Over time variation in microsatellite (ssr) patterns in a natural wild potato population from northwest Argentina.
(Crop Science Society of America, 2021-02-26)The common potato, Solanum tuberosum L. (2n = 4x = 48), has 100–200 related wild taxonomic species endemic to the Americas, which constitute invaluable sources of genetic diversity. They form a polyploid series with 2n = ... -
Overall evaluation of artichoke leftovers: Agricultural measurement and bioactive properties assessed after green and low-cost extraction methods
(Elsevier, 2021-06)Globe artichoke is rich in nutrients and phenolic compounds. However, nearly 85% of its biomass is discarded following harvest. To propose a scalable and economically attractive process for the revalorization of this ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
Overexpressed proteins in hypervirulent clade 8 and clade 6 strains of Escherichia coli O157:H7 compared to E. coli O157:H7 EDL933 clade 3 strain
(2016)Escherichia coli O157:H7 is responsible for severe diarrhea and hemolytic uremic syndrome (HUS), and predominantly affects children under 5 years. The major virulence traits are Shiga toxins, necessary to develop HUS and ... -
The overexpression of antifungal genes enhances resistance to rhizoctonia solani in transgenic potato plants without affecting arbuscular mycorrhizal symbiosis
(Elsevier, 2019-10)The biological control of fungal diseases through the use of genetically modified (GM) plants could decrease the input of chemical pesticides. To overcome possible losses in potato (Solanum tuberosum) yield because of ... -
Overexpression of glycine-rich RNA-binding protein in tomato renders fruits with higher protein content after cold storage
(2018)Glycine-rich RNA-binding proteins (GR-RBPs) are involved in RNA processing and also some of them are output signals of the circadian clock. In tomato, one GR-RBP gene family (LeGRP1) is composed by three highly homologous ... -
Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants
(Wiley-Blackwell, 2008-05)Snakin‐1 (SN1), a cysteine‐rich peptide with broad‐spectrum antimicrobial activity in vitro, was evaluated for its ability to confer resistance to pathogens in transgenic potatoes. Genetic variants of this gene were cloned ... -
Overview of the role of Shiga toxins in porcine edema disease pathogenesis
(Elsevier, 2018-06)Shiga toxin-producing Escherichia coli (STEC) have been implicated as the cause of enterotoxemias, such as hemolytic uremic syndrome in humans and edema disease (ED) of pigs. Stx1 and Stx2 are the most common types found ... -
OVGM el caso de los cultivos transgénicos
(2019-07)Para abordar la temática de cultivos modificados genéticamente (OVGM), en los distintos eslabones de la cadena de los sectores agroalimentario y agroindustrial, actúan representantes de instituciones, organismos, empresas, ... -
Ovine abortion by Neospora caninum: first case reported in Argentina
(Springer Verlag Germany, 2019-09-04)Purpose The aim of this study was to describe for the first time a natural case of ovine abortion associated with Neospora caninum in a flock with reproductive losses in Argentina. Materials and Methods The analyzed ... -
Ovinos y alambres, paisaje cultural. Del pastizal natural a la insustentabilidad de la ganadería ovina en Santa Cruz
(Convenio FLACAM – Universidad Nacional de Lanús, 2009-07)El hombre y la ganadería ovina, principal actividad agropecuaria de Santa Cruz desde fines del siglo XIX, han modelado el árido paisaje de la provincia, dándole una característica común a las extensas planicies: miles de ... -
Oviposition and olfactometry response of codling moth (Cydia pomonella) to quince (Cydonia oblonga) cultivars
(Wiley, 2023-03)Quince (Cydonia oblonga Miller) is one of the common hosts of the codling moth, Cydia pomonella L. Knowledge of the chemical ecology of codling moth is based on its behaviour against apples and pears but not quince. Here, ... -
Oviposition substrate location by the invasive woodwasp Sirex noctilio: the combined effect of chemical cues emitted by its obligate symbiont Amylostereum areolatum and different host-tree species
(Wiley, 2023-06)BACKGROUND: Sirex noctilio is an invasive forest wasp that affects pines and can result in severe economic losses. The use of semiochemicals offers an opportunity to develop sensitive and specific capturing systems to ... -
