Abstract In corn seedlings (Zea mays L.) homozygous for the mutation gl5, the surface waxes are characteristically altered. In this mutant the main wax constituents (83.5%) are aldehydes while in the normal waxes alcohols predominate (62.7%). Moreover, in the normal waxes aldehydes and alcohols are made up mainly of the C32 term (99%), whereas in gl5 waxes the principal aldehyde is still C32 (90.7%) but the free alcohol composition pattern is noticeably modified. Here the predominant terms are C24, C26, and C28, with C32 representing only 16.6% of the total. The results indicate that the mutant induces a block in the synthesis of fatty alcohols while accumulating fatty aldehydes, the substrates from which the alcohols originate.
