Other claims from this paper (5)
- Observation Two repeat classes differed in neocentromere formation capacity.
- Mechanism At least two repeat-specific activators control neocentromere motility in trans.
- Mechanism Microtubule dynamics contributed little to neocentromere movement despite taxol.
- Mechanism Authors suggest maize knob repeats and binding proteins coevolved for preferential recovery.
- Mechanism Neocentromere-mediated drive is proposed to explain persistence of interstitial repeat arrays.
