Natural variation in nucleolar dominance reveals relationship between nucleolus organizer chromatin topology and rRNA gene transcription in Arabidopsis

In genetic hybrids, nucleolus formation on chromosomes inherited from only one parent is the epigenetic phenomenon, nucleolar dominance. By using Arabidopsis suecica, the allotetraploid hybrid of Arabidopsis thaliana and Arabidopsis arenosa, natural variation in nucleolar dominance was found to occu...
