The Msn2 Transcription Factor Regulates Acaricidal Virulence in the Fungal Pathogen Beauveria bassiana

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Beauveria bassiana holds promise as a feasible biological control agent for tick control. The B. bassiana stress–response transcription factor Msn2 is known to contribute to fungal growth, conidiogenesis, stress–response and virulence towards insects ...

Mechanism of Cuticle Hole Development in Human Hair Due to UV-Radiation Exposure

open access: yesCosmetics, 2018
Hair is easily damaged by ultraviolet (UV) radiation, bleaching agents or permanent wave treatments, and as damage progresses, hair loses its gloss, develops split ends and breaks.

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 astacin metalloprotease moulting enzyme NAS-36 is required for normal cuticle ecdysis in free-living and parasitic nematodes [PDF]

open access: yes, 2010
Nematodes represent one of the most abundant and species-rich groups of animals on the planet, with parasitic species causing chronic, debilitating infections in both livestock and humans worldwide. The prevalence and success of the nematodes is a direct

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.

Biomineralisation in the Palaeozoic oceans: evidence for simultaneous crystallisation of high and low magnesium calcite by phacopine trilobites [PDF]

open access: yes, 2012
The chemical composition and microstructure of the calcite cuticles of eleven species of phacopine trilobites have been investigated by electron beam imaging, diffraction, and microanalysis, and results reveal that the lenses of their schizochroal eyes ...

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 ...

A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]

open access: yes, 2004
Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...
