abnormal heterochromatin organization during vegetative growth abolished subtelomeric chromatin knob formation abolished subtelomeric chromatin knob assembly abolished subtelomeric chromatin condensation midori 2017-10-23T14:37:56Z subtelomeric chromatin knob formation abolished A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the formation of chromatin knobs in subtelomeric regions does not occur. Chromatin knobs are highly condensed chromatin bodies formed from subtelomeric heterochromatin (observed on chromosomes 1 and 2). knob-containing nuclei absent FYPO:0006260
