Epicuticular wax and cuticle layer of air-dried adaxial leaf surfaces of wild type (WT), the <i>BraLTP1-20</i> and <i>BraLTP1-22</i> overexpressor using scanning electron microscopy.

<p>The experiments were repeated for 3 times with at least five plants for each time. (A) Wax crystals on the WT leaf were dense, with high proportion of tubular-like wax crystals. (B and C) Wax crystals are sparsely distributed on <i>BraLTP1-20 and BraLTP1-22 B. napus</i> leaves. Bar = 5 µm.
