Plants of impatiens (Impatiens holstii) with symptoms of leaf deformation and stunting from a commercial greenhouse in Minnesota were infected with tobacco streak virus (TSV). The virus was similar in biologic and physical properties to previously described strains of TSV and reacted positively with antisera to the TSV-HF, TSV-NC, and TSV-R strains of TSV.
