Aerial plant organs are protected by the cuticle, a supramolecular biopolyester-wax assembly. We present protocols to monitor selective removal of epi- and intracuticular waxes from tomato fruit cuticles on molecular and micro scales by solid-state NMR and atomic force microscopy, respectively, and to assess the cross-linking capacity of engineered cuticular biopolyesters.

The plant cuticle is a waxy outer covering on plants that has a primary role in water conservation but is also an important barrier against the entry of pathogenic microorganisms. In this video, we demonstrate the analysis of plant cuticle mutants identified by forward and reverse genetics approaches.

Lipid polyesters constitute the structural components of two cell wall modifications, the plant cuticle and suberin-containing diffusion barriers. In this video, we describe a method to depolymerize cutin from whole delipidated leaves. The method can be applied to investigating mutants compromised in either cutin or suberin biosynthesis.
FAQs
Microscopy can distinguish the cuticle from surrounding structures when their optical properties differ. Contrast-enhancement methods strengthen these boundaries, while stains or fluorescent labels can bind to particular cuticular components and make them more visible. The resulting images reveal features such as layer boundaries, surface patterns, and associated structures that may be difficult to recognize without additional contrast.
Researchers can compare cuticular boundaries, surface patterns, and associated structures across specimens. In plants, these observations may support studies of development and barriers to water loss. In invertebrates, especially insects, imaging can help characterize external morphology. Comparing the same visual features between specimens connects structural variation with differences in biological condition or environmental interaction.
Stains and fluorescent labels increase contrast by binding to particular components of the cuticle. This selective signal can help separate relevant structures from surrounding material and clarify how cuticular components are distributed. Such information complements ordinary microscopic observation, allowing researchers to relate visible organization to properties such as protection, surface structure, or resistance to environmental conditions.
Images provide structural evidence that can be compared among developmental stages or environmental conditions. Changes in boundaries, surface patterns, or associated structures may indicate differences in cuticle organization. In plant biology, these observations are relevant to barriers against water loss and responses to environmental stress, while in invertebrates they can reveal changes in external morphology.
A basic workflow begins by selecting microscopy that can distinguish the relevant cuticular structures, then adding contrast enhancement when natural optical differences are insufficient. If component-specific information is needed, a stain or fluorescent label can be applied before imaging. The resulting views are examined for boundaries, surface patterns, distribution, and associated structures, then compared across specimens or conditions.
Researchers choose this approach when they need to connect an external layer with biological function. It can support comparisons of plant development, evaluation of barriers to water loss, assessment of environmental stress, and characterization of insect morphology. The method is especially useful when surface organization or component distribution provides evidence about protection, growth, or interactions with the environment.
