Galacturonosyltransferase 4 silencing alters pectin composition and carbon partitioning in tomato
(2013-04)Pectin is a main component of the plant cell wall and is the most complex family of polysaccharides in nature. Its composition is essential for the normal growth and morphology pattern, as demonstrated by pectin-defective ... -
Sunflower: a potential fructan-bearing crop?
(2015-10)Grain filling in sunflower (Helianthus annuus L.) mainly depends on actual photosynthesis, being the contribution of stored reserves in stems (sucrose, hexoses, and starch) rather low. Drought periods during grain filling ... -
Genome-wide analysis of the snakin/GASA gene family in solanum tuberosum cv. Kennebec
(2016-04)Snakin/GASA proteins have been involved in different aspects of plant growth and development although their exact role is still intriguing. All of them maintain 12 cysteines of the C-terminus in highly conserved positions ... -
Differential replication of Foot-and-mouth disease viruses in mice determine lethality
(2017-09)Adult C57BL/6J mice have been used to study Foot-and-mouth disease virus (FMDV) biology. In this work, two variants of an FMDV A/Arg/01 strain exhibiting differential pathogenicity in adult mice were identified and ... -
Draft genome sequences of two mycobacterium bovis strains isolated from beef cattle in Paraguay
(2017-07)This work reports the draft genome sequences of the Mycobacterium bovis strains M1009 and M1010, isolated from the lymph nodes of two infected cows on a beef farm in Paraguay. Comparative genomics between these strains and ... -
First complete genome sequence of potato leafroll virus from Argentina
(2017-07)In this study, we determined for the first time the complete genomic sequence of an Argentinian isolate of Potato leafroll virus (PLRV), the type species of the genus Polerovirus. The isolate sequenced came from a Solanum ... -
MicroRNA analysis of Taenia crassiceps cysticerci under praziquantel treatment and genome-wide identification of Taenia solium miRNAs
(2017-09)MicroRNAs (miRNAs) are small non-coding RNAs that have emerged as important regulators of gene expression and perform critical functions in development and disease. In spite of the increased interest in miRNAs from helminth ... -
Cestode parasites release extracellular vesicles with microRNAs and immunodiagnostic protein cargo
(2017-09)Intercellular communication is crucial in multiple aspects of cell biology. This interaction can be mediated by several mechanisms including extracellular vesicle (EV) transfer. EV secretion by parasites has been reported ... -
Effects of deletion of the ac109 gene of Autographa californica nucleopolyhedrovirus on interactions with mammalian cells
(2017-03)Baculoviruses are able to enter into mammalian cells, where they can express a transgene that is placed under an appropriate promoter, without producing infectious progeny. ORF109 encodes an essential baculovirus protein ... -
The localization of a heterologous displayed antigen in the baculovirus-budded virion determines the type and strength of induced adaptive immune response
(2017-05)In the search of strategies of presentation of heterologous antigens to elicit humoral or cellular immune responses that modulate and properly potentiate each type of response, researchers have been studying baculovirus ... -
Differential mRNA accumulation upon early arabidopsis thaliana infection with ORMV and TMV-Cg Is associated with distinct endogenous small RNAs Level
(2015-08-03)Small RNAs (sRNAs) play important roles in plant development and host-pathogen interactions. Several studies have highlighted the relationship between viral infections, endogenous sRNA accumulation and transcriptional ... -
Immunomodulatory effect of baculovirus in chickens : how it modifies the immune response against infectious bursal disease virus
(2016)Several reports have shown that baculoviruses (BVs) have strong adjuvant properties on the mammalian immune system. Recent studies of our group demonstrated the ability of BV to stimulate the innate immunity in chickens. ... -
Metabolic profile of mycobacterium smegmatis reveals Mce4 proteins are relevant for cell wall lipid homeostasis
(2016)Introduction The Mce proteins are encoded in a variable number of operons (from one to eight) in all Mycobacterium species. A role in the transport of host and mycobacterial lipids has been demonstrated for some Mce proteins ... -
Isolation and clinical sample typing of human leptospirosis cases in Argentina
(2016)Leptospira typing is carried out using isolated strains. Because of difficulties in obtaining them, direct identification of infective Leptospira in clinical samples is a high priority.Multilocus sequence typing (MLST) ... -
The key role of the largest extant Neotropical frugivore (Tapirus terrestris) in promoting admixture of plant genotypes across the landscape
(2016)The historical and contemporary loss of large-bodied frugivores has disrupted many plant-disperser mutualisms, with potentially profound consequences for plants. Although several aspects of seed dispersal by megafrugivores ... -
Phylogeographic analysis of the 2000-2002 foot-and-mouth disease epidemic in Argentina
(2016)Foot-and-mouth disease (FMD) is a highly transmissible disease of hooved livestock. Although FMD has been eradicated from many countries, economic and social consequences of FMD reintroductions are devastating. After ... -
Allelic differences in a vacuolar invertase affect Arabidopsis growth at early plant development
(2016)Improving carbon fixation in order to enhance crop yield is a major goal in plant sciences. By quantitative trait locus (QTL) mapping, it has been demonstrated that a vacuolar invertase (vac-Inv) plays a key role in ... -
Polymorphisms of 20 regulatory proteins between Mycobacterium tuberculosis and Mycobacterium bovis
(2016)Mycobacterium tuberculosis and Mycobacterium bovis are responsible for tuberculosis in humans and animals, respectively. Both species are closely related and belong to the Mycobacterium tuberculosis complex (MTC). M. ... -
Evaluation of different heterologous prime-boost immunization strategies against Babesia bovis using viral vectored and protein-adjuvant vaccines based on a chimeric multi-antigen
(2016)Protection against the intraerythrocytic bovine parasite Babesia bovis requires both humoral and cellular immune responses. Therefore, tailored combinations of immunogens targeted at both arms of the immune system are ... -
Identification and characterization of contrasting sunflower genotypes to early leaf senescence process combining molecular and physiological studies (Helianthus annuus L.)
