Relevancia del número y composición de secuencias de los knobs (DAPI-FISH) y su utilidad en la caracterización de accesiones de maíz y teocintle.Relevance of number and sequence composition of Knobs in the characterization of Maize and Teosinte
(Soc Mexicana Fitogenetica, 2013-05)
Los knobs o nudos cromosómicos son bloques heterocromáticos que se pueden encontrar en 34 posiciones cromosómicas diferentes en maíz (Zea mays ssp. mays) y teocintle (Zea mays ssp. parviglumis, Zea mays ssp. mexicana, Zea ...
Knobs number variability in Argentine Andean maize populations (races Amarillo Grande y Garrapata)
(University of Illinois, 2013)
In this work we studied six populations belonging to two races of maize native of northwestern Argentina (NOA) in order to analyze the variation respect to the number of heterochromatic blocks (knobs), using fluorescent ...
Are cytological parameters of maize landraces (Zea mays ssp. mays) adapted along an altitudinal cline?
(Springer Tokyo, 2018-03)
The Northwestern Argentina (NWA) highland region is one of the southernmost areas of native maize cultivation. We studied variations of different cytological parameters, such as DNA contents, presence/absence of B chromosomes ...
Exploring karyotype diversity of Argentinian Guaranímaize landraces: Relationship among South American maize
(Public Library of Science, 2018-06)
In Argentina there are two different centers of maize diversity, the Northeastern (NEA) and the Northwestern (NWA) regions of the country. In NEA, morphological studies identified 15 landraces cultivated by the Guaraní ...
Intra-specific variation in genome size in maize: Cytological and phenotypic correlates
(Oxford University Press, 2016-12)
Genome size variation accompanies the diversification and evolution of many plant species. Relationshipsbetween DNA amount and phenotypic and cytological characteristics form the basis of most hypotheses thatascribe a ...
Karyotypical studies of two maize races from Northeast Argentine (NEA): DAPI-banding and Fluorescent In Situ Hybridization (FISH)
(University of Illinois, 2013-03)
Knobs heterochromatic blocks occur in all Zea species with 2n = 20, varying in size and number across maize races and their wild relatives (Kato, Mass. Agric. Exp. Stn. Bull.635: 1-185, 1976; McClintock et al., Colegio de ...
