abnormal 7-methylguanosine cap hypermethylation
A cellular process phenotype observed in the vegetative growth phase of the life cycle in which hypermethylation of the 7-(mono)methylguanosine (m(7)G) cap structure at the 2' position of the guanosine residue to form a 2,2,7-trimethylguanosine cap structure is abnormal.
