Distribution of repetitive sequences along chromosomes revealed by self-GISH in Cucumis species. a C. sativus; b C. hystrix; c C. melo; d C. metuliferus; e C. anguria. Red signals in (a), (b), (c), (d), and (e) represent the signals produced by genomic DNA themselves. Green signals in (a), (b), (d), and (e) represent the signals produced by Arabidopsis type telomere probes. Green signals in (c) represent the signals produced by C. melo centromere probe, CentM. Scale bars = 5 μm. Arrows in (a)-2 show interstitial telomere signals. Arrows in (c)-3 and (d)-3 show the nucleolar organizing regions (NORs)
