Using fluorescence in situ hybridization, we located ribosomal DNA loci on prometaphase chromosomes of the diploid species Brassica rapa and Brassica oleracea and their amphidiploid Brassica napus. Based on comparisons of chromosome morphology and hybridization patterns, we characterized the individual B. napus rDNA loci according to their presumed origins in the Brassica A and C genomes. As reported in other studies, the sum of rDNA loci observed on B. rapa (AA genome) and B. oleracea (CC genome) chromosomes was one greater than the total number of loci seen in their amphidiploid B. napus (AACC). Evidence is presented that this reduction in B. napus rDNA locus number results from the loss of the smallest A genome rDNA site in the amphidiploid.Key words: Brassica, fluorescence in situ hybridization, ribosomal DNA, rDNA.

Karyotype analysis of cells has been in use for many years and has led to the causative genetic change in numerous clinical syndromes, including trisomy 21, Klinefelter, Turner, Prader-Willi and Angelman syndromes. The resolution of the test depends on the degree of condensation of the chromosomes in the karyotype, but even at high resolution (> 800 bands per haploid set) the changes identified are in the order of 5 Mb of DNA.  Fluorescence in situ hybridization (FISH) bridges the gap between the relatively low resolution of karyotype analysis and the very high resolution of DNA analysis. With FISH it is possible to identify smaller changes in individual cells. The size of the change identified correlates with the size of the probe, which vary from 120 kb to 600 kb in size. FISH is widely used to confirm deletions or duplications identified by newer methods, such as array analysis.   This review contains 8 figures, 3 tables, and 25 references.
