A genetic approach to the species problem in wild potato
Camadro, Elsa Lucila; Erazzu, Luis Ernesto; Maune, Juan Federico; Bedogni, Maria Cecilia (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 ... -
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
Poulsen Hornum, Anabela; Camadro, Elsa Lucila (Springer Nature, 2020-10-07)Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ... -
Genetic and biochemical biomarkers in the macrophyte Bidens laevis L. Exposed to a commercial formulation of endosulfan
Pérez, Débora Jesabel; Lukaszewicz, Germán; Menone, Mirta Lujan; Amé, María Valeria; Camadro, Elsa Lucila (Wiley, 2014-09)Previous studies in the wetland macrophyte Bidens laevis L have demonstrated that the insecticide endosulfan induces a high frequency of somatic chromosome aberrations in anaphase–telophase (CAAT) but no DNA changes as ... -
Genomic relationships between hexaploid Helianthus resinosus and diploid Helianthus annuus (Asteraceae)
Miranda Zanetti, Julieta; Greizerstein, Eduardo Jose; Camadro, Elsa Lucila; Poverene, María Mónica; Echeverria, Mercedes; Poggio, Lidia; Carrera, Alicia Delia (Springer, 2014-05)Genus Helianthus comprises diploid and polyploid species. An autoallopolyploid origin has been proposed for hexaploid species but the genomic relationships remain unclear. Mitotic and meiotic studies in annual Helianthus ... -
Morphological and molecular variability of wild diploid and polyploid populations of Chrysolaena flexuosa (Sims) H. Rob: relevance for ornamental breeding
Echeverria, Maria Lis; Camadro, Elsa Lucila (Elsevier, 2020-01)Chrysolaena flexuosa is a South American species of ornamental interest, whose variability has not been explored. The objective of this work was to perform joint analyses of morphological and molecular traits in seven ... -
Over time variation in microsatellite (ssr) patterns in a natural wild potato population from northwest Argentina.
Leofanti, Gabriela; Camadro, Elsa Lucila; Erazzu, Luis Ernesto (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 = ... -
Pollen‐mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense Bitter under experimental field conditions in Argentina
Capurro, Mauricio Antonio; Camadro, Elsa Lucila; Masuelli, Ricardo Williams (Wiley, 2013-12)The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber‐bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ... -
Variation patterns in natural populations of wild potatoes along Quebrada de Inca Cueva, northwestern Argentina
Ispizua, Veronica Nilda; Camadro, Elsa Lucila; Clausen, Andrea Martina (Springer, 2015-02)Wild potato species, Solanum infundibuliforme Phil. (ifd) (2n = 2x = 24), S. gourlayi Hawkes (grl) (2n = 4x = 48) and presumed grl–ifd hybrids (2n = 4x = 48) were collected from a narrow gorge known as Quebrada de Inca ...
