Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Glycoside Hydrolases Degrade Polymicrobial Bacterial Biofilms in Wounds [PDF]

open access: yes, 2016
The persistent nature of chronic wounds leaves them highly susceptible to invasion by a variety of pathogens that have the ability to construct an extracellular polymeric substance (EPS).

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Hydration of vinyl ether groups by unsaturated glycoside hydrolases and their role in bacterial pathogenesis

open access: yes, 2008
Many pathogenic microorganisms invade mammalian and/or plant cells by producing polysaccharide-degrading enzymes (lyases and hydrolases). Mammalian glycosaminoglycans and plant pectins that form part of the cell surface matrix are typical targets for ...

Imaging Staphylococcus aureus biofilms in vivo reveals neutrophil exclusion by PNAG exopolysaccharide

open access: yesmBio
Staphylococcus aureus forms biofilms on biotic and abiotic surfaces, enabling persistent infections that evade immune clearance. Although many S. aureus strains can produce the biofilm-associated exopolysaccharide, poly-β-1,6-N-acetyl-D-glucosamine (PNAG)

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Gut Microbiota Differences in Wild Asian Elephants From Pu'er, China

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study compared the gut microbiota of two wild Asian elephant populations in Jiangcheng (JC) and Liushun (LS), Yunnan, China. Significant differences in microbial structure, diversity, and function were found. Across samples, 24 phyla, 48 classes, 98 orders, 164 families, 288 genera, and 351 species were annotated.

Lignocellulose-derived natural humic substances modulate carbon metabolism and antibiotic resistance

open access: yesAgricultural Ecology and Environment
Lignocellulose-derived humic substances play a pivotal role in modulating soil environments, such as constituting a significant carbon reservoir and influencing microbial adaptations. However, the impact of lignocellulose-derived humic substances remains

Evolution of the α‐Glucosidase Gene Family in Apoidea

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study traces the origin of the α‐glucosidase gene family in bees back to approximately 140 million years ago, revealing that its evolutionary history closely aligns with the rise of angiosperms and coevolution. Furthermore, by identifying the core members Hbg1–3 and 28 key functional sites driven by positive selection, the study systematically ...
