The genetic heterogeneity of the N protein gene and the intergenic region (IGR) of the S RNA from tomato spotted wilt virus (TSWV) isolates, collected in Bulgaria, were compared with isolates from other parts of the world. The results substantiated the highly conserved nature of the N protein. Twenty six independent sequences revealed only seven variable(More)
We examined the resistance phenotype of a large number of transgenic tobacco plants originating from 12 commercial (Nicotiana tabacum) cultivars expressing the sense form of the nucleoprotein (N) gene of L3, a Bulgarian isolate of tomato spotted wilt virus (TSWV). The analysis revealed that transgenic plants are completely protected against the homologous(More)
