obsolete abolished protein tyrosine phosphorylation during vegetative growth true abolished protein tyrosine phosphorylation during mitotic cell cycle FYPO:0002288 This term was made obsolete to implement a decision that protein modification terms should only include residue-specific information in cases where it is especially biologically significant, such as in histones or the RNA polymerase II CTD. In all other cases, phenotypic effects on specific modified residues should be captured in annotation extensions. FYPO:0002033 abolished peptidyl-tyrosine phosphorylation during vegetative growth midori 2013-06-13T13:37:19Z OBSOLETE. A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the phosphorylation of tyrosine residues in one or more specific proteins, or of specific protein sites, does not occur. protein tyrosine phosphorylation abolished during vegetative growth
