decreased histone acetylation during vegetative growth abnormal histone H4-K16 acetylation during vegetative growth decreased histone H4-K16 acetylation at boundary element IRC1L during vegetative growth midori decreased histone H4K16 acetylation at centromeric boundary element IRC1L during vegetative growth decreased histone H4-K16 acetylation at boundary element IRC1L during mitotic cell cycle FYPO:0005533 A cellular process phenotype observed in the vegetative growth phase of the life cycle in which acetylation of lysine at position 16 of histone H4 at the IRC1L boundary element occurs to a lower extent than normal. reduced histone H4-K16 acetylation at boundary element IRC1L during vegetative growth 2016-07-19T15:16:53Z
