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
Controlled disruption balances removal of the obstructing external layer with preservation of accessible internal structures. Excessive mechanical or chemical treatment could compromise the tissues being examined, while insufficient treatment may leave immune cells, microbes, or tissue damage hidden. This balance improves the reliability of microscopy, staining, and molecular assays used to assess host-pathogen interactions.
Mechanical and chemical disruption provide different routes for separating the cuticular layer from underlying tissues. Mechanical treatment physically removes the surface, whereas chemical treatment alters the cuticle to enable separation. The appropriate choice depends on whether the preparation must preserve accessible internal structures for visualization, staining, or molecular analysis.
Removing the surface barrier can reveal patterns that are difficult to observe in an intact host, including immune-cell distribution, microbial localization, tissue damage, and responses associated with barrier integrity. These observations connect the condition of the external cuticle with events occurring internally, helping investigators examine how host defenses relate to infection phenotypes.
Preparation centers on controlled mechanical or chemical disruption of the cuticular layer, followed by separation that leaves underlying tissues accessible for analysis. The exposed material can then be examined by microscopy, processed with stains, or evaluated using molecular assays. Maintaining tissue accessibility throughout the workflow is essential for interpreting immune and infection-related features.
The technique is useful when an intact external surface obscures host defense or pathogen-associated features. Investigators can apply it to examine immune cells, microbial localization, tissue damage, and barrier responses in invertebrate hosts. It therefore supports studies of innate immunity and helps relate surface integrity to internal consequences of infection.
Peeled samples allow researchers to compare external barrier integrity with internal infection phenotypes. Evidence of altered barrier responses, localized microbes, immune-cell involvement, or tissue damage can help clarify how pathogens interact with host tissues. These relationships provide context for evaluating host susceptibility and investigating invasion without relying solely on observations of the intact surface.
