Gene Details:

• Gene ID: Zm00001eb226270
• Gene Symbol: ZmTti2 TTI2 dek38
• Gene Name: defective kernel38
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Further analysis showed that the mutation of the ZmTti2 gene led to the phenotype of grain defects.
• Maize defective kernel mutant generated by insertion of a Ds element in a gene encoding a highly conserved TTI2 cochaperone.
• The maize dek38 gene encodes a TTI2 (Tel2-interacting protein 2) molecular cochaperone.
• dek38-Dsg displays reduced pollen transmission, indicating TTI2’s importance in male reproductive cell development.
• ZmTti2’s roles in storage protein accumulation and BETL development should be investigated further.
• ZmTti2 mutants are embryonic lethal, has a defective basal endosperm transfer (BETL) layer, and results in a smaller seed with highly underdeveloped endosperm.
