Gene Details:

• Gene ID: Zm00001eb161560
• Gene Symbol: ZmSWEET7 sweet6a
• Gene Name: sugars will eventually be exported transporter6a
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Homologous overexpression of the ZmSWEET7 increases the maximum quantum yield of photosystem II photochemistry (FV/FM), CO2 assimilation rate (A), soluble sugar content, and dry matter, with the quantum yield for CO2 fixation efficiency (phiCO2) showing the most significant increase.
• There is a strong positive association between phiCO2 and soluble sugar content, dry matter, and FV/FM in ZmSWEET7 overexpressing mutants compared to the wild.
• These findings indicate that ZmSWEET7-mediated CO2 fixation efficiency rather than assimilation rate plays a positive pleiotropic role in C accumulation in the form of sugar or dry matter via increased FV/FM. This work lays a strong foundation for salt-tolerant forage maize genetic improvement.
