Sclerotinia disease, caused by Sclerotinia sclerotiorum, is one of the most serious plant diseases in China. Research on the mechanism of disease resistance to S. sclerotiorum will help solve control problems. In this study, near-isogenic lines were first used in combination with the proteomic technique. A comparison of protein expression profiles in a susceptible line with those in a resistant line during the interaction of adult Brassica napus with S. sclerotiorum resulted in the identification of 20 important proteins related to disease resi...
