Genomic and physiological plasticity in natural variants of commercial soybean inoculants supports the non-GMO status of base-edited inoculants
(Springer, 2025-04)The regulatory classification of genome-edited microorganisms remains a topic of debate, particularly in the agricultural sector. In this study, we analyze the genomic and physiological differences of commercial variants ... -
Reduction in acute bee paralysis virus Infection and mortality in honey bees (Apis mellifera) by RNA interference technology
(MDPI, 2025-05)In Argentina, various studies have reported the detection of multiple viruses in honey-producing and queen-rearing apiaries, with Aparavirus apisacutum, the causal agent of acute bee paralysis (ABP), demonstrating a ... -
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
(Elsevier, 2025-07)Increasing evidence highlights the role of cell wall components in the effectiveness of different Mycobacterium tuberculosis (Mtb) strains in modulating host immune response. We previously demonstrated that the outbreak ... -
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 ... -
