of AFB3 and NAC4 was altered in the chl1–5 (Fig. 1D and 1G) and in the chl1–9 mutant (Fig. 1E and 1H).This result suggests that nitrate induction of AFB3 and NAC4 depends on the nitrate transport function of NRT1.1. Furthermore, nitrate response of AFB3 and NAC4 was … 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 …
