Análisis cromosómico del híbrido arachis pintoi x a. repens (leguminosae) mediante citogenética clásica y molecular
Pucciarello, Ornella; Ortíz, Alejandra Marcela; Fernández, Aveliano; Lavian, Graciela L. (Sociedad Argentina de Botánica, 2013)El análisis cariotípico fue realizado en las especies parentales Arachis pintoi y A. repens, y el híbrido interespecífico. Las tres entidades presentan la misma fórmula cariotípica (18m+2sm) y un par de cromosomas ... -
Cytogenetic evidences on the evolutionary relationships between the tetraploids of the section rhizomatosae and related diploid species (arachis, leguminosae)
Ortíz, Alejandra Marcela; Robledo Dobladez, Germán Ariel; Seijo, José Guillermo; Montenegro Valls, José Francisco; Lavia, Graciela Inés (The Botanical Society of Japan, 2017)Rhizomatosae is a taxonomic section of the South American genus Arachis, whose diagnostic character is the presence of rhizomes in all its species. This section is of particular evolutionary interest because it has three ... -
Genomic characterisation of arachis porphyrocalyx (valls & C.E. Simpson, 2005) (leguminosae) : multiple origin of arachis species with x = 9
Silvestri, María Celeste; Ortíz, Alejandra Marcela; Robledo, Germán Ariel; Montenegro Valls, José Francisco; Lavia, Graciela Inés (Pensoft, 2017)The genus Arachis Linnaeus, 1753 comprises four species with x = 9, three belong to the section Arachis: Arachis praecox (Krapov. W.C. Greg. & Valls, 1994), Arachis palustris (Krapov. W.C. Greg. & Valls, 1994) and Arachis ... -
rDNA loci and heterochromatin positions support a distinct genome type for ‘x = 9 species’ of section arachis (arachis, leguminosae)
Silvestri, María Celeste; Ortíz, Alejandra Marcela; Lavia, Graciela Inés (Springer, 2014)Most species of the genus Arachis (Leguminosae; 80 spp.) are diploid with x = 10 and only four species have x = 9 chromosomes. Three of these x = 9 species belong to section Arachis and are morphologically and chromosomally ...
