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.

Here we describe a basic protocol for fluorescent labeling of different elements of heart tubes from larva and adult Drosophila melanogaster. These specimens are well-suited for imaging via fluorescent or confocal microscopy. This technique permits detailed structural analysis of the features of the hearts from a powerful model organism.
FAQs
In arthropods, chitin contributes structural material to the exoskeleton, while structural proteins help maintain a combination of flexibility and durability. That combination allows the outer layer to protect body surfaces while resisting abrasion and physical damage. Examining how these materials are organized therefore connects microscopic composition with the mechanical protection provided by the cuticle.
Plant cutin and waxes create a water-resistant surface over epidermal cells. This barrier can reduce water loss while still participating in regulation of exchange with the environment. Studying their contribution is especially relevant when explaining how plant cuticles support adaptation to drought and influence interactions between plants and their habitats.
Cuticle structure is relevant to insect growth and molting because the arthropod outer layer forms part of the body system considered as insects change during their life cycle. Investigating its organization and composition helps connect exoskeletal properties with these biological processes, giving researchers a framework for interpreting how insects develop and interact with their surroundings.
Comparing arthropod and plant cuticles reveals that different structural materials can support related protective functions. Chitin and structural proteins are associated with a flexible, durable exoskeleton, whereas cutin and waxes form a water-resistant plant barrier. This comparison helps researchers relate material composition to water balance, abrasion resistance, pathogen defense, and environmental adaptation across biological systems.
Cuticle structure matters in ecology and agriculture because it links an organism's outer barrier to environmental pressures. In plants, examining water-resistant cuticles can help frame questions about drought adaptation; across organisms, barrier properties also relate to pathogen exposure and physical damage. These connections support research on habitat interactions and how organisms withstand challenging conditions.
Biomimetic material design can draw on the contrasting properties associated with biological cuticles. Arthropod layers suggest interest in combining flexibility, durability, and abrasion resistance, while plant layers highlight water resistance and reduced water loss. Studying cuticle structure therefore provides design principles for protective materials that seek to reproduce useful biological combinations rather than copy only one material.
