Abstract
Thermally denatured DNA of 11 species of Cichorieae (Compositae) was allowed to renature at 69° C in 0.8 M Na+. Two distinct fractions of repetitive DNA (fast: ∼105 repetitions, intermediate: ∼103 repetitions) were found in all species. The remaining (slow) fraction comprises 26 to 58% of the genome. The relative amounts of fast and intermediate fractions maintain constant proportions to the slow fraction except for saltatory changes, especially halvings in species with reduced genome sizes.
