General Information

General Information Comment Organism
evolution NRT1.5 belongs to the NRT1 family of transporters Arabidopsis thaliana
malfunction functional disruption of NRT1.5 enhances tolerance to salt, drought and cadmium stresses, also nitrate as well as Na+ and Cd2+ levels are significantly increased in nrt1.5 roots. Genes including NHX1, SOS1, P5CS1, RD29A, AtPCS1 and NRT1.8, important in stress response pathways, are steadily upregulated in nrt1.5 mutant plants Arabidopsis thaliana
metabolism nitrate reallocation to roots might be a common response to stresses and is coordinately regulated by NRT1.8 and NRT1.5 genes, overview Arabidopsis thaliana
physiological function NRT1.5 functions to mediate nitrate reallocation to roots, stress-responsive gene expression and metabolism, and consequently salt, drought and Cd2+ tolerance. NRT1.5 is involved in nitrate allocation to roots and the consequent tolerance to several stresses, in a mechanism probably shared with NRT1.8. NRT1.5 works together with NRT1.8 to fine-tune nitrate long-distance transport from roots to shoots Arabidopsis thaliana
