Tomato is an edible and useful vegetable. Navel rot disease and low light stress are the problem in tomato cultivation. Tomato breeding is a potential cheap solution but takes longer time. Grafting technology provides instant solution like cultivating sensitive tomato (scion) grafted on resistant rootstock on non-optimal environmental conditions. DNA methylation of grafted plants might help to adapt to the adverse conditions and has become a hot point in researches concerning vegetable breeding. In this research, disease-resistant tomato cultivar "1221" was used as rootstock, while disease-sensitive tomato cultivar "Money Maker (MM)" was used as scion. After grafting, changes of genomic global DNA methylation were investigated through MSAP analysis. According to MSAP analysis, alterations of degree of DNA methylation patterns were observed, which might help graft hybrids to adapt in response to the internal and external stimuli.
