25S–18S rDNA IGS of Capsicum: molecular structure and comparison
(Springer, 2012-02)The primary and secondary structures of the intergenic spacer (IGS) between the 3′-end of 25S ribosomal RNA (rRNA) gene and the 5′-end of 18S rRNA gene are described for the cultivated chili pepper Capsicum pubescens. The ... -
A barnavirus sequence mined from a transcriptome of the Antarctic pearlwort Colobanthus quitensis
(2018-03)Because so few viruses in the family Barnaviridae have been reported, we searched for more of them in public sequence databases. Here, we report the complete coding sequence of Colobanthus quitensis associated barnavirus ... -
A beginner’s guide for FMDV quasispecies analysis: sub-consensus variant detection and haplotype reconstruction using next-generation sequencing
(Oxford Academic Press, 2020-09)Deep sequencing of viral genomes is a powerful tool to study RNA virus complexity. However, the analysis of next-generation sequencing data might be challenging for researchers who have never approached the study of viral ... -
A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
A global-temporal analysis on Phytophthora sojae resistance-gene efficacy
(Springer Nature, 2023-09-27)Plant disease resistance genes are widely used in agriculture to reduce disease outbreaks and epidemics and ensure global food security. In soybean, Rps (Resistance to Phytophthora sojae) genes are used to manage Phytophthora ... -
A novel EPSPS Pro-106-His mutation confers the first case of glyphosate resistance in Digitaria sanguinalis
(Wiley, 2022-04)BACKGROUND: Digitaria sanguinalis has been identified as a species at high risk of evolving herbicide resistance, but thus far, there are no records of resistance to glyphosate. This species is one of the most common weeds ... -
A novel real-time PCR assay for quantitative detection of Campylobacter fetus based on ribosomal sequences
(BMC, 2016-12)Background: Campylobacter fetus is a pathogen of major concern for animal and human health. The species shows a great intraspecific variation, with three subspecies: C. fetus subsp. fetus, C. fetus subsp. venerealis, and ... -
A one-year longitudinal study of enterohemorrhagic Escherichia coli O157 fecal shedding in a beef cattle herd
(Elsevier, 2019-12-01)Bovines are the primary reservoir of enterohemorrhagic Escherichia coli (EHEC) O157:H7 and the main source of its transmission to humans. Here, we present a one-year longitudinal study of fecal shedding of E. coli O157. ... -
Abate Fetel Light
(Estación Experimental Agropecuaria Alto Valle, INTA, 2010)Consideraciones sobre su comportamiento en el Alto Valle de Río Negro: Abate Fetel Light es una mutación inducida en la variedad de pera Abate Fetel, cuyo comportamiento se estudia desde 2006 en el INTA Alto Valle. Fue ... -
Acceso y uso de los recursos fitogenéticos nativos de Argentina con fines ornamentales
(Ediciones INTA, 2022)Los recursos naturales se han convertido en objeto de explotación, por lo que la biodiversidad aparece no sólo como una multiplicidad de formas de vida, sino como zonas de reserva de naturaleza, donde territorios y hábitat ... -
Accounting for competition in multi-environment tree genetic evaluations: a case study with hybrid pines
(Springer, 2021-01)A novel multi-environment competition individual-tree mixed model resulted in better fit, and greater individual narrow- and broad-sense heritabilities than the model without competition, notably for traits showing ... -
AcMNPV Core Gene ac109 Is Required for Budded Virion Transport to the Nucleus and for Occlusion of Viral Progeny
(Plos One, 2012-09)The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac109 core gene has been previously characterized as an essential late gene. Our results showed that budded virions could be detected in supernatants of ... -
Adaptation of genetically monomorphic bacteria : evolution of copper resistance through multiple horizontal gene transfers of complex and versatile mobile genetic elements
(2017-02)Copper-based antimicrobial compounds are widely used to control plant bacterial pathogens. Pathogens have adapted in response to this selective pressure. Xanthomonas citri pv. citri, a major citrus pathogen causing Asiatic ... -
AHAS Trp574Leu substitution in Raphanus sativus L.: screening, enzyme activity and fitness cost
(2018-07)BACKGROUND: Feral radish (Raphanus sativus L.) is a problematic weed that has become resistant to acetohydroxyacid synthase (AHAS) inhibitor herbicides due to the Trp574Leu mutation. An AHAS gene mutation that causes ... -
