FIGURE 7.

Bulliform‐like cells in bulliform enriched mutants do not necessarily have cuticle nanoridges. Epidermal glue impressions of wild‐type (a–c) and three bulliform‐enriched mutants wty2 (d‐f), dek1‐D (g‐i), and Xcl1 (j‐l) at different magnifications. White arrowheads in (a and d) point to wild‐type‐like bulliform strips, while black arrowheads in (d, g, and j) mark abnormal bulliform strips. White arrow depicts nanoridges spanning cell‐to‐cell boundaries, black arrow indicates a pavement cell without cuticle nanoridges. In the middle and right columns, higher magnification views of bulliform‐like cells in each genotype show their surface features in more detail. Note the absence of nanoridges on bulliform‐like cells in Xcl1 mutants. Scale bar in (a,d,g,j) = 100 µm, in all others 50 µm
