Gene Details:

• MSU gene ID: LOC_Os07g47360
• RAPdb gene ID: Os07g0669800 ,Os07g0669900
• Gene Symbol: OsCW-ZF7 WG7
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Knockout of OsCW-ZF7 caused defective development of awns.
• Here, we identified three cysteine-tryptophan (CW)-domain containing zinc finger (ZF) proteins involved in histone recognition, namely OsCW-ZF3, OsCW-ZF5 and OsCW-ZF7.
• The grain size of WG7 knockout mutants and WG7 overexpression lines indicated that WG7 is a positive regulator of grain size.
• EMSAs and ChIP-qPCR assay confirmed that WG7 directly bound to the promoter of OsMADS1, a grain size gene, and thereby significantly activated its expression.
• These findings demonstrated that WG7 upregulated OsMADS1 expression by directly binding to its promoter, enhanced histone H3K4me3<U+00A0>enrichment in the promoter and ultimately increased grain width.
• WG7 underwent directional selection due to the poor fertility of the nonfunctional mutant.
• WG7 encodes a cysteine-tryptophan (CW) domain-containing transcriptional activator.
