Potato leaf senescence affects the olfactory and feeding preferences of the green peach aphid, Myzus persicae
(Wiley, 2025)BACKGROUND: Foliar senescence is a physiological process involving the degradation of chlorophyll and proteins, with nitrogen compounds, especially amino acids, mobilised to other parts of the plant. This process enriches ... -
Total free lipids from MDR strain of Mycobacterium tuberculosis “M” reduce T cell activation and CTL activity in healthy individuals

Development of a ptp2-LAMP assay for the specific and sensitive detection of Nosema apis and its comparison with ptp3-LAMP for the detection of Nosema ceranae, in a region endemic for both microsporidium pathogens of the Western honey bee
(Elsevier, 2025)The Western honey bee plays a pivotal role in global food security as the primary commercial pollinator. The microsporidian pathogens Nosema apis and Nosema ceranae infect the bee midgut, causing nosemosis, a debilitating ... -
Characterization of two GH10 enzymes with ability to hydrolyze pretreated Sorghum bicolor bagasse
(Springer, 2025-04)In this study, we characterized two novel enzymes of the glycoside hydrolase family 10 (GH10), Xyl10 C and Xyl10E, identified in the termite gut microbiome. The activities of both enzymes were assayed using beechwood xylan, ... -
Combining linkage and association mapping approaches to study the genetic architecture of verticillium wilt resistance in sunflower
(MDPI, 2025-04)Sunflower Verticillium Wilt and Leaf Mottle (SVW), caused by Verticillium dahliae Kleb., is a globally prevalent disease affecting sunflower production. In this study, we identified a major quantitative trait locus (QTL) ... -
Transcriptomic response of male Anastrepha fraterculus (Diptera: Tephritidae) to sexual stimulation by host plant volatiles
(Elsevier, 2025-09)Anastrepha fraterculus is a major pest of fruits in South America. Previous studies revealed that males exposed to volatiles from guava, a likely ancestral host, intensify courtship behavior and increase mating success. ... -
Protection against rabies induced by the non-replicative viral vectors MVA and Ad5 expressing rabies glycoprotein
(MDPI, 2025-04)Rabies is a zoonotic viral disease that is preventable through vaccination. Effective control strategies should follow the “One Health” concept, as targeting zoonotic pathogens at their animal source is the most effective ... -
Chicken coccidiosis in peri-urban family farming in two South American countries : prevalence and circulating eimeria spp.
(MDPI, 2025-04)Family poultry production systems (FPPSs) in Chile and Argentina produce high-quality and nutritious food. However, little is known about chicken coccidiosis in these production systems. This work aimed to determine the ... -
Primeras evidencias de la inducción de androesterilidad en trigo mediante el silenciamiento post transcripcional del gen Msh1
(INTA, 2024-11)La androesterilidad, esterilidad que afecta el normal desarrollo del polen, facilita la producción de híbridos al simplificar el proceso de emasculación delas líneas parentales. La androesterilidad citoplasmática posee ... -
Frequencies of β-casein variants and their influence on genetic merit for production traits in Holstein cows
(CSIRO Publishing, 2024-12)Context: Traits considered for selection are influenced by social, consumer, and breeder demands. In the past decades, there has been increasing global interest in producing milk free from the β-casein (CSN2) A1 allele ... -
Avances en una nueva generación de algodones transgénicos
(INTA, 2024-11)El cultivo de algodón es uno de los más importantes en Argentina debido a su impacto económico y social. Su producción enfrenta dificultades en el manejo de insectos perjudiciales entre los que se destaca la presencia del ... -
Expresión de transcriptos codificados en intervalos genéticos donde mapean dos genes complementarios de resistencia a roya de la hoja de trigo identificados en Sinvalocho MA, variedad portadora de resistencia durable
(INTA, 2024-11)La roya de la hoja es causada por el hongo biótrofo Puccinia triticina y puede producir pérdidas de rendimiento entre 5-10%. Su control mediante genes de resistencia reduce los costos de producción y los daños al medio ... -
Desarrollo y aplicación de herramientas genómicas para analizar la variabilidad genética de Puccinia triticina, agente productor de la roya de la hoja de trigo
(INTA, 2024-11)La roya de la hoja del trigo es una de las enfermedades más importantes delcultivo de trigo y es producida por el hongo biótrofo Puccinia triticina. La resistencia de los cultivos frente a los hongos patógenos ha sido ... -
El comportamiento de acicalamiento de Apis mellifera hacia el ácaro Varroa destructor : Bases fenotípicas y genéticas e implicancia sobre la resistencia a la varroosis
