ABSTRACT.- Key message: Eight QTL conferring additive APR to YR were identified in wheat germplasm using GWAS. The high accuracy of GP models supports the feasibility of accelerating breeding for YR resistance. Abstract: Wheat yellow rust (YR), caused by Puccinia striiformis f. sp. tritici (Pst), is among the most devastating diseases affecting wheat worldwide. Since 2000, YR has expanded into regions where it was previously not considered an economically important disease. The deployment of YR-resistant cultivars remains the most effective and sustainable control strategy.

ABSTRACT.- This study analyzed the impact of land use and cover changes, along with climate variability, on water consumption by quantifying actual evapotranspiration ((Formula presented.)) in the Tres Cruces River basin (TCR) in Uruguay. Using Landsat 8 and 9 images from 2014 to 2024, the SAFER method (Simple Algorithm for Evapotranspiration Retrieving), applied for the first time in Uruguay, estimated (Formula presented.) for natural vegetation (grasslands and riparian forests) and commercial afforestation areas.

In the original article [1], the omission of two critical references led to a shift in the citation numbering throughout the discussion section, which significantly impacts the interpretation of the text.

ABSTRACT.- Ovine footrot has Dichelobacter nodosus as the primary pathogen, and it is characterized by its infectious and multifactorial nature, such as environmental conditions, management practices, and host susceptibility, leading to variable prevalence and economic impacts across regions. The present study investigated factors associated with footrot scores in individual sheep from a non-probabilistic sample of 60 flocks enrolled by the Uruguayan Wool Secretariat, from which 6,139 sheep had their feet clinically evaluated from 2021 to 2024. PCR was employed to confirm D.

ABSTRACT.- The intensification of irrigated rice production systems requires a comprehensive assessment of the environmental impact of pesticide use. Here, we investigated the behavior of the herbicide glyphosate (GLY) and its metabolite aminophosphonic acid (AMPA), throughout four rice rotations (continuous rice cropping (RC), ricesoybean (R-S), rice-short term pasture (R-PS) and rice-long term pasture R-PL) reflecting different agricultural intensification scenarios in a long-term experimental (LTE) site. © 2025 Elsevier B.V.

ABSTRACT.- Rice (Oryza sativa L.) is a staple food for over half of the world's population. With population growth, socioeconomic changes, and shifting consumer lifestyles, the demand for high-quality rice has surged. Understanding consumer preferences for rice quality traits is crucial for breeders to effectively address evolving market needs. Rice breeding programs assess various quality aspects, including grain shape, appearance, milling efficiency, and cooking and eating qualities.

ABSTRACT.- Among the most important sap-sucking insect pests (Hemiptera) of eucalypts are psyllids (Sternorrhyncha) and true bugs (Heteroptera). Damage inflicted to
trees by these insectsmay include significant leaf area loss, to weakening or tree death. High pest populations may affect a significant proportion of trees within commercial
stands, leading to large losses in forest productivity. Among the more than 400 species of Australian Hemiptera associated with eucalypts, eight psyllid species and

ABSTRACT.- Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by severe joint inflammation, synovial hyperplasia and degradation of the cartilage and bone in the joint. Patients with RA have an amplified T helper (Th) 1 and Th17 immune response and production of autoantibodies by autoreactive B cells. In the joint, macrophages mediate bone destruction and maintain the inflammatory process in RA.

ABSTRACT.- Changes in light conditions may affect invasiveness as they can constrain different stages of plant development during the invasion process. This is particularly true in grazed grasslands, as livestock selectively removes above-ground biomass, promoting light heterogeneity. We assessed how light intensity and quality affect the germination and growth of Eragrostis plana, one of the most invasive alien grasses of the Río de la Plata grasslands (southern Brazil, Uruguay, and eastern Argentina).
