Immunization with peptide encapsulated within synthetic spores activates T cell responses and reduces tumor growth

mBio
Peptide-based therapeutic immunizations represent safe approaches to elicit antigen-specific T cell responses, but their broad utility remains limited due to poor immunogenicity and short in vivo stability due to rapid degradation and clearance. Here, we

Comparative evaluation of nonlinear disease progress models for quantitative assessment of peanut leafspot disease

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Leafspot disease causes up to 70% yield losses in peanut production areas across the globe. One way to curb this menace is to use leafspot resistant peanut (Arachis hypogaea L.) varieties. In breeding for disease resistance, quantitative characterization of disease dynamics, including initial inoculum (y0) and apparent infection rate (r), is ...

Evolving a plant-beneficial bacterium in soil vs. nutrient-rich liquid culture has contrasting effects on in-soil fitness

Applied and Environmental Microbiology
Inoculation of plant-beneficial microbes into agricultural soils can improve crop growth, but such outcomes depend on microbial survival. Here, we assessed how exposure to prior environmental conditions impacts microbial in-soil fitness, particularly ...

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4579-4596, September 2026.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Sporulation at reduced water activity impairs germination kinetics of Bacillus subtilis spores

Applied and Environmental Microbiology
While the effect of sporulation temperature on spore germination has been extensively studied, the effect of other relevant environmental factors such as water activity (aw) has been overlooked, despite the fact that sporulation niches with lower ...

Conformational diversity in poly‐HAMP arrays and its implications for signal transduction

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Prokaryotic transmembrane receptors are built around a helical coiled‐coil backbone, with sensory, modulatory, and effector domains arranged along its length. The modulatory HAMP domain forms a parallel four‐helix coiled coil integrated into this backbone, typically connecting transmembrane segments with downstream cytosolic domains.

Segregation of sister chromosomes during the shape change of developing Myxococcus xanthus cells

Journal of Bacteriology
Chromosome organization is critical for the maintenance of genetic integrity. Most studies of bacterial nucleoids have focused on growing rod-shaped organisms. Studying nucleoid dynamics during Myxococcus xanthus development offers the unique opportunity

Resistance of Botrytis cinerea to anilinopyrimidine fungicides: A novel ARMS‐PCR method for the detection of Bcpos5 mutations and characterization of resistance using CRISPR/Cas9 editing

Pest Management Science, Volume 82, Issue 9, Page 8189-8198, September 2026.
A TETRA‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method was developed for simultaneous detection of the L412F/V and G408V mutations. L412F/V mutants were created using the CRISPR/Cas tool and no fitness cost was observed.

Morphological and molecular characterization of Alternaria spp. causing leafspot and flower blight of marigold (Tagetes spp.)

Journal of Horticultural Sciences
Globally, leaf spot and flower blight disease, caused by Alternaria spp., is the most devastating disease of marigold, especially during rainy season when moderate temperature and high relative humidity prevails.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
