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
Fixation preserves the specimen’s cuticular structures, while clearing removes internal tissues that could obscure the external pattern. Together, these steps make surface features more accessible for microscopy and help maintain a record that can be compared across specimens. Their value in genetics lies in revealing structural differences consistently enough to distinguish inherited phenotypes from normal developmental variation.
Cuticle patterns provide visible evidence of how genetic changes influence development. Differences in shape, arrangement, or overall morphology can be compared between mutant and control organisms to classify phenotypes. Because the preparation records externally patterned structures rather than only internal processes, it helps connect gene activity with observable developmental outcomes without treating morphology as a direct measurement of gene function.
Reliability depends on examining preparations under comparable conditions and evaluating the same kinds of surface features across specimens. Consistent fixation, clearing, mounting, and microscopy support reproducible comparisons, while control organisms provide a reference for normal morphology. This framework allows researchers to identify recurring changes in pattern, shape, or development that may characterize a genetic phenotype.
A typical workflow begins by fixing the specimen to preserve its structures, followed by clearing to remove internal tissues. The remaining cuticle is then mounted for microscopic examination. Researchers can document the resulting morphology and compare it with control or mutant preparations. The sequence is designed to expose external patterns clearly while retaining the structural information needed for genetic analysis.
This technique is particularly useful during genetic screens, where many specimens must be examined for visible differences. It also supports phenotype classification by providing a consistent basis for grouping organisms according to cuticular pattern, shape, or developmental appearance. Comparisons between mutant and control specimens can then help researchers investigate how gene activity contributes to externally visible traits.
Microscopic examination can reveal the organization and overall morphology of the preserved external structure. Researchers may record differences in pattern, shape, or developmental appearance and use those observations to classify phenotypes. In a genetics context, these findings provide a visible developmental readout that supports comparisons among organisms and helps evaluate whether a recurring structural change is associated with inherited variation.
