In higher plants, protein ubiquitination plays an essential role in many biological processes, including hormone signaling, photomorphogenesis, and pathogen defense. However, the roles of protein ubiquitination in the reproductive process are not clear. In this study, we identified four plant-specific RING-finger genes designated Aberrant Pollen Development 1 (APD1) to APD4, as regulators of pollen mitosis II (PMII) in Arabidopsis thaliana (L.). The apd1 apd2 double mutant showed a significantly increased percentage of bicellular-like pollen at the mature pollen stage. Further downregulation of the APD3 and APD4 transcripts in apd1 apd2 by RNA interference (RNAi) resulted in more severe abnormal bicellular-like pollen phenotypes than in apd1 apd2, suggesting that cell division was defective in male gametogenesis. All of the four genes were expressed in multiple stages at different levels during male gametophyte development. Confocal analysis using green florescence fusion proteins (GFP) GFP-APD1 and GFP-APD2 showed that APDs are associated with intracellular membranes. Furthermore, APD2 had E2-dependent E3 ligase activity in vitro, and five APD2-interacting proteins were identified. Our results suggest that these four genes may be involved, redundantly, in regulating the PMII process during male gametogenesis."xsd:string |
