abnormal nucleosome positioning at stress response genes increased nucleosome occupancy at FLEX element increased nucleosome occupancy at FLEX element during mitotic cell cycle increased nucleosome occupancy at FLEX element during vegetative growth midori FYPO:0006309 2017-12-15T15:16:34Z A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy is greater than normal at promoters containing FLEX elements. Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes.
