Abstract

Grafting vegetables for disease resistance has increased greatly in popularity over the past 10 years. Verticillium wilt of tomato is commonly controlled through grafting of commercial varieties on resistant rootstocks expressing the Ve1 R-gene. To mimic the grafted plant, proteomic analyses in tomato were used to identify a suitable root-specific promoter (TMVi), which was used to express the Ve1-allele in susceptible Craigella (Cs) tomato plants. The results indicate that when infected with Verticillim dahliae, race 1, the transformed plants are comparable to resistant cultivars (Cr) or grafted plants.
