Locus name | At5g67300 |
Alias | AtMYBR1/AtMYB44 |
Organism | Arabidopsis thaliana |
Taxonomic identifier | [NCBI] |
Function category | Transcription regulation:MYB |
Effect for Senescence | delay |
Gene Description | The transcription factor AtMYBR1 (MYB44) is a member of the MYB family of transcription factors and is expressed throughout the plant life cycle and especially in senescing and wounded leaves. |
Evidence | Genetic evidence:transgene [Ref 1] |

When MYBR1 was over-expressed under the control of the constitutive 35S promoter in Arabidopsis thaliana (OxMYBR1), leaf senescence was delayed. In contrast loss-of-function mybr1 plants showed more rapid chlorophyll loss and senescence. | |
