Major Pericentromere Repeat Organization at Interphase Is Disrupted in nrpe1 and drd1 But Not nrpd1 Mutants.
DNA-FISH of 5S genes (red) and 180-bp centromeric repeats (green) (left panel).
Organization pattern of pericentromeric regions analyzed by FISH using the 180-bp centromere repeat (green) and the BAC F28D6 (red) DNA probes (middle panel).
Immunostaining followed by DNA-FISH performed respectively with an antibody recognizing the A. thaliana centromeric histone H3, HTR12 (red), and 180-bp centromeric repeats (green) (right panel). In all panels, DNA was visualized by DAPI (gray) and size bars indicate 5 μm.
