Gene Details:

• Gene ID: Zm00001eb316720
• Gene Symbol: ZmTGA10|Zmbzip7
• Gene Name: bZIP-transcription factor 7
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• 12 genes in eight types, including ZmbHLH51, ZmbHLH122, ZmTGA9-1/-2/-3, ZmTGA10|Zmbzip7, ZmMYB84, ZmMYB33-1/-2, ZmPHD11 and ZmLBD10/27, were identified as maize new GMS genes by using DNA sequencing, phenotypic and cytological analyses.
• The knock-out mutants of ZmTGA10|Zmbzip7 showed nearly normal pollen development, but the mutant anthers failed to dehisce.
• These findings proved that ZmTGA10|Zmbzip7 functions in maize male fertility mainly by controlling anther dehiscence.
• Besides the five maize GMS TFs in the core regulatory pathway, three-type GMS TF genes identified here (ZmTGA10|Zmbzip7, ZmPHD11 and ZmMYB33-1/2) are the maize orthologs of AtTGA10/OsTGA10, AtMMD1/OsTIP3 and AtMYB33/65/OsGAMYB in Arabidopsis and rice, respectively, and may play the similar and conserved roles in controlling male sterility in plants.
