A hydrophobic cuticle that serves as a protective barrier against non-stomatal water loss and environmental damage covers the surfaces of terrestrial plants. Cuticular waxes are complex mixtures of hydrophobic lipids, consisting mostly of very-long-chain fatty acids and their derivatives. KCS is the key enzyme in the enlongation of VLCFA and VLCFA is the precursors of cuticular wax.In the present study, we dectected the composition and and observed the ultrastructure of cuticular wax on the leaves of Tritic...
