(a) Somatic chromosome and nuclei of Allium fistulosum after DAPI staining and fluorescence in situ hybridization with labelled non-coding satellite sequences (green signals for Alexa 488) and 45S rDNA (red signals for rhodamine) using conventional detection systems. (b) A. fistulosum chromosomes after in situ hybridisation with the same probes. The biotinylated non-coding satellite probe was detected with QD 565 streptavidin conjugate (green signal, arrowed) yielding only very weak and few signals. In contrast, the conventional antibody detection of 45s rDNA loci (in red) resulted in a strong hybridization signal.
