Other claims from this paper (4)
- Observation Regenerated plants homozygous and heterozygous for the knob amplification were found.
- Observation Meiosis in regenerated plants was largely normal, with few abnormalities.
- Observation Other chromosomal changes in the cultures were consistent with BFB cycles.
- Mechanism The authors attribute the 12-F amplification to unequal crossing over.
