Abstract: There are obvious differences between high oleic acid rapeseed and low oleic acid rapeseed on sclerotinia sclerotiorum resistance.In order to find out the molecule mechanism,the high oleic acid rapeseed inbred line seeds 20-35 d after pollination were used as material for transcriptome analysis and iTRAQ analysis respectively in this study.The classifications associated with disease resistance were oxidative phosphorylation,plant hormone signal transduction and plant-pathogen interaction were discussed,and the relationship between differential genes and the corresponding protein were investigated too.Then real-time quantitative PCR(qPCR)analysis was used to verify the expression levels of differentially expressed genes which may be associated with disease resistance.Combined with previous study,the genes related with disease resistance were:gi|260505503(polygalacturonase inhibitory protein),gi|226346102(HSR203J-like protein)and gi|470103214(caltractin-like).And the genes of gi|297843222(binding protein),gi|18397961(2Fe-2S ferredoxin-like protein),gi|196052306(NADH dehydrogenase subunit),gi|18423437(NADH dehydrogenase(ubiquinone)1alpha subcomplex 5)and gi|297794581(kinase family protein)have obvious difference.

Key words: Sclerotinia sclerotiorum, High oleic acid rapeseed, Transcriptome, Isobaric tags for relative and absolute quantitation(iTRAQ), Real-time quantitative PCR(qPCR)
