Abstract Variation in genome size and knob heterochromatin content was explored in relationship to altitudinal cline and length of the vegetative cycle in northern Argentina, USA and Mexico landraces. It was considering that the decrease in DNA and h

Exploring karyotype diversity of Argentinian Guaraní maize landraces: Relationship among South American maize.

Autor: María Florencia Realini, Lidia Poggio, Julián Cámara Hernández, Graciela Esther González

Publikováno v: PLoS ONE, Vol 13, Iss 6, p e0198398 (2018)

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 communities in Misiones Provin

Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have been difficult to assess due

In the maize landraces from Northeastern Argentina inter and even intra-populational genome size variations were detected. Moreover, high variation in number, positions, percentage of heterochromatin as well in size and sequence compositions of knobs

Genetic diversity of maize landraces from lowland and highland agro-ecosystems of Southern South America: implications for the conservation of native resources

Autor: Verónica Viviana Lia, Mariana Bracco, Alexandra Marina Gottlieb, Lidia Poggio, Julián Cámara Hernández

Publikováno v: Annals of Applied Biology. 160:308-321

The North of Argentina is one of the southernmost areas of maize landrace cultivation. Two distinct centres of diversity have been distinguished within this region: Northwestern Argentina (NWA), and Northeastern Argentina (NEA). Nowadays, maize landr

Publikováno v: American Journal of Botany. 85:168-174

Twenty-one native populations (1120 individuals) of maize from Northern Argentina were studied. These populations, which belong to 13 native races, were cultivated at different altitudes (80‐3620 m). Nineteen of the populations analyzed showed B ch
