Defective mutants of cucumber mosaic virus (CMV) RNA 3, containing deletions in the 3a gene were passaged in transgenic tobacco plants expressing the CMV 3a gene. After six passages, the various progeny RNA 3 were characterized. In all but one case, the size of the deletion increased. For theNheI-fs RNA 3 mutant of the Fny-strain of CMV (with an 8 nucleotide deletion), the deletion increased in the...
To ascertain the importance of amino-terminal proximal capsid protein (CP) sequences in cell-to-cell movement, virion formation, and stabilization, two CP mutants of cucumber mosaic virus (CMV) were generated by deletion of sequences encoding CP amino acids 15–40 (ΔSal-Nru) or 26–40 (ΔSac-Nru). Wildtype CMV and CMV containing ΔSac-Nru could infect systemically four host species, although symptoms...
Cucumber mosaic virus (CMV), generated from biologically active cDNA clones of Fny-CMV RNA 1 plus 2 and Sny-CMV RNA 3, derived from the Fny-and Sny-strains of CMV, was able to infect tobacco but not squash plants systemically. In squash, viral RNA, movement protein, and coat protein all accumulated in the inoculated cotyledons. The lack of systemic infection was associated with a reduced rate of cell-to-cell...
Tobacco plants infected by the Sny strain of cucumber mosaic virus (CMV) showed chronic symptoms rather than cycles of acute disease followed by no symptoms, as seen for many strains such as Fny-CMV. The Sny-CMV 3a movement protein (MP) accumulated at 10 to 50 times the level of the Fny-CMV MP in the first few systemically infected leaves showing disease symptoms. The increased production of movement...
Tobacco plants were transformed with the cucumber mosaic cucumovirus (CMV) 3a gene and the in planta-expressed 3a protein was detected immunologically. The 3a protein was predominantly localized in a subcellular fraction corresponding to the cytosol. Two frameshift and four deletion mutants were created within the 3a open reading frame of CMV RNA 3. Five of these mutants, containing an N-terminal,...
