normal histone H3-K9 methylation at centromere during vegetative growth normal spatial extent of histone H3-K9 methylation during vegetative growth normal spatial extent of histone H3-K9 methylation at peri-centromere during vegetative growth 2023-03-07T13:58:43Z normal histone H3-K9 methylation spreading at peri-centromere during vegetative growth A cellular process phenotype observed in the vegetative growth phase of the life cycle in which methylation of lysine at position 9 of histone H3 occurs over the same portion of the peri-centromere as normal (i.e. indistinguishable from wild type). vw253
