Gene Details:

• Gene ID: Zm00001eb314610
• Gene Symbol: ZmACO2 ZmACOB acco2
• Gene Name: 1-aminocyclopropane-1-carboxylate oxidase2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Confirmation of qEL7 by gene editing of ZmACO2 leads to a reduction in ethylene production in developing ears, and promotes meristem and flower development, resulting in a ~13.4% increase in grain yield per ear in hybrids lines.
• ZmACO2 negatively controls ear length and grain yield.
• ZmACO2 regulates ethylene biosynthesis in developing ears.
• These results suggest that sequence variation in the promoter leads to the differences in ZmACO2 expression and ear phenotypes between qEL7Ye478 and qEL7SL17.
• ZmACO2 is the candidate gene of qEL7 and negatively affects yield-related traits.
