Název v původním jazyce

Molecular and cytogenetic analysis of the biggest plant genomes

Popis výsledku v původním jazyce

The genus Fritillaria comprises species with the largest genomes so far reported for any plant, and at the same time, it provides extensive infrageneric genome size variation (30,000-127,000 Mb/C) along with surprising karyotype uniformity. The genus hasa bicontinental distribution and both diverged groups independently show a trend of increasing genome size with divergence. Here we report a very inhomogenic AT-rich satellite repeat, representing a significant part of heterochromatic chromosome regionsin the North American group which has not been found in the Eurasian Fritillaria species. To identify dispersed type of repetitive sequences most abundant in genomes of Fritillaria, we characterized about 140 kb for one species of each group with approximately equal genome size: F. imperialis (Eurasia) and F. affinis (North America).
