Gene Details:

• Gene ID: Zm00001eb304390
• Gene Symbol: ZmSUGCAR1|ZmNPF7.9|MN2
• Gene Name: Sucrose and Glucose Carrier1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The sugar transporter ZmSUGCAR1|ZmNPF7.9|MN2 of the nitrate transporter 1/peptide transporter family is critical for maize grain filling.
• ZmSUGCAR1|ZmNPF7.9|MN2 is specifically expressed in the basal endosperm transfer layer and loss-of-function mutation of ZmSUGCAR1|ZmNPF7.9|MN2 caused significantly decreased sucrose and glucose contents and subsequent shrinkage of maize kernels.
• The ZmSUGCAR1|ZmNPF7.9|MN2 orthologs SbSUGCAR1 (from Sorghum bicolor) and TaSUGCAR1 (from Triticum aestivum) displayed similar sugar transport activities in oocytes,
• The discovery of ZmSUGCAR1|ZmNPF7.9|MN2 uncovers a type of sugar transporter essential for grain development and opens potential avenues for genetic improvement of seed-filling and yield in maize and other grain crops.
