- ... RNA-dependent RNA polymerase activities were measured in healthy and tobacco mosaic virus (TMV)-infected tomato plants, to investigate the possibility that altered activity might be involved in the operation of the Tm-I gene for resistance to TMV. Healthy, susceptible and resistant plants had similar levels of enzyme activity. Infection with TMV strain 0, which is inhibited by Tm-I, caused a 2-fol ...
