Gene Details:

• Gene ID: Zm00001eb193950
• Gene Symbol: Dek15 scc4
• Gene Name: defective kernel 15
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The cells in the Dek15 endosperm and embryo exhibited precocious sister chromatid separation and other chromosome segregation errors, including misaligned chromosomes, lagging chromosomes, and micronuclei, resulting in a high percentage of aneuploid cells.
• Maize Dek15 Encodes the Cohesin-Loading Complex Subunit SCC4 and Is Essential for Chromosome Segregation and Kernel.
• The Dek15 mutation was found to disrupt the mitotic cell cycle and endoreduplication, resulting in a reduced endosperm and embryo lethality.
• Dek15/SCC4 in mitotic chromosome segregation and kernel development in maize.
• Dek15/Scc4 is required to precisely regulate chromosome segregation, possibly by interacting with the chromatin remodeling complex to assist cohesin binding to chromatin.
• Dek15 collapsed floury endosperm; lethal; cultured embryos green.
