Gene Details:

• Gene ID: Zm00001eb150140
• Gene Symbol: ZmMYB138 ZmMYB33-2
• Gene Name: MYB-transcription factor 138
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The overexpression of ZmMYB138 had a significant effect on the activities of the promoters of Bt2 and Ae1.
• Combined with the transcriptional regulation of SSGs by ZmMYB138 and ZmMYB115, Zma-miR159k-3p can indirectly regulate starch biosynthesis in maize endosperm by regulating the expression of ZmMYBs.
• ZmMYB138 may be positively correlated to the starch and amylopectin contents in maize endosperm.
• zma-miR159 targets ZmMYB74 and ZmMYB138 transcription factors to regulate grain size and weight in maize.
• ZmMYB33-1 and ZmMYB33-2 act redundantly, and the two MYB33 paralogs as a whole are critical for maize male sterility.
• ZmTGA9-1/-2/-3 triple-gene mutants and ZmMYB33-1/ZmMYB33-2 double-gene mutants displayed complete male sterility, but their double- or single-gene mutants showed male fertility.
• zma-miR159–ZmMYB modules act as an endosperm development hub, participating in the division and proliferation of endosperm cells.
