Gene Details:

• Gene ID: Zm00001eb247820
• Gene Symbol: ZmDEF1
• Gene Name: defensin 1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Overexpression of the ZmDEF1 gene increases the resistance to weevil larvae in transgenic maize seeds.
• The Zea mays defensin 1 (ZmDEF1) gene encodes the defensin 1 protein, which can inhibit alpha-amylase in the insect gut.
• ZmDEF1 was cloned into a pBetaPhaso-dest vector, which harbours phaseolin, a seed-specific promoter, and the Agrobacterium tumefaciens strain C58 harbouring the pBetaPhaso-ZmDEF1 vector was used to transfer the ZmDEF1 gene into two maize cultivars using immature embryos.
• The recombinant ZmDEF1 protein inhibited the alpha-amylase activity of the maize weevil larvae, and its ability to inhibit alpha-amylase is 54.52–63.09% greater than the ZmDEF1 protein extracted from non-transgenic plants.
