Abstract

Agrobacterium-mediated transfer from a binary vector was used to produce transgenic Nicotiana tabacum plants that expressed coat protein of the plant virus, alfalfa mosaic virus (AMV). Expression levels of the chimeric gene, which was under the control of the cauliflower mosaic virus 19S promoter, were determined in primary transformed plants, in the progeny from self-fertilization and in the progeny from crosses to normal tobacco. RNA transcripts that were of the expected size as well as a protein of the Mr and antigenicity of AMV coat protein accumulated in the transgenic plants. Plants that expressed the highest levels of coat protein developed fewer primary infections following inoculation with two strains of AMV and developed systemic infection slower than did plants that did not express coat protein. Resistance was specifically against virions of the AMV strains. AMV RNA and the unrelated virus, tobacco mosaic virus, were as infectious on progeny that expressed coat protein as they were on progeny that did not. The relationship between the virus resistance expressed by these transgenic plants and that observed in virus cross-protection is discussed.

Keywords: alfalfa mosaic virus, cross-protection, transgenic tobacco, virus coat protein, virus resistance
