Fig. 1.

Number and localization of 35S rDNA sites (green fluorescence) and 5S rDNA sites (red fluorescence) in diploid and tetraploid Allium species (a, c, e, g, i, k) and idiograms of analyzed Allium species with localization of 35S rDNA, 5S rDNA, NORs, and positive CMA₃ bands indicated (b, d, f, h, j, l): A. moly (a, b); A. fistulosum (c, d); A. sativum (e, f); A. oreophilum (g, h); A. karataviense (i, j); A. porrum (k, l). Only one chromosome from the homologous chromosome pair is presented in idiograms. A bracket under the chromosome in the idiograms means that there was polymorphism in the rDNA sites chromosomal organization. Bar 10 μm
