Burning reduced Actinobacteriota and Firmicutes but increased Proteobacteria. Rhizosphere networks were denser, but burning reduced their overall connectivity. Burnt straw increased specialist and generalist taxa, especially in the rhizosphere. Straw management significantly influences soil microbial dynamics, shaping biodiversity and resistance in agroecosystems. This study investigated how distinct straw management practices...

Quillaja lancifolia D. Don (current correct taxonomic designation of the synonym Q. brasiliensis (A. St.-Hil. & Tul.) Mart.) is a promising source of triterpenoid saponins of high biotechnological value, including QS-21, a potent immunological adjuvant used in human vaccine formulations, producible in cell suspension cultures. Herein, an efficient Agrobacterium tumefaciens –mediated genetic transformation protocol for generati...

Optimizing maize–Brachiaria intercropping requires effective weed management with selective maize herbicides. This study evaluated the spray performance and efficacy of atrazine + nicosulfuron for weed management in maize–Brachiaria intercropping, focusing on how droplet classes and spray volumes affect maize growth and yield. The deposition experiment was conducted in a greenhouse in a completely randomized design with six re...

Estimating low flows is essential for water-resources management, especially in semi-arid regions with sparse hydrometric monitoring and high drought vulnerability. This study advances low-flow regionalization in a Brazilian semi-arid basin by integrating spatial climate data, precipitation and actual evapotranspiration from TerraClimate, into regional regression models. Of fourteen compiled gauges, ten met data-quality criter...

Bacterial resistance constitutes one of the main threats to global public health, driving the search for therapeutic strategies capable of restoring the effectiveness of antimicrobials. Among the mechanisms involved, efflux pumps stand out, reducing the intracellular concentration of drugs and contributing to multidrug resistance. In this context, inhibitors of these pumps emerge as a promising approach, as they increase the i...

Staphylococcus aureus is a Gram-positive coccus-type bacterium responsible for colonizing various sites of the host’s body, thus generating several pathologies such as pneumonia, osteomyelitis, endocarditis, and even cases of sepsis. Eugenol, dihydroeugenol, guaiacol, and phenol are phenolic compounds with antimicrobial activities, as is the drug metronidazole; therefore, eight substances were synthesized by coupling metronida...
