abnormal heterochromatin organization during vegetative growth decreased subtelomeric chromatin knob formation reduced subtelomeric chromatin knob formation 2016-07-19T12:54:47Z FYPO:0005528 midori decreased subtelomeric chromatin knob assembly decreased subtelomeric chromatin condensation A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the formation of chromatin knobs in subtelomeric regions is decreased. Chromatin knobs are highly condensed chromatin bodies formed from subtelomeric heterochromatin (observed on chromosomes 1 and 2). decreased frequency of knob-containing nuclei
