Potential inhibitor of viral mouvements which may confer resistance to some tobamoviruses but not to the tomato mosaic virus (ToMV) and tobacco mosaic virus (TMV). (Microbial infection) Fails to interact with the tobamovirus mouvement protein of tobacco mosaic virus (TMV). The Tm-2, Tm-2(2) and Tm-2nv alleles present in the tomato mosaic virus (ToMV/TMV)-resistant tomato cv. Craigella isolates GCR236 (AC Q71BH0), cv. Craigella GCR267 (AC Q71BG9) and cv. Yukang 2 (AC Q5MLE9), respectively confers resistance to ToMV but not the tm-2 allele present in the ToMV-susceptible tomato cv. Craigella isolate GCR26 (AC Q71BH1). Belongs to the disease resistance NB-LRR family.
