Intrapopulation genome size dynamics in Festuca pallens

Original language description

Background and Aims: It is well known that genome size differs among species. However, information on the variation and dynamics of genome size in wild populations and on the early phase of genome size divergence between taxa is currently lacking. Genomesize dynamics, heritability and phenotype effects are analysed here in a wild population of Festuca pallens (Poaceae). Methods: Genome size was measured using flow cytometry with DAPI dye in 562 seedlings from 17 maternal plants varying in genome size.The repeatability of genome size measurements was verified at different seasons through the use of different standards and with propidium iodide dye; the range of variation observed was tested via analysis of double-peaks. Additionally, chromosome countswere made in selected seedlings. Key Results and Conclusions: Analysis of double-peaks showed that genome size varied up to 1.188-fold within all 562 seedlings, 1.119-fold within the progeny of a single maternal plant and 1.117-fold in s
