Figure 1

The distribution of IGS-homologous satellite repeats. (A) FISH signals (red) obtained with probe derived from Hba0007F24, containing tomato rDNA (red arrow head). Bar, 10 μm (B) FISH signal (red) obtained from heterologous rDNA probe, pTa71, for wheat 25-18S rDNA (red arrow head). Bar, 10 μm (C) FISH signals (green) obtained with probe, pIGS, for type I subrepeat of rDNA (arrow head). Bar, 10 μm (D) FISH signal on DNA fibers prepared from S. lycopersicum with pTa71 (green) and pIGS (red) probes. IGS homologous satellite repeat (arrow) and rDNA array were detected (arrow head).
