[The function of F-box protein in plant growth and development].
Ubiquitin-mediated proteolysis is involved in many biological processes in eukaryotes. SCF complex is a very important ubiquitin E3 ligase which has been exploited very well in plants. F-box protein characterized by an F-box motif is a subunit of SCF complex, which works as determinant in substrate recognition. Currently, many F-box proteins have been identified in plants which are involving in hormone (e.g., ethylene, auxin, gibberellin and jasmonate ) signal transduction and biological processes, such as self-incompatibility and floral development. F-box proteins may also participate stress response in plants. Recent study suggested that the Arabidopsis F-box protein TIR1 is an auxin receptor. Therefore, F-box protein mediated proteolysis may be an important gene expression mechanism in plants.
