Chl1 functions as a nitrate sensor in plants
WebJun 1, 2024 · To date, the versatile roles of nitrate transporter NRT1.1 in nitrate transport, sensing, and signalling have been well recognized in plants [11 ]. In Arabidopsis, AtNRT1.1/AtNPF6.3/CHL1 was identified as a dual-affinity nitrate transporter and its affinity switch was modulated by the phosphorylation status at T101 residue [ 12, 13 ].

WebSep 18, 2009 · The primary nitrate response defect in the chl1-5 mutant could be due to either reduced nitrate uptake into the plant or direct involvement of CHL1 as a nitrate sensor. To determine whether the … WebNov 24, 2024 · The nitrate transporter NRT1.1 is a dual-affinity nitrate transceptor controlling the primary nitrate response (nitrate signaling), in which expressions of nitrate assimilation genes and nitrate transporter genes are induced rapidly by nitrate treatments (Ho et al., 2009). NRT1.1 facilitates not only nitrate uptake but also auxin transport.
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 … WebLiving organisms sense and respond to changes in nutrient availability to cope with diverse environmental conditions. Nitrate (NO 3 −) is the main source of nitrogen for plants and is a major component in fertilizer.Unraveling the molecular basis of nitrate sensing and regulation of nitrate uptake should enable the development of strategies to increase the …
WebFeb 12, 2024 · During the last two decades, great progress has been made in identifying transporters for mineral elements in different plant species, especially in model plants, such as Arabidopsis and rice. For a representative example of macronutrients (i.e. those required in large amounts), a major transporter responsible for nitrate uptake, CHL1, was ...

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 …
WebSep 2, 2015 · More importantly, the single amino acid substitution mutant chl1-9 was defective in nitrate uptake, but showed a normal nitrate response, indicating that the nitrate uptake and nitrate response are separate processes, and NPF6.3 functions as a nitrate sensor and triggers nitrate-specific signaling pathways in response to nitrate availability … graduation cap and gown ucfWebOverexpression of Rice Genes OsNRT1.1A and OsNRT1.1B Restores Chlorate Uptake and NRT2.1/NAR2.1 Expression in Arabidopsis thaliana chl1-5 Mutant chimney repair rome gaWebJan 25, 2024 · In 2009, a milestone work was shown that the dual-affinity nitrate transporter, AtNRT1.1, can function as a pivotal nitrate sensor regulating an impressive range of responses to nitrate, and it is also shown that the phosphorylation state of AtNRT1.1 is responsible for the perception of external nitrate and triggering downstream … chimney repair quad citiesWebOct 1, 2010 · Nitrate transporter CHL1 also functions a nitrate sensor (transceptor).
