Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G27320 AHK3 cytokinin double mutant Encodes a putative plasma membrane-bound hybrid histidine kinase and cytokinin sensor that is expressed within the female gametophyte, a cytokinin receptor that controls cytokinin-mediated leaf longevity through a specific phosphorylation of the response regulator, ARR2
AT5G35750 AHK2 cytokinin double mutant osmosensor activity, protein histidine kinase activity, response to water deprivation, response to osmotic stress, response to salt stress, cytokinin receptor activity, response to abscisic acid stimulus, regulation of seed germination, regulation of chlorophyll catabolic process, regulation of shoot development
