ERAP1 and PDE8A are downregulated in cattle protected against bovine tuberculosis
(Karger, 2017-12)Bovine tuberculosis (bTB) is a zoonotic disease caused by Mycobacterium bovis that is responsible for significant economic losses worldwide. In spite of its relevance, the limited knowledge about the host immune responses ... -
Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding
(The American Phytopathological Society, 2017-11)Sclerotinia head rot (SHR) is one of the most serious constraints to sunflower (Helianthus annuus L. var. macrocarpus) production worldwide. Here, we evaluated the response to SHR in a sunflower inbred panel from a large ... -
Leptospira species molecular epidemiology in the genomic era
(Elsevier, 2017-10)Leptospirosis is a zoonotic disease which global burden is increasing often related to climatic change. Hundreds of whole genome sequences from worldwide isolates of Leptospira spp. are available nowadays, together with ... -
Achiote (Bixa orellana L.) : a natural source of pigment and vitamin E
(Springer, 2017-05)Commercialization of agricultural products, including seeds and its derived products, represents an important economic source for developing countries. Natural colorants obtained from the seeds of achiote plant (annatto) ... -
Contrasting metabolic profiles of tasty Andean varieties of tomato fruit in comparison with commercial ones
(Wiley, 2018-08)BACKGROUND The fruits of most commercial tomato cultivars (Solanum lycopersicum L.) are deficient in flavour. In contrast, traditional ‘criollo’ tomato varieties are appreciated for fruit of excellent organoleptic quality. ... -
EcXyl43 β-xylosidase: molecular modeling, activity on natural and artificial substrates, and synergism with endoxylanases for lignocellulose deconstruction
(Springer, 2018-08)Biomass hydrolysis constitutes a bottleneck for the biotransformation of lignocellulosic residues into bioethanol and high-value products. The efficient deconstruction of polysaccharides to fermentable sugars requires ... -
Mycobacterium bovis ESAT-6, CFP-10 and EspC antigens show high conservation among field isolates
(Elsevier, 2018-07)ESAT-6, CFP-10 and EspC are virulence factors that have been extensively assayed for bovine and human tuberculosis diagnosis due their potent T-cell inducing activities. While polymorphisms of ESAT-6 and CFP-10 were analyzed, ... -
Phylogenetic analysis of ORF viruses from five contagious ecthyma outbreaks in Argentinian goats
(2018-06)Orf virus (ORFV) is the etiological agent of Contagious Ecthyma (CE) disease that mainly affects sheep, goats, wild ruminants, and humans with a worldwide distribution. To date, only two strains from Argentinian sheep have ... -
Arabidopsis phenotyping through geometric morphometrics
(Oxford University Press, 2018-07)Background: Recently, great technical progress has been achieved in the field of plant phenotyping. High-throughput platforms and the development of improved algorithms for rosette image segmentation make it possible to ... -
Novel biotechnological platform based on baculovirus occlusion bodies carrying Babesia bovis small antigenic peptides for the design of a diagnostic enzyme-linked immunosorbent assay (ELISA)
