Protein Variants Comment Organism
additional information generation of the ahk5-1 mutant containing a T-DNA insertion in the receiver domain of the AHK5 histidine kinase. The AHK5 mutant is more resistant to salt stress. Two complemented lines, PAHK5-AHK5/ahk5-1-1 and PAHK5-AHK5/ahk5-1-4, are generated by complementation of the ahk5-1 mutant with full-length AHK5 including 3205 bases upstream of the ATG start codon Arabidopsis thaliana

General Information

General Information Comment Organism
malfunction loss of function of AHK5 also confers tolerance to high salinity, suggesting that AHK5 acts to integrate multiple stress responses. The AHK5 mutant is more resistant to salt stress, the insensitivity of the ahk5-1 mutant in response to salinity is caused by loss of AHK5 function Arabidopsis thaliana
physiological function the hybrid histidine kinase Arabidopsis histidine kinase 5 (AHK5) mediates stomatal responses to exogenous and endogenous signals in Arabidopsis thaliana, AHK5 integrates abiotic and biotic stimuli in stomatal guard cells through regulation of H2O2 homeostasis. Role for AHK5 in the regulation of survival following challenge by a hemi-biotrophic bacterium and a necrotrophic fungus, as well as in the growth response to salt stress. AHK5 positively regulates salt sensitivity and contributes to resistance to the bacterium Pseudomonas syringae pv. tomato DC3000 and the fungal pathogen Botrytis cinerea, detailed overview. Function of AHK5 in regulating the production of hormones and redox homeostasis. Enzyme AHK5 functions as a negative regulator of root growth inhibition mediated by abscisic acid/ethylene. AHK5 positively regulates salt-induced root growth inhibition Arabidopsis thaliana
