e0“inter-specific interactions leading to wheat-origin NOR dominance results not only on the silencing of rye origin NOR loci, but dominant NORs are also modified in their transcriptional activity and interphase organization.”

Other claims from this paper (5)
- Observation Dominant wheat NORs were up-regulated in the wheat-rye addition line.
- Observation Perinucleolar ribosomal chromatin knobs were nearly transcriptionally silent, unlike intranucleolar condensed rDNA.
- Observation The wheat-rye addition line had significantly fewer wheat-origin perinucleolar rDNA knobs.
- Observation The heterochromatic fraction of dominant wheat NORs diminished in the addition line.
- Observation Dominant wheat NORs changed in transcriptional activity and interphase organization.
