Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

open access: yesIntegrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Preparation of chitin nanofibers by surface esterification of chitin with maleic anhydride and mechanical treatment [PDF]

open access: yes
Esterification with maleic anhydride significantly improved the mechanical disintegration of chitin into uniform 10-nm nanofibers. Nanofibers with 0.25° of esterification were homogeneously dispersed in basic water due to the carboxylate salt on the ...

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Integrative transcriptomic and machine learning approaches reveal candidate genes for silk and venom production in Bibionomorpha (Diptera)

open access: yesInsect Molecular Biology, EarlyView.
Multi‐species transcriptomics and deep learning identified candidate genes associated with silk and venom production in Bibionomorpha. Venom‐associated genes were enriched in proteases, inhibitors and pore‐forming proteins, whereas silk‐related genes showed chitin‐binding and peritrophin domains. Integrating co‐expression networks, machine learning and

A polyphasic approach to the study of chitinolytic bacteria in soil [PDF]

open access: yes
Chitin is the most abundant nitrogen-containing polymer in nature, with >1x10^10 tonnes produced annually in terrestrial and marine habitats. Chitinolytic bacteria are able to degrade this recalcitrant substrate through a multiplicity of chitinases.

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

open access: yesJournal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

The digestion of chitin by callitrichids

open access: yes
Studies of wild callitrichids reveal limited data about their complex diets. As insectivorous primates it is likely that they can digest chitin. Using the common marmoset, Callithrix jacchus, as a model, this study assessed chitin digestibility and ...

A System Analysis and Design For Selecting Chitin and Chitosan Industry Location By Using Comparative Performance Index Method [PDF]

open access: yes, 2015
The chitin and chitosan industry development is motivated by its wide application of chitin and chitosan as biopolymer and by its potential raw material from crustacean shell which is known as waste in shrimp processing industry, to help reducing the ...

When biology meets materials science – Interdisciplinary applications of electron microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.
