GAR2 — Arabidopsis thaliana

Summary

AT4G24210, also known as GAR2, SLEEPY1 or SLY1 in Arabidopsis thaliana, encodes an F-box protein of the SNE/GID2 family that is a component of the SCF ubiquitin ligase complex. The gene is associated with gibberellin-mediated signalling and the regulation of gibberellic acid signalling pathways, as well as SCF complex assembly and the transport of the GA-GID1 complex to the nucleus. GAR2 is linked to numerous traits including seed germination, dwarf phenotype, delayed flowering, floral organ defects, reduced seed number and fertility, and altered gibberellin levels and responsiveness. It is also associated with cadmium sensitivity, copper concentration, nitrate content, seed protein content, and responses to light and phosphorus. The gene product localises to the SCF complex, ubiquitin ligase complex, nucleolus, chloroplast envelope, and endoplasmic reticulum.
