Gene Details:

• Gene ID: Zm00001eb265710
• Gene Symbol: Wox3 Wox3a
• Gene Name: Wuschel-like homeobox3
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The planar, mediolateral outgrowth of both eudicot and monocot leaves is dependent on conserved Wuschel-like homeobox3 (Wox3) transcription-factor-encoding genes2,3,4. As described previously, Wox3 genes are expressed in the marginal domain of the SAM peripheral zone and at the intersection of the adaxial–abaxial (top–bottom) domains (that is, the rim1) of developing leaf primordial edges, where they promote mediolateral outgrowth of the marginal leaf domain.
• We show that rim function is regulated by genetically redundant Wuschel-like homeobox3 (Wox3) transcription factors. Higher-order mutations in maize Wox3 genes greatly reduce leaf width and disrupt ligule outgrowth and patterning.
• We refer to this edge-most region of Wox3 expression as the leaf primordial rim domain.
• Wox3 mutants perturb the marginal and lateral leaf domains.
• Higher-order Wox3 function and ligule development.
