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

Cytological diploidization of paleopolyploid genus Zea: Divergence between homoeologous chromosomes or activity of pairing regulator genes?

Autor: Lidia Poggio, Graciela Esther González

Publikováno v: PLoS ONE, Vol 13, Iss 1, p e0189644 (2018)

Cytological diploidization process is different in autopolyploid and allopolyploid species. Colchicine applied at the onset of meiosis suppresses the effect of pairing regulator genes resulting multivalents formation in bivalent-forming species. Colc

In maize, we studied the causes of genome size variation and their correlates with cultivation altitude that suggests the existence of adaptive clines. To discuss the biological role of the genome size variation, we focused on Bolivian maize landrace

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 (Bs), and number and seq

Se investigaron los números cromosómicos y los cariotipos de tres especies y un híbrido del género Canna, que crecen en la Argentina y también se encuentran distribuidos en el neotrópico. Mediante una tinción cromosómica convencional se anali
