Gene Details:

• MSU gene ID: LOC_Os02g34410
• RAPdb gene ID: Os02g0548700
• Gene Symbol: OsPUB43
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• CRISPR-Cas9 Mediated Mutation in OsPUB43 Improves Grain Length and Weight in Rice by Promoting Cell Proliferation in Spikelet Hull.
• Scanning electron microscopy analysis reveals that OsPUB43 modulates the grain size mainly by inhibiting cell proliferation in the spikelet hull.
• Phenotypes of large grain are observed in OsPUB43 mutants, whereas overexpression of OsPUB43 results in short grains.
• Collectively, our results indicate that OsPUB43 negatively controls the gain size by modulating the expression of BR-responsive genes as well as MADS-box genes that are required for lemma/palea specification, suggesting that OsPUB43 has a potential valuable application in the enlargement of grain size in rice.
• The OsPUB43 mutants display high sensitivity to exogenous BR, while OsPUB43-OE lines are hyposensitive to BR.
• The OsPUB43 protein is localized in the cytoplasm and nucleus.
