Gene Details:

• Gene ID: Zm00001eb369340
• Gene Symbol: ZmCYCB1-1 cyc4
• Gene Name: cyclin4
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• In situ hybridization and toluidine blue staining indicated that ZmCYCB1-1 was highly expressed in the plumule of embryos, and the cells of the plumule were smaller, denser, and more regularly arranged in ZmCYCB1-1 overexpression plants.
• Knocking out ZmCYCB1-1 resulted in plants with slow growth.
• ZmCYCB1-1 overexpression significantly accelerated embryo growth and increased seed size.
• ZmCYCB1-1 was highly expressed in the plumule of embryos, and the cells of the plumule were smaller, denser, and more regularly arranged in ZmCYCB1-1 overexpression plants.
• Overexpression of ZmCYCB1-1 in maize also resulted in an increased ear length and enhanced kernel weight by increasing kernel width.
• ZmCYCB1-1 regulates embryo growth and seed size, making it an ideal target for efforts aimed at maize yield improvement.
