WebNitrate Transporter 1.1 (NRT1.1) is a nitrate transporter and sensor that modulates plant metabolism and growth. ... When the CO mutation was introduced into chl1-5 plants, the double mutant had delayed flowering time, and the CO transcription levels did not change in the chl1-5 plants. ... These results indicate that the CO-dependent ... WebNitrogen (N) deficiency often causes early leaf senescence, but the underlying molecular mechanism remains unclear. This study identifies Growth, Development and Splicing 1 (GDS1) as a key regulator of nitrate signaling and N-deficiency-induced early leaf senescence in Arabidopsis. GDS1 represses N-deficiency-induced early leaf senescence …
WebJul 1, 2024 · The identification of the first nitrate transporter, AtNRT1.1 (CHL1/AtNPF6.3), in Arabidopsis represents an important milestone on the road to understanding the molecular basis of nitrate use in plants ( Tsay et al., 1993 ). By performing large-scale screening of an Arabidopsis T-DNA mutant library using chlorate, a toxic analog of nitrate ... WebJun 4, 2024 · We also included chl1-9 into the study, a mutant of NRT1.1 in which NRT1.1 lost its nitrate uptake ability but retained its nitrate sensor function (Ho et al., 2009). On the 7N medium, wild-type roots made an average of 300-degree right turn after 5 days on horizontal plates, which was significantly enhanced on 0N medium ( Figures 5A,B ), as ...

The high-affinity nitrate transporter (CHL1) functions as an ion sensor in higher. red lion hvacWebApr 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 … red lion hubWebOct 1, 2010 · Research highlights. Nitrate transporter CHL1 also functions a nitrate sensor (transceptor). Phosphorylation statuses of CHL1 T101 residue are regulated by external nitrate concentration in the soil. Phosphorylation statuses of T101 can switch the affinities of CHL1 transport activity, and induce different levels of nitrate regulated … richard man fai leeWebDec 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.
