abnormal nucleosome positioning at stress response genes abnormal nucleosome positioning at stress response genes during vegetative growth FYPO:0003812 midori A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome positioning is abnormal near the promoter regions of genes that are expressed in response to stress. Nucleosome positioning is the ordering of successions of nucleosomes into regular arrays so that nucleosomes are positioned at defined distances from one another. 2014-09-12T15:35:00Z abnormal nucleosome occupancy at stress response genes abnormal nucleosome positioning at stress response genes during mitotic cell cycle abnormal nucleosome spacing at stress response genes abnormal nucleosome positioning at protein-coding gene
