Locus name | AT3G48100 |
Alias | ARR5 |
Organism | Arabidopsis thaliana |
Taxonomic identifier | [NCBI] |
Function category | Hormone response pathway:CK |
Effect for Senescence | delay |
Gene Description | Encodes a transcription repressor that mediates a negative feedback loop in cytokinin signalling. ARR5 expression is upregulated by Class I KNOX genes. Arr5 protein is stabilized by cytokinin in a two-component phosphorelay.Downregulated in senescent leaves. |
Evidence | Genetic evidence:Mutant [Ref 1]; Molecular evidence: microarray data [Ref 2] |
