Protein Variants

EC Number Protein Variants Comment Organism
7.3.2.4 additional information isolation of three high nitrogen insensitive mutants, belonging to three genetic loci and related to single and recessive mutations, that display reduced downregulation of both NRT2.1 expression and high-affinity NO3- influx under repressive conditions. associated with an almost complete suppression of systemic repression of pNRT2.1 activity by high N status of the whole plant. The three hni mutants define a class of N signaling mutants specifically impaired in the systemic feedback repression of root NO3- uptake, molecular effects of the mutations and phenotypes, detailed overview. pNRT2.1::LUC is a good marker for NRT2.1 expression Arabidopsis thaliana
