Passion fruit, a tropical species cultivated across various nations, faces challenges in expanding its cultivation areas due to several constraints, including total crop losses, caused by the fruit woodiness virus. In Brazil, this condition is attributed to the cowpea aphid-borne mosaic virus (CABMV), and currently, no passion fruit cultivars are resistant to this virus. This study integrates classical breeding and molecular a...

The seasonality of forage production is one of the main challenges in semi-arid regions, where environmental conditions limit agricultural productivity. One promising option is the use of elephant grass ‘BRS Capiaçu’, together with deficit irrigation. This study evaluated the impact of different irrigation depths with brackish water (50%, 75%, 100% and 125% of the reference evapotranspiration – ET 0 ) on the productive, physio...

Adopting resilient practices is crucial to balancing food production and crop sustainability in semiarid regions. Therefore, adopting systems that provide greater stocks of water, carbon, and nutrients at the soil-plant interface is crucial. The objective of this study was to assess water, carbon, and nutrient stocks in the soil-plant systems of irrigated forage crops in the semiarid region of Brazil. The study was conducted i...

Background and aims Sustainable citrus production requires nitrogen (N) management strategies that account for soil–plant nutrient interactions, particularly those affecting calcium (Ca) nutrition. In fertigated citrus orchards, strategies differing in NO₃⁻:NH₄⁺ balance and associated Ca supply affect soil chemical properties, plant nutritional status, fruit yield, and NUE. This study evaluated the effects of contrasting ferti...

Obesity and endocrine disruptors (EDs) promote endoplasmic reticulum (ER) stress, a mechanism associated with cardiovascular diseases. Among EDs, BPS is widely used in consumer products. Whether BPS promotes cardiac ER stress, either alone or combined with a high-fat diet, remains unclear. Male C57BL/6 mice were assigned to a standard chow diet (SC—15 kJ/g), SC+BPS (SCB), high-fat diet (HF—21 kJ/g), or HF+BPS (HFB), receiving...

This study evaluated the effect of N-acetylcysteine ​​on oxidative biochemistry and bone damage during the development of ligature-induced experimental periodontitis in rats. The rats were divided into three groups (n = 8/group): control, experimental periodontitis (EP), or experimental periodontitis plus daily N-acetylcysteine administration (EP + NA) (100 mg/kg/day). Periodontitis was induced by bilateral silk ligatures on t...

In the face of climate change, agricultural modelling combined with experimental research is essential for predicting yields in diverse climatic scenarios. This study calibrated, validated and applied the AquaCrop model for forage sorghum under future climate scenarios in a semi‐arid region between 2020 and 2022. Meteorological data, soil moisture, canopy cover and crop productivity were collected. Model performance was evalua...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Fire and flooding are key ecological filters that shape biodiversity and ecosystem functioning in tropical wetlands. This study investigates the combined effects of prescribed fire, flood regimes, and herbivory on the taxonomic and functional diversity of herbaceous communities in the Brazilian Pantanal, the world’s largest continuous floodplain. Using a long-term experimental design with 32 one-hectare plots distributed acros...

Lectins are carbohydrate-binding proteins involved in diverse biological processes and with increasing relevance in biotechnological applications. In this study we report the structural characterization of a lectin from the marine red alga Amansia multifida (AML). Mass spectrometry analysis revealed two major isoforms with molecular masses of 28,388 Da and 28,661 Da. The primary structure of a lectin with a molecular weight of...

The use of herbicides in modern agriculture has been the subject of ongoing debate due to their negative impacts on the environment and human health. The aim of this study was to assess the bacterial, physicochemical and genotoxicity parameters of three soil samples of public farming settlements in Petrolândia, Brazil. The bacterial resistance patterns were examined after soil exposures to a known concentration of glyphosate (...
