Figure 3From: Virus-derived transgenes expressing hairpin RNA give immunity to Tobacco mosaic virus and Cucumber mosaic virusSouthern blot analyses of T 2 and T 4 transgenic plants expressing hairpin RNA of TMV partial MP (A) or CMV partial Rep (B). Genomic DNA from immune (+), susceptible (-) or wild type tobacco (wt) plants was digested with Dra I, Eco RI or Eco RV, and hybridized with a radioactively labeled TMVΔMP (A) or CMVΔRep (B) probe.Back to article page
