Other claims from this paper (4)
- Observation Seven heterozygous knobs containing 180-bp repeats were detected in the chromosomes of all materials tested.
- Observation One heterozygous knob containing TR-1 was detected in the chromosomes of all materials tested.
- Observation The 180-bp repeat is the main contributor to knob heterozygosity compared with the TR-1 element.
- Observation One target cell in maize inbred line GB57 had two TR-1 signals on one homolog of chromosome 2L, unlike normal cells.
