Synergic activity of Cel8Pa β-1,4 endoglucanase and Bg1Pa β-glucosidase from Paenibacillus xylanivorans A59 in beta-glucan conversio
(Elsevier, 2020-12)In the efficient bioconversion of polysaccharides from lignocellulosic biomass, endoglucanases and β-glucosidases are key enzymes for the deconstruction of β-glucans. In this work, we focused on a GH8 endoglucanase ... -
Transgenic citrange troyer rootstocks overexpressing antimicrobial potato snakin-1 show reduced citrus canker disease symptoms
(Elsevier, 2020-12)Citrus canker is a major disease caused by Xanthomonas citri pv. citri. Snakin-1 is an antimicrobial peptide, which was previously shown to be effective against different bacterial and fungal diseases in potato, wheat and ... -
Fungicide resistance in Cercospora species causing cercospora leaf blight and purple seed stain of soybean in Argentina
(Wiley, 2020-12)Cercospora species cause cercospora leaf blight (CLB) and purple seed stain (PSS) on soybean. Because there are few resistant soybean varieties available, CLB/PSS management relies heavily upon fungicide applications. ... -
Closing the Gaps to Understand the Tick Transmission of Anaplasma marginale among Giant Anteaters (Myrmecophaga tridactyla) in Argentina
(MDPI, 2020-12)Anaplasma marginale, a well-known cattle pathogen of tropical and subtropical world regions, has been previously molecularly characterized in a giant anteater (Myrmecophaga tridactyla) from Corrientes, Argentina. Ticks or ... -
Identification and characterization of a Babesia bigemina thrombospondin-related superfamily member, TRAP-1 : a novel antigen containing neutralizing epitopes involved in merozoite invasion
(BioMed Central, 2020-12)Background: Thrombospondin-related anonymous protein (TRAP) has been described as a potential vaccine candidate for several diseases caused by apicomplexan parasites. However, this protein and members of this family have ... -
Geography as non-genetic modulation factor of chicken cecal microbiota
(Public Library of Science, 2021-01)The gastrointestinal tract of chickens harbors a highly diverse microbiota contributing not only to nutrition, but also to the physiological development of the gastrointestinal tract. Microbiota composition depends on many ... -
Bioprospecting of microbial strains for biofuel production: metabolic engineering, applications, and challenges
(BMC, 2021-01)The issues of global warming, coupled with fossil fuel depletion, have undoubtedly led to renewed interest in other sources of commercial fuels. The search for renewable fuels has motivated research into the biological ... -
Vineyard environments influence Malbec grapevine phenotypic traits and DNA methylation patterns in a clone‑dependent way
(Springer Verlag, 2021-01)Clonal selection and vegetative propagation determine low genetic variability in grapevine cultivars, although it is common to observe diverse phenotypes. Environmental signals may induce epigenetic changes altering gene ... -
Argentinian potato leafroll virus P0 protein : Novel activities for a previously known suppressor
(Wiley, 2021-02)The potato leafroll virus (PLRV) P0 protein (P0PL) is a suppressor of RNA silencing. In this study, we showed that P0 protein from an Argentinian isolate of PLRV (P0PL‐Ar) has an additional activity not described for other ... -
Role of PhoPR in the response to stress of Mycobacterium bovis
(Elsevier, 2021-02)PhoP is part of the two-component PhoPR system that regulates the expression of virulence genes of Mycobacteria. The goal of this work was to elucidate the role of PhoP in the mechanism that Mycobacterium bovis, the causative ... -
