The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor

Chemical preparation and structural characterization of a homogeneous series of chitin/chitosan oligomers

open access: yes, 2008
International audienceThe preparation of a homogeneous series of chitin/chitosan oligomers (chito-oligomers) with the same distribution of degrees of polymerization (DP) ranging from 2 to 12, but with various average degrees of N-acetylation (DA) from 0 ...

Acetylation Activity and Specificity of Peptidoglycan Deacetylase BsPdaC Acting in Reverse on Chitooligosaccharides

open access: yesChemCatChem, Volume 18, Issue 10, 27 May 2026.
Bacillus subtilis PdaC is the first peptidoglycan deacetylase able to act in reverse, acetylating a glucosamine oligomer (chitopentaose) with a pattern of acetylation mirroring the natural deacetylation reaction with unique final regioselectivity, acetylating all but the reducing end of D5.

Gamma Irradiation Improves Defatted Hermetia illucens Larvae Meal as a Partial Fishmeal Substitute for Litopenaeus vannamei: Growth, Nutrient Utilization, Intestinal Microbiota, and Environmental‐Economic Sustainability

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
The current study was conducted to evaluate whether gamma (γ)‐irradiation improves the efficacy of defatted Hermetia illucens larvae (HIL) meal as the fishmeal protein substitute in Litopenaeus vannamei. The reference diet (diet R) contained 400 g/kg fishmeal, while two experimental diets replaced 50% of fishmeal with either nonirradiated (diet HIL) or

Native symbiotic rhizobia strains improve yield and nitrogen fixation in underutilized Bambara groundnut (Vigna subterranean L. Verdc.)

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Bambara groundnut (BG) (Vigna subterranean L. verdc) is a highly nutritious and economically important leguminous crop of African origin that forms symbiotic relationships with nitrogen‐fixing rhizobia, but it has a low yield. Currently, there is a paucity of information on effective rhizobium inoculant (to improve the yield) for BG, which are

A potential role of IL-6 in the chito-oligosaccharide-mediated inhibition of adipogenesis

open access: yes, 2011
Recent studies have suggested that chito-oligosaccharides can have anti-adipogenic properties. The objectives of the present study were to evaluate the anti-adipogenic potential of four different chito-oligosaccharides (molecular weight (MW) < 1000 ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Expression of endochitinase and exochitinase in lettuce chloroplasts increases plant biomass and kills fungal pathogen Candida albicans

open access: yesPlant Biotechnology Journal, Volume 23, Issue 5, Page 1437-1451, May 2025.
Expression of exochitinase and endochitinase in lettuce highlights the potential of chloroplast genetic engineering for sustainable agriculture and biomedical applications, offering a safer alternative to chemical fertilizers and fungicides. Summary Lettuce (Lactuca sativa) is a popular leafy vegetable with global production of ~28 million Mt ...
