Locus name | AT4G16110 |
Alias | ARR2 |
Organism | Arabidopsis thaliana |
Taxonomic identifier | [NCBI] |
Function category | Hormone response pathway:CK |
Effect for Senescence | delay |
Gene Description | Encodes a pollen-specific transcription factor involved in the expression of nuclear genes for components of mitochondrial complex I in Arabidopsis. Acts in concert with other type-B ARRs in the cytokinin signaling pathway. AHK3 mediates cytokinin-induced phosphorylation of ARR2 on the Asp-80 residue. This phosphorylation plays a positive role of ARR2 in cytokinin-mediated control of leaf longevity. |
Evidence | Molecular evidence [Ref 1]; Genetic evidence:transgene [Ref 2] |
