Title
Four Loci on Abnormal Chromosome 10 Contribute to Meiotic Drive in Maize
Evelyn N Hiatt; R Kelly Dawe Genetics 2003. doi:10.1093/genetics/164.2.699
Other claims from this paper (6)
- Observation At least four chromosomal regions contribute distinct functions to meiotic drive.
- Mechanism Only one neocentromere activating region is sufficient to move many knobs.
- Observation An Ab10 locus promoting recombination in structural heterozygotes was localized.
- Observation The suppressor of meiotic drive 3 mutation identified another independent function required for meiotic drive.
- Intervention effect Loss of either new function abolished meiotic drive.
- Intervention effect Neocentromere activity and the Ab10 recombination effect were unaffected by loss of either function.
