Random Distribution Pattern and Non-adaptivity of Genome Size in a Highly Variable Population of Festuca pallens

Popis výsledku v původním jazyce

Background and Aims: The spatial and statistical distribution of genome sizes and the adaptivity of genome size to some types of habitat, vegetation or microclimatic conditions were investigated in a tetraploid population of Festuca pallens. The population was previously documented to vary highly in genome size and is assumed as a model for the study of the initial stages of genome size differentiation. Methods: Using DAPI flow cytometry, samples were measured repeatedly with diploid Festuca pallens asthe internal standard. Altogether 172 plants from 57 plots (2.25 m2), distributed in contrasting habitats over the whole locality in South Moravia, Czech Republic, were sampled. The differences in DNA content were confirmed by the double peaks of simultaneously measured samples. Key Results: At maximum, a 1.115-fold difference in genome size was observed. The statistical distribution of genome sizes was found to be continuous and best fits the extreme (Gumbel) distribution with rare occu
