Abstract
This paper demonstrates a simple but effective use of combinatorial probes to label plant chromosomes by multicolour fluorescence in situ hybridisation (FISH). Three different DNA probes were labelled with only two different fluorophores, hybridised to somatic metaphase chromosomes of Secale cereale and Triticum aestivum, simultaneously visualised, and unequivocally distinguished in a single FISH experiment. Combinatorial labelling can augment karyotypical investigations, physical mapping of chromosomes and other analyses in plants based upon FISH.
