Karyotypes of blue-flowered flaxes with relatively large chromosomes. a – L. stelleroides (sect. Stellerolinum); b, c – members of sect. Dasylinum: diploid L. hirsutum subsp.hirsutum (b) and tetraploid L. hirsutum subsp. anatolicum; d – L. narbonense (sect.Linum). Chromosomes are arranged according to their sizes. Inverted DAPI- staining of chromosomes are shown in shades of gray. The positions of rDNA loci revealed by FISH are shown in colored insertions bellow the karyotypes: 35S rDNA – green signals and 5S rDNA – red signals. Scale bar – 5 μM
