pubmed:abstractText |
The gene (cp) encoding the coat protein (CP) of cucumber mosaic virus (CMV) strain WL (CMV-WL, which belongs to CMV subgroup II) was custom polymerase chain reaction (CPCR)-engineered for expression as described by Slightom [Gene 100 (1991) 251-255]. CPCR amplification was used to add 5'- and 3'-flanking NcoI sites to the CMV-WL cp gene, and cp was cloned into the expression vector, pUC18cpexp. This CMV-WL cp expression cassette was transferred into the genome of tobacco (Nicotiana tabacum cv. Havana 423) via the Agrobacterium T-DNA transfer mechanism. R0 plants that express the CMV-WL cp gene were subcloned, propagated, and challenge-inoculated with CMV-WL. Several R0 plant lines showed excellent protection against CMV-WL infection; however, plants found to accumulate the highest CP levels did not show the highest degree of protection. Thus in our case, CP levels appear not to be a useful predictor of the degree of protection. Plants from the best protected CMV-WL cp gene-expressing R0 tobacco lines were also inoculated with CMV strains belonging to the other major CMV subgroup (subgroup I), CMV-C and CMV-Chi, and compared in a parallel experiment with a transgenic tobacco plant line that expresses the CMV-C cp gene. Plants expressing the CMV-WL cp gene appeared to show a broader spectrum of protection against infection by the various CMV strains than plants expressing the CMV-C cp gene.
