abolished protein modification during vegetative growth abnormal histone phosphorylation during vegetative growth abolished histone phosphorylation during vegetative growth 2013-09-04T16:01:32Z histone phosphorylation abolished during vegetative growth A cellular process phenotype observed in the vegetative growth phase of the life cycle in which histone phosphorylation does not occur. All histone phosphorylation may be affected, or phosphorylation of specific sites on specific histones may be abolished. midori FYPO:0002592 histone phosphorylation absent during vegetative growth abolished histone phosphorylation during mitotic cell cycle
