Gene Details:

• Gene ID: Zm00001eb344620
• Gene Symbol: EMP80
• Gene Name: empty pericarp80
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• EMP80 mediates the C-to-U editing of nad7 and atp4 and interacts with ZmDYW2 in maize mitochondria.
• Loss of EMP80 function arrests embryogenesis and endosperm development in maize.
• EMP80 is a PPR-E+ protein localised to mitochondria. An absence of EMP80 abolishes the C-to-U RNA editing at nad7-769 and atp4-118 sites, resulting in a cysteine-to-arginine (Cys→Arg) change in Nad7 and Atp4 in the EMP80 mutant.
• Co-expression of ZmNUWA enhances the interaction between EMP80 and ZmDYW2, suggesting that EMP80 potentially recruits ZmDYW2 as a trans deaminase through protein–protein interaction, and ZmNUWA may function as an enhancer of this interaction.
