The dominant mutant Wavy auricle in blade1 disrupts patterning in a lateral domain of the maize leaf.

Mature maize leaves have defined cell types along the proximal distal and medial lateral axes. The patterning events that establish these axes take place early in leaf initiation. We have identified a new dominant mutation, Wavy auricle in blade1 (Wab1), which affects patterning in both axes in a do...
