Abstract

A chimeric vector was constructed to express cucumber mosaic virus (CMV) satellite (Sat) RNA and coat protein (CP). Transgenic lines of tobacco cultivar G-140 expressing CP and Sat-RNA were obtained; these lines had high resistance to CMV. Fifty to 70% of the transgenic plants were symptomless 90 days after inoculation with 25-50 micrograms/ml of CMV. Resistance was about twice that conferred by the Sat-RNA or the CP gene alone in transformed plants.
