Gene Details:

• Gene ID: Zm00001eb167600
• Gene Symbol: ZmGa1P
• Gene Name: pollen/male determinant of the Ga1 locus
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Maize Gametophyte factor1 (Ga1) is an intraspecific UCI system and has been utilized in breeding.
• Homozygous transgenic plants expressing ZmGa1P in a ga1 background can fertilize Ga1-S plants and can be fertilized by pollen of ga1 plants.
• The cloning of ZmGa1P,a pollen-expressed PECTIN METHYLESTERASE (PME) gene at the Ga1 locus that can confer the male function in the maize UCI system.
• ZmGa1P protein is predominantly localized to the apex of growing pollen tubes and may interact with another pollen-specific PME protein.
• ZmGa1P encodes a pollen PME and modulates pollen tube growth.
