e0“In maize, neocentromeres are induced by a gene or genes on Abnormal chromosome 10 (Ab10) which causes heterochromatic knobs to move poleward at meiotic anaphase”
e3“The presence of Ab10 does not affect the rate of normal chromosome movement but propels neocentromeres poleward at rates as high as 1.4 micron/min”

Other claims from this paper (8)
- Observation Neocentromeres are active from prometaphase through anaphase in maize meiosis.
- Observation Normal chromosomes move on the spindle at an average rate of 0.79 micron/min during mid-anaphase.
- Intervention effect Ab10 propels neocentromeres poleward at rates as high as 1.4 micron/min.
- Intervention effect Kinetochore-mediated chromosome movement is only marginally affected by a linked neocentromere.
- Observation Unlike kinetochores, neocentromeres associate laterally with microtubules.
- Observation Neocentromere movement is correlated with knob size.
- Mechanism Microtubule depolymerization is not required for neocentromere motility.
- Mechanism Neocentromeres are mobilized on microtubules by minus end-directed motor proteins.
