Natural variation in the atypical resistance gene Ptr confers broad‐spectrum neck blast resistance in rice

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Neck blast (NB), caused by Magnaporthe oryzae, infects rice (Oryza sativa L.) and reduces yield. Knowledge of NB resistance remains limited due to the lack of reliable resistance evaluation methods. Here, we applied a newly established neck injection method and performed a genome‐wide association study (GWAS) on 335 diverse accessions from the

Photosensitization by Brachiaria ruziziensis in a sheep herd

open access: yesToxicon, 2020
Some species of the genus Brachiaria are cultivated worldwide in tropical and subtropical climate regions as the main feed for ruminants. Several studies report photosensitization by Brachiaria decumbens, Brachiaria brizantha, and Brachiaria humidicola, but the poisoning by Brachiaria ruziziensis have been reported only twice.

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

open access: yesJournal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Associative diazotrophic bacteria and forage legumes sustain brachiariagrass pasture performance through enhanced root traits

open access: yesCrop Science, Volume 66, Issue 4, July/August 2026.
Abstract Interest in microbial plant growth‐promoting processes, particularly biological nitrogen (N) fixation (BNF), has increased globally as a strategic alternative to mineral N fertilization. Understanding the response of root traits to diverse N sources plays a critical role in unraveling canopy dynamics and improving decision‐making in forage ...

Impacts of large herbivores on savanna plant communities: Predictive models of herbivore selectivity and plant response

open access: yesEcology, Volume 107, Issue 7, July 2026.
Abstract Large herbivores are among the most ecologically influential and extinction‐prone animals. Megaherbivores, in particular, radically alter vegetation. Yet, few studies have tried to predict the impacts of herbivores—or their extinction—on plant species composition and community structure.
