Leaf surface microstructure and morphology of WT and glossy mutant. Comparative scanning electron micrographs of leaf surface at magnification of 6000x of (A) WT waxy, (B) mutant glossy. Large quantities of spiky, needle-like crystals microscopic wax crystals were uniformly covered on the leaf surface of waxy WT onion, whereas in glossy type, relatively few wax crystals were scattered around the stomatal region alone. (C) Greenish gray (glaucous) phenotype of WT waxy, (D) Shiny glossy green phenotype of mutant glossy. (E) WT waxy onion leaf surface showing water droplets due to its hydrophobic nature, (F) water droplets were easily adhered and coalesced on to the leaf surface of mutant glossy.
