A co-opted steroid synthesis gene, maintained in sorghum but not maize, is associated with a divergence in leaf wax chemistry. [PDF]

Proc Natl Acad Sci U S A, 2021
Virtually all land plants are coated in a cuticle, a waxy polyester that prevents nonstomatal water loss and is important for heat and drought tolerance. Here, we describe a likely genetic basis for a divergence in cuticular wax chemistry between Sorghum

Grain and Domain Microstructure in Long Chain N-Alkane and N-Alkanol Wax Crystals. [PDF]

Cryst Growth Des
Waxes comprise a diverse set of materials from lubricants and coatings to biological materials such as the intracuticular wax layers on plant leaves that restrict water loss to inhibit dehydration.

Phenotypic Cuticle Plasticity at High Elevation: Is Microstructure and Microchemistry Related to Water Permeability? [PDF]

Plant Cell Environ
ABSTRACT Kalmia procumbens (K. procumbens), a ubiquitous alpine dwarf shrub, thrives at high elevations, particularly on wind‐exposed sites. Plants on contrasting north‐ and southeast‐facing slopes at ~2237 m elevation exhibit differences in leaf colour and growth, suggesting acclimative strategies.

Cuticle Structure in Relation to Chemical Composition: Re-assessing the Prevailing Model [PDF]

, 2016
The surface of most aerial plant organs is covered with a cuticle that provides protection against multiple stress factors including dehydration. Interest on the nature of this external layer dates back to the beginning of the 19th century and since then,

Exploring Plant Surface Chemical Variability: Lettuce Leaf as Model. [PDF]

Physiol Plant
ABSTRACT The plant cuticle has been traditionally believed to be a continuous lipophilic layer covering most aerial plant surfaces, but recent methodological advances based on Atomic Force Microscopy (AFM) enabled mapping the distribution of hydrophilic and hydrophobic areas in the papillae and pavement cells of rose petals and olive leaf trichomes ...

Effects of Different Postharvest Treatments on Cuticle Microstructure and Components of 'Nanfeng' Mandarins (Citrus reticulata Blanco cv. Kinokuni) During Cold Storage

Shipin gongye ke-ji, 2022
The cuticle plays an important role in postharvest physiology of fruit, and its microstructure and components could be affected by different postharvest storage conditions.

First line of defence: Eucalyptus leaf waxes influence infection by an aggressive fungal leaf pathogen. [PDF]

Plant Biol (Stuttg)
Leaf wax compounds of Eucalyptus modulate the germination and infection of the leaf blight pathogen Teratosphaeria destructans. Abstract Leaf epicuticular waxes provide important anatomical and chemical defences against fungi that infect leaves. In this study we analysed the leaf wax composition of Eucalyptus grandis × Eucalyptus urophylla hybrids with

Project ChemicalBlooms: Collaborating with citizen scientists to survey the chemical diversity and phylogenetic distribution of plant epicuticular wax blooms. [PDF]

Plant Direct
Abstract Plants use chemistry to overcome diverse challenges. A particularly striking chemical trait that some plants possess is the ability to synthesize massive amounts of epicuticular wax that accumulates on the plant's surfaces as a white coating visible to the naked eye.

Composition differences between epicuticular and intracuticular wax substructures: How do plants seal their epidermal surfaces? [PDF]

Journal of Experimental Botany, 2010
The protective wax coating on plant surfaces has long been considered to be non-uniform in composition at a subcellular scale. In recent years, direct evidence has started to accumulate showing quantitative compositional differences between the epicuticular wax (i.e. wax exterior to cutin that can be mechanically peeled off) and intracuticular wax (i.e.

A Proposed Method for Simultaneous Measurement of Cuticular Transpiration From Different Leaf Surfaces in Camellia sinensis

Frontiers in Plant Science, 2020
The plant cuticle is the major barrier that limits unrestricted water loss and hence plays a critical role in plant drought tolerance. Due to the presence of stomata on the leaf abaxial surface, it is technically challenging to measure abaxial cuticular ...
