First report of bicolour FISH of Berberis diaphana and B. soulieana reveals interspecific differences and co-localization of (AGGGTTT)3 and rDNA 5S in B. diaphana.BACKGROUND
 Most Berberis species lack cytological data, and bicolour fluorescence in situ hybridization (FISH) has never been performed on Berberis.  via FISH using oligonucleotide telomere probes for (AGGGTTT)3 and 5S rDNA (41 bp) for the first time.


 FISH physical mapping of B. diaphana suggested that (AGGGTTT)3 and rDNA 5S co-localize at the 6th pair of chromosomes.  Our results provide information that may contribute to future studies on the physical assembly of the Berberis genome and the evolution of rDNA and telomere FISH patterns in Berberis.
