Title Fluorescence in situ hybridization in a root tip metaphase squash of Nothoscordu Author Kar Yoong Lim Keywords alternative telomeres, Asparagales, asymmetric PCR, FISH, minisatellites, onion, Description alternative telomeres, Asparagales, asymmetric PCR, FISH, minisatellites, onion, Fluorescence in situ hybridization in a root tip metaphase squash of Nothoscordum striatum (Alliaceae) probed with concatemers of the human-type telomere motif (TTAGGG)n (biotin-labeled probe detected with cy3 avidin, red fluorescence; DAPI counterstain for DNA, blue fluorescence). The (TTAGGG)n minisatellite motif is found at chromosome ends (the telomeres). The authors showed that these motifs, and all investigated minisatellite repeats typical of eukaryote telomeres, are lost with the divergence of the genus Alllium from the rest of Alliaceae.
