Gene Details:

• MSU gene ID: LOC_Os01g24880
• RAPdb gene ID: Os01g0350900
• Gene Symbol: IPI1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• IPI1 promotes the degradation of IPA1 in panicles while it stabilizes IPA1 in shoot apexes.
• Moreover, IPI1 could ubiquitinate IPA1-mediated complex with different polyubiquitin chains, adding K48-linked polyubiquitin chains in panicles and K63-linked polyubiquitin chains in the shoot apex.
• Consistent with these findings, the IPI1 loss-of-function mutants showed markedly altered plant architecture, including more tillers, enlarged panicles, and increased yield per plant.
• These results demonstrate that IPI1 affects plant architecture through precisely tuning IPA1 protein levels in different tissues in rice, and provide new insight into the tissue-specific regulation of plant architecture and important genetic resources for molecular breeding applications.
