Division of Plant Science and Technology, University of Missouri, Columbia, MO, 65211, USA.
The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, has evolved resistance to nearly every management tactic utilized in the field. This study investigated the resistance mechanisms in a WCR strain resistant to the Bacillus thuringiensis (Bt) protein eCry3.1Ab using dsRNA to knockdown WCR midgut genes previously documented to be associated with the resistance.

Hydrothermal biochar has demonstrated potential in enhancing crop growth by improving soil properties and microbial activity; however, its effectiveness varies with application rate, with excessive amounts potentially inhibiting plant growth. This study employed a pot experiment approach to compare varying application rates of hydrothermal biochar (ranging from 0 to 50 t/ha) and to analyze its effects on alfalfa biomass, photosynthetic efficiency, soil nutrient content, and microbial community composition. Biochar application increased alfalfa dry weight by 12.

The increasing concern over microbial resistance to conventional antimicrobial agents used in food preservation has led to growing interest in plant-derived antimicrobial peptides (AMPs) as alternative solutions. In this study, the antimicrobial mechanisms of chia seed-derived peptides YACLKVK, KLKKNL, KLLKKYL, and KKLLKI were investigated against Staphylococcus aureus (SA) and Escherichia coli (EC). Fluorometric assays and scanning electron microscopy (SEM) demonstrated that the peptides disrupt bacterial membranes, with propidium iodide (PI) uptake reaching 72.

Institute of Agriculture and Life Science, Gyeongsang National University, Jinju, 52828, Republic of Korea.
Heat stress (HS) is an impactful condition in ruminants that negatively affects their physiological and rumen microbial composition. However, a fundamental understanding of metabolomic and metataxonomic mechanisms in goats under HS conditions is lacking. Here, we analyzed the rumen metabolomics, metataxonomics, and serum metabolomics of goats (n = 10, body weight: 41.

Department of Pharmacy, University of Salerno, Via Giovanni Paolo II, 132, Fisciano, 84084, Salerno, Italy.
This research aims at the valorization of fennel by-products from the Campania region (Southern Italy). A phytochemical characterization of the hydroalcoholic extracts (HEs) and of the essential oils (EOs) from edible and non-edible parts (waste) of Foeniculum vulgare Mill. was carried out using HRESIMS and GC-MS.
