Gene Details:

• Gene ID: Zm00001eb428940
• Gene Symbol: NKD2
• Gene Name: NAKED ENDOSPERM2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Two O2-activated genes, bZIP17 and NAKED ENDOSPERM2 (NKD2), encode transcription factors, which can in turn coactivate other O2 network genes with O2.
• bZIP17 can form a heterodimer with O2 to jointly regulate the downstream regulatory genes of O2. Another target gene, NKD2, acts as a coactivator and is involved in regulating gene expression of O2-mediated endosperm cell differentiation.
• NKD2 (with its paralog NKD1) was previously shown to be involved in regulation of aleurone development
• These results indicate that NKD2 can act both as a coactivator and as a downstream effector of O2 in regulation of both its direct and indirect target genes.
• Double mutants have multiple (2-5) layers of peripheral endosperm cells that lack starch granules or other features of starchy endosperm.
