Cytomolecular comparative maps of the diploid genome of R. bulbosa (A) and the tetraploid genome of N. jankae (B) based on CCP analysis. Uppercase A to X mark 24 conserved genomic blocks defined here by A. thaliana BAC clones (www.arabidopsis.org). Chromosome in situ localizations of 5S and 35S rDNA probes are shown in Supplemental Figure S4.
