    • Location of the 5′ termini of tobacco necrosis virus strain D subgenomic mRNAs 

      Offei, S.K.; Coutts, Robert H.A. (1996-01)
      Northern blot analysis of double-stranded (ds) RNA from bean-leaf tissue infected with tobacco necrosis virus strain D (TNV-D) detected the 4 kb genomic RNA and two subgenomic RNAs of about 1.5 kb and 1.2 kb; RNA extracted ...

    • Molecular variation of Potato yellow vein virus isolates 

      Offei, S.K.; Arciniegas, N.; Guzmán, M.; Müller, G.; Salazar, L.F.; Coutts, Robert H.A. (2004-04-01)
      To evaluate the variation of Potato yellow vein virus from potato fields, 12 isolates were collected from Colombia and one was collected from Peru. Double-stranded RNA was extracted from the plants and used as a template ...

    • Subcellular location and expression of tobacco Necrosis necrovirus p7a protein 

      Drouzas, A.D.; Offei, S.K.; Coutts, Robert H.A. (1996-06)
      A putative movement protein (p7a) of tobacco necrosis Necrovirus, strain D (TNV-D), produced in Escherichia coli using an expression vector, was used to raise an antiserum. Immunoblot analysis using this antiserum showed ...

    • The tobacco necrosis virus p7a protein is a nucleic acid-binding protein 

      Offei, S.K.; Coffin, R.S.; Coutts, Robert H.A. (1995-06)
      The two centrally located open reading frames (ORFs) of necroviruses may, by analogy with the similarly located and related ORFs of carmoviruses, be expected to have a function in virus movement in plants. In the case of ...
