  RNA transcripts from Spe-1 linearised PMTV-T RNA 3 cDNA clone were translated in wheat germ extract system. Two major translation products of 19.7K and 65K correspond to the predicted translation products of RNA 3: 19.7K produced by coat protein and 65K by read-through of translation termination codon. The mean density of the coat protein band was 3.253 as determined by Whole Band analysis of different exposures of autoradiographs. Similarly, the mean density of the boat protein plus read-through protein band was 0.209. This gives a ratio of 0.064 for the density of the coat protein plus read-through protein: coat protein. However, there are three methionine residues in the coat protein and 8 in the coat protein plus read-through protein. Normalising for this gives a ratio of 0.024 for amount of coat protein plus read-through protein: coat protein. In other words -2.4 percent of the ribosomes which reach the coat protein gene termination codon suppress the termination and go on to produce coat protein plus read-through protein.

  None of the 29 soybean cultivars and 40 germplasm lines tested were found immune to two isolates of soybean mosaic potyvirus (SMV-S1 and SMV-P1). Malakand-96 was the only cultivar found highly resistant to both S1 and P1 isolates. Swat-84, Bryan, Hobbit-87, Kingsay, Lugan, Sherman and Harper-87 were resistant to S1 and P1 whereas Rincondita was resistant to S1 and moderately resistant to P1 isolate. Similarly, Clark, Nare, NARC-V and Wahab-93 were resistant to P1 but not to S1 isolate. Wahab-93, Kharif-93, Ajmeri, Hodgson, Mid-Spray, Full-Walter, NARC-II, NARC-IV, NARC-VI, Clark and Nare were moderately resistant to S1 whereas Kharif93, Ajmeri, Hodgson, Full-Walter, NARC-Il, NARC-IV, Rincondita, Mid-Pharoah, NARC-VI and Winchester were moderately resistant to P1 isolate. William, Rawal-I, Mid-Pharoah, Bass, NARC-lll, NARC-I, NARC-V and Winchester were susceptible, to SMV-S1 whereas William, Rawal-I, Mid-Spray, Bass, NARC-I and NARC-III were susceptible to P1, Weber-84 was highly susceptible to both isolates of SMV. Among 40 soybean lines, GC-81083-63, GC-81084-51, GC-80072-2-6, AGS-253 and AVRDC-12, AVRDC-13 and AVRDC-15 were highly resistant to both isolates of SMV. Lines GC-81075-44, GC-81090-108, GC-81084-147, GC-81090-10, AGS-85, AGS-249, AVRDC-10, AGS-297, AVRDC-7 were resistant to S1 and P1 isolates whereas L-85-2308, AVRDC-5, AVRDC-14, were resistant to S1 and moderately resistant to P1 isolate. Line L-77-1863 was resistant to P1 but moderately resistant to S1 isolate. Similarly, GC-81080-13, GC-82117-8, AGS-154, L-88-8502, AVRDC-3, AVRDC-4, AVRDC-8 were moderately resistant to S1 and P1 isolates and AVRDC-11, GC-81084-134, GC-8108441, GC-81080-36, GC-81090-94, AVRDC-2, AVRDC-6 were moderately resistant to only P1 isolate. Ten soybean lines were susceptible and 3 highly susceptible to Si whereas 4 lines were susceptible and only one line was highly susceptible to P1 isolate.
