Characterization of BrYV amplicon-transformed Arabidopsis. (a) Southern blot analysis indicating that the cDNA of BrYV was inserted into the Arabidopsis genome. The genomic DNA of transgenic Arabidopsis plants was digested with either EcoR I or Hind III. (b) Northern blot results showing the constitutive expression of BrYV-encoded genomic RNA (gRNA) and subgenomic RNAs (sgRNAs). (c) Western blot analysis demonstrating the expression of the BrYV coat protein in lines 111 and 412.
