Signals of the oligonucleotide probe for the telomere sequence of Arabidopsis thaliana were observed at both ends of all chromosomes. Chromosomes with tHC displayed the signals directly on the tHC.
Figure b: FISH signals (yellow-green, see arrow heads) of the telomere sequence of Arabidopsis thaliana on polytene chromosomes of Phaseolus coccineus. Chromosomes are counterstained with DAPI and displayed here in grey or red. Representative examples of signals of the telomere sequence located terminal on chromosomes A, B and I. The scale bar represents 10 µm.
