Gene Details:

• Gene ID: Zm00001eb369190
• Gene Symbol: ZmMYB74 ZmMYB33-1
• Gene Name: MYB-transcription factor 74
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• zma-miR159 targets ZmMYB74 and ZmMYB138 transcription factors to regulate grain size and weight in maize.
• Lines in which ZmMYB74 was knocked out using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) presented a similar enlarged grain phenotype as those with zma-miR159 overexpression.
• zma-miR159–ZmMYB modules act as an endosperm development hub, participating in the division and proliferation of endosperm cells.
• ZmTGA9-1/-2/-3 triple-gene mutants and ZmMYB33-1/-2 double-gene mutants displayed complete male sterility, but their double- or single-gene mutants showed male fertility.
• ZmMYB33-1 and ZmMYB33-2 act redundantly, and the two MYB33 paralogs as a whole are critical for maize male sterility.
