Professor Peter Palukaitis is from Seoul Women’s University, where his current research focuses on molecular analysis of the mechanisms of resistance elicited by tobacco mosaic virus (TMV) in tobacco containing the N gene, structure-function relationships of chrysanthemum viroids, and application of resistance to multiple viruses in transgenic potato. In addition, in collaboration with colleagues in India, Italy, Spain, the UK and the USA, he is involved in research on host-virus interactions associated with disease and resistance (using cucumber mosaic virus, potato leaf roll virus and various potyviruses) and exploitation of several viruses for biotechnological applications.
