Evidence of genetic diversity within Solanum Lycopersicum L. ‘Platense’ landrace and identification of various subpopulations
(Springer Nature, 2020-06-14)
Local varieties and landraces are traditional crops that have evolved over time through adaptation to their natural and cultural environment. They are presently regarded as a valuable genetic reservoir, given that most of ...
Clinal variation along precipitation gradients in Patagonian temperate forests: unravelling demographic and selection signatures in three Nothofagus spp.
(Springer Nature, 2020-01-10)
Past demographic changes and current selection pressures determine the genetic variation displayed by Nothofagus species along rainfall gradients. Based on the diversity trends observed at candidate genes associated to ...
Structure and genetic diversity of three Calibrachoa caesia populations by ISSR markers
(ISHS, 2013-07)
Calibrachoa caesia is one of thirteen native species of the genus Calibrachoa Cerv. ex La Lave et Lexarza (Solanaceae) growing in Argentina. The genus has a high ornamental value due to the morphological variability that ...
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 ...
Genetic structure in cultivated quinoa (Chenopodium quinoa Willd.), a reflection of landscape structure in Northwest Argentina
(Springer, 2012-08)
Quinoa (Chenopodium quinoa Willd.), one of the main crops domesticated in the Andean highlands 1,000 of years ago, played an important role as a protein source. 35 germplasm accessions collected along the Northwest Argentina ...
Dynamics of genetic variability in Anastrepha fraterculus (Diptera: Tephritidae) during adaptation to laboratory rearing conditions
(BioMed Central, 2014)
Background: Anastrepha fraterculus is one of the most important fruit fly plagues in the American continent and
only chemical control is applied in the field to diminish its population densities. A better understanding ...
Distribution and genetic variation of Amblyomma triste (Acari: Ixodidae) in Argentina
(2013-09)
A study was conducted to investigate the distribution of Amblyomma triste in Argentina under the hypothesis that this tick prevails in riparian localities along the Paraná River and adjacent humid environments from 34°30′ ...
Assessing the genetic diversity of Panicum coloratum var. makarikariense using agro‐morphological traits and microsatellite‐based markers
(2015-11)
Panicum coloratum var. makarikariense is a perennial C4 grass native to South Africa with relatively good forage production under limited‐resource conditions. Genetic characterisation and breeding efforts have been scant, ...
Microsatellite analysis and marker development in garlic: distribution in EST sequence, genetic diversity analysis, and marker transferability across Alliaceae
(2018-04)
Allium vegetables, such as garlic and onion, have understudied genomes and limited molecular resources, hindering advances in genetic research and breeding of these species. In this study, we characterized and compared the ...
