The proprotein convertase BLI-4 promotes collagen secretion prior to assembly of the Caenorhabditis elegans cuticle.

open access: yesPLoS Genetics, 2023
Some types of collagens, including transmembrane MACIT collagens and C. elegans cuticle collagens, are N-terminally cleaved at a dibasic site that resembles the consensus for furin or other proprotein convertases of the subtilisin/kexin (PCSK) family ...

Direct Evidence for a Radial Gradient in Age of the Apple Fruit Cuticle

open access: yesFrontiers in Plant Science, 2021
The pattern of cuticle deposition plays an important role in managing strain buildup in fruit cuticles. Cuticular strain is the primary trigger for numerous fruit-surface disorders in many fruit crop species.

Live Detection of Intracellular Chitin in Butterfly Wing Epithelial Cells In Vivo Using Fluorescent Brightener 28: Implications for the Development of Scales and Color Patterns

open access: yesInsects, 2023
Chitin is the major component of the extracellular cuticle and plays multiple roles in insects. In butterflies, chitin builds wing scales for structural colors.

Genetic variation and potential for genetic improvement of cuticle deposition on chicken eggs

open access: yesGenetics Selection Evolution, 2019
Background The cuticle is an invisible glycosylated protein layer that covers the outside of the eggshell and forms a barrier to the transmission of microorganisms.

The Morphological and Anatomical Traits of the Leaf in Representative Vinca Species Observed on Indoor- and Outdoor-Grown Plants

open access: yesPlants, 2021
Morphological and anatomical traits of the Vinca leaf were examined using microscopy techniques. Outdoor Vinca minor and V. herbacea plants and greenhouse cultivated V. major and V. major var. variegata plants had interspecific variations.

The structure of insect cuticles [PDF]

open access: yesProceedings of the Royal Society of London. Series B - Biological Sciences, 1947
Abstract The amount of chitin and of protein in the blowfly larval cuticle remains essentially unchanged during the process of hardening and darkening of the puparium. In the formation of the puparium there is a gain of weight of about 6 % over the larval cuticle weight, and this can be accounted for by the incorporation of phenolic ...

Chemical and structural analysis of Eucalyptus globulus and E. camaldulensis leaf cuticles: a lipidized cell wall region

open access: yesFrontiers in Plant Science, 2014
The plant cuticle has traditionally been conceived as an independent hydrophobic layer that covers the external epidermal cell wall. Due to its complexity, the existing relationship between cuticle chemical composition and ultra-structure remains unclear

Egg envelopes and cuticle renewal in Porcellio embryos and marsupial mancas

open access: yesZooKeys, 2012
An important adaptation to land habitats in terrestrial isopod crustaceans is development of embryos in a fluid-filled female brood pouch, marsupium. The study brings insight into the structure and protective role of egg envelopes and cuticle renewal ...

The effect of management practices on eggshell cleanliness, bacteria levels, and cuticle deposition in pastured poultry

open access: yesJournal of Applied Poultry Research, 2023
SUMMARY: Small-scale egg production is a growing industry in New England. However, foodborne illness risk exists from small-scale pastured eggs due to lack of guidelines for safe handling and management practices.

The Cuticle of Mammalian Hair [PDF]

open access: yesNature, 1950
STUDIES in these laboratories have suggested that the arrangement of scales in the cuticles of mammalian hairs can be more accurately revealed by the examination of fibre sections, using ultra-violet light, than by the use of the electron microscope. This work has shown that the thickness of the cuticle of mammalian hair depends upon the arrangement of
