Characterization and comparative analysis of the genome of Puccinia sorghi Schwein, the causal agent of maize common rust
(Elsevier, 2018-03)
Rust fungi are one of the most devastating pathogens of crop plants. The biotrophic fungus Puccinia sorghi Schwein (Ps) is responsible for maize common rust, an endemic disease of maize (Zea mays L.) in Argentina that ...
In vitro selection and characterization of buffelgrass somaclones with different responses to water stress
(2017-08)
Buffelgrass is a forage grass that reproduces mainly by apomixis. In species with this reproduction mode, in vitro selection allows the incorporation of alternatives in a breeding program. The aims were to define a protocol ...

Se determinó la concentración letal 50 (CL 50) para el amitraz (Az) en poblaciones susceptibles de Rhipicephalus (Boophilus) microplus (R. (B) microplus) utilizando tela de nylon (Type 2320, Cerex Advanced Fabrics, ...
Functional analysis of Spodoptera frugiperda nucleopolyhedrovirus late expression factors in Sf9 cells
(2013-02)
We used transient expression assays to assess the function of the baculovirus Spodoptera frugiperda M nucleopolyhedrovirus (SfMNPV) homologs of Autographa californica MNPV (AcMNPV) factors involved in late gene expression ...
Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia
(BMC Plant Biology, 2014-09-17)
Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ...
Mapping QTL for resistance to new virulent races of wheat stripe rust from two Argentinean wheat cultivars
(Crop Science Society of America, 2018)
During the last two decades, new virulent and aggressive races of Puccinia striiformis Westend. f. sp. tritici (Pst) have spread worldwide, causing devastating epidemics and prompting the search for new sources of resistance ...
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
(2014-06)
Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ...
Exogenous cytokinin promotes Epipremnum aureum L. growth through enhanced dry weight assimilation rather than through changes in partitioning
(SCIENCEDOMAIN international, 2015)
Aims: Benzylaminopurine (BAP) sprays have been shown to increase leaf size and leaf appearance rate, as well as biomass accumulation in pot-grown Epipremnum aureum L. BAP-mediated enhanced growth could either be the ...
