1.1.1.284 gene Os02g0815500 or Os02G57040, single copy gene Oryza sativa Japonica Group

Protein Variants

EC Number Protein Variants Comment Organism
1.1.1.284 additional information knockout of OsGSNOR (Os02G57040), using the CRISPR/Cas9 system. The root growth in two OsGSNOR knockout lines (Osgsnor-1 and Osgsnor-2) is significantly more sensitive to NH4+ than in wild-type. Compared with the wild-type, the root K+ content in Osgsnor knockout lines is lower under NH4+ Oryza sativa Japonica Group

1.1.1.284 malfunction increased NO content is involved in NH4+ inhibition of root growth. GSNOR overexpression improves root tolerance to NH4+, phenotypes, overview. Loss of GSNOR further induces NO accumulation, increases SNO1/SOS4 activity, and reduces K+ levels in root tissue, enhancing root growth sensitivity to NH4+. NO contributes to NH4+-inhibited K+ absorption in Arabidopsis at least partly via enhanced SNO1/SOS4 activity. The NH4+-induced GSNOR protein accumulation is abolished in the VTC1- (vitamin C1) defective mutant vtc1-1, which is hypersensititive to NH4+ toxicity. GSNOR overexpression enhances vtc1-1 root tolerance to NH4+ Arabidopsis thaliana

1.1.1.284 physiological function induction of S-nitrosoglutathione reductase protects root growth from ammonium toxicity by regulating potassium homeostasis in Arabidopsis thaliana. GSNOR negatively regulates ammonium-mediated NO accumulation and K+ imbalance, Arabidopsis thaliana GSNOR is a master regulator of the intracellular NO level Arabidopsis thaliana
