- Key message
- The expression of Osj10gBTF3 was primarily constitutive and generally modulated by salt, high temperature and exogenous phytohormone stress
- Inhibition of a basal transcription factor 3-like gene Osj10gBTF3 in rice results in significant plant miniaturization and typical pollen abortion
- Our demonstration of the important role of Osj10gBTF3 in rice growth and development provides new insights showing that more complex regulatory functions are associated with BTF3 in plants
- Knockout of Osj10gBTF3 affects pollen and chloroplast development and significantly reduces the accumulation of fertility-related chloroplast protein OsPPR676
- Interestingly, the interaction between OsHSP82 and OsPPR676 is only found in the cytoplasm, while the interaction between Osj10gBTF3 and OsPPR676 also occurs inside the chloroplast
- Further investigation indicates that Osj10gBTF3 enters the chloroplast stroma possibly through the inner chloroplast membrane channel protein Tic110 and then recruits OsCpn60 for the folding or assembly of OsPPR676
- Our results reveal a chaperone role of Osj10gBTF3 in chloroplast import different from Hsp90 and provide a link between chloroplast transport and pollen development in rice
- Connection
- OsBTF3~Osj10gBTF3, OsPPR676~OsATP4, A Plastid-Localized Pentatricopeptide Repeat Protein is Required for Both Pollen Development and Plant Growth in Rice, In this study, OsPPR676 was confirmed to be an interacted protein with Osj10gBTF3, β-subunit of nascent polypeptide-associated complex (β-NAC), by bimolecular fluorescence complementation assays, indicating that both proteins are probably involved in the same regulatory pathway of pollen development
- Hsp90~rHsp90~OSGrp94, OsBTF3~Osj10gBTF3, Osj10gBTF3-Mediated Import of Chloroplast Protein Is Essential for Pollen Development in Rice, Here, we demonstrated that Osj10gBTF3, a NAC protein, regulates pollen and chloroplast development in rice by coordinating with a Hsp90 family chaperone OsHSP82 to mediate chloroplast import
