decreased histone H3-K14 ubiquitination at silent mating-type cassette heterochromatin during vegetative growth decreased histone H3-K14 ubiquitination at silent mating-type cassette cenH region during vegetative growth 2026-05-21T11:01:14Z A cellular process phenotype observed in the vegetative growth phase of the life cycle in which ubiquitination of lysine at position 14 of histone H3 at the cenH region in silent mating-type cassettes occurs to a lower extent than normal. cenH is a region located between mat2-P and mat3-M that is homologous to centromeric repeats, and that produces non-coding RNAs and small interfering RNAs.
