• 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

• OsBZR1~BZR1, OsPUB43, CRISPR-Cas9 Mediated Mutation in OsPUB43 Improves Grain Length and Weight in Rice by Promoting Cell Proliferation in Spikelet Hull., Furthermore, the transient transcriptional activity assay shows that OsBZR1 can activate the expression of OsPUB43
