the use of nucleolar silver staining in plant cells in conditions of impaired transcription , either natural ( quiescent cells ) or induced ( actinomycin d , ethidium bromide and cordycepin treatments ) , shows that nucleoli with very low transcription rates , compared with controls , contain similar amounts of argyrophilic proteins , as well as the same structural location .
