Other claims from this paper (6)
- Observation TR-1 elements occur in knobs on other maize chromosomes in different proportions relative to 180-bp repeats.
- Observation At least one chromosome 4 knob is predominantly TR-1 repeat.
- Observation Small TR-1 and 180-bp repeat clusters occur on different chromosomes, some outside obvious knob heterochromatin.
- Observation TR-1 restriction fragment fingerprints and copy number vary among maize lines and chromosomes.
- Observation TR-1 arrays up to 70 kilobases long can be interspersed with 180-bp tandem repeat arrays.
- Observation TR-1 shares two short homology segments with the 180-bp repeat.
