| Locus name | AT1G64520 |
| Alias | RPN12a | | Organism | Arabidopsis thaliana | | Taxonomic identifier | [NCBI] | | Function category | | | Effect for Senescence | delay | | Gene Description | The RPN12a proteasome subunit is essential for the multiple hormonal homeostasis controlling the progression of leaf senescence.Such enhanced aptitude of plant cells for survival in rpn12a contrasts with reports on animals, where 26S proteasome mutants generally show an accelerated cell death phenotype.a rpn12a knock-out had exacerbated 20S and impaired 26S activities. The altered proteasomal activity led to a pleiotropic phenotype affecting both the vegetative growth and reproductive phase of the plant, including a striking repression of leaf senescence associate cell-death. | | Evidence | Genetic evidence [Ref 1] | | References | 1: |
