Other claims from this paper (9)
- Observation GISH showed high genomic affinity between maize and Z. mays subsp. parviglumis and subsp. mexicana.
- Observation Zea mays subsp. huehuetenanguensis DNA showed a lower affinity to maize chromosomes.
- Mechanism The pattern of hybridization with Zea mays subsp. huehuetenanguensis DNA suggested intergenomic restructuring between the parental genomes of maize.
- Observation Zea diploperennis DNA showed lower genomic affinity to maize chromosomes, especially at knob regions.
- Observation Zea perennis DNA gave hybridization signals on four maize chromosome pairs.
- Observation Zea perennis DNA gave a hybridization signal in only one chromosomal arm on two maize chromosome pairs.
- Observation Four maize chromosome pairs did not hybridize with Zea perennis DNA.
- Mechanism Maize has a parental genome not shared with Z. perennis (hypothesis).
- Mechanism The absence of hybridization signals in all maize knobs indicates that these heterochromatic regions were lost during Z. perennis genome evolution.
