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.

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.

Lens development involves interactions with other tissues. Several zebrafish eye mutants are characterized by an abnormally small lens size. Here we demonstrate a lens transplantation experiment to determine whether this phenotype is due to intrinsic causes or defective interactions with tissues that surround the lens.
FAQs
Different cuticle components point to different mechanisms of surface failure. In plants, altered cutin or wax biosynthesis can affect water retention and defense, whereas animal mutants can implicate structural proteins or extracellular matrix components in surface integrity, growth, or molting. Comparing these outcomes helps connect a candidate gene to the material properties and biological functions that the cuticle supports.
The comparison between plant and animal mutants preserves the genetic logic but changes the biological readout. Plant studies emphasize cutin and wax contributions to water retention and defense. Animal studies can emphasize structural proteins and extracellular matrix components associated with surface integrity, growth, or molting. This distinction helps investigators interpret a phenotype within the organism’s barrier biology.
Permeability and surface-integrity measurements convert a visible mutant phenotype into functional evidence. A defect in the external layer may be apparent microscopically, but these measurements indicate whether the barrier still supports water retention or remains intact. When combined with genetic and molecular results, they help distinguish a change in appearance from a change in cuticle performance.
In animals, altered growth or molting can extend cuticle analysis beyond surface appearance. These outcomes indicate that the external layer may be connected to developmental progression as well as structural integrity. Examining such phenotypes alongside microscopy and molecular assays helps relate a mutant gene to broader roles in maintaining the surface during growth or molting.
Researchers begin with organisms carrying a relevant genetic change, compare them with normal counterparts, and document phenotypic differences. Genetic crosses can help associate the phenotype with inheritance, while microscopy, molecular assays, and surface measurements provide complementary evidence. Interpreting these datasets together supports a connection between the altered gene, cuticle traits, and biological function.
Microscopy documents structural or visible differences between mutant and normal organisms. Molecular assays add evidence about gene-related changes, while measurements of surface integrity or permeability assess functional consequences. Because each method addresses a different level of analysis, combining them can connect an observed phenotype with both its molecular basis and its effect on the protective surface.
Cuticle mutant analysis supports research on development, stress responses, barrier biology, and gene function. In plant systems, findings can clarify how cutin and wax biosynthesis contributes to water retention and defense. In animal systems, the same approach can examine structural proteins or extracellular matrix components in relation to surface integrity, growth, and molting.
An abnormal phenotype should be interpreted by comparing normal and mutant organisms across structural, molecular, and functional observations. Concordance among microscopy, molecular assays, and integrity or permeability measurements strengthens the link between a genetic change and cuticle biology. The resulting evidence can inform studies of development, stress responses, barrier function, or gene function.
