Gene Details:

• Gene ID: Zm00001eb148390
• Gene Symbol: ZmWOX2A Wox2a
• Gene Name: Wuschel-like homeobox protein 2a
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A key to totipotency: Wuschel-like homeobox 2a unlocks embryogenic culture response in maize.
• The gene Wox2a was found to induce somatic embryogenesis and embryogenic callus proliferation.
• Transgenic B73 cells with strong constitutive expression of the B73 and A188 coding sequences of Wox2a were found to produce somatic embryos at similar frequencies, demonstrating that sufficient expression of either allele could rescue the embryogenic culture phenotype.
• In maize, Wox2a transcripts were detected in the zygote and in the apical domain of the early embryo.
• Wox2a expression was 1.3-fold higher in 2 mm Hi-II AxB immature zygotic embryos compared to B73 embryos of the same developmental stage.
