Abstract:
Two different resistant and susceptible Chinese cabbage varieties to black rot were used as test materials.Transcriptomics and bioinformatics methods were used to investigate gene expression at different times after infection by the black rot pathogen，in order to provide reference for the breeding of new varieties of Chinese cabbage resistant to black rot disease.The results showed that a total of 37 228 genes were detected and expressed by transcriptomics，of which 34 752 were known genes and 2 476 new genes were predicted.There were 997 differential genes in the three treatments of the resistant variety and 1 593 differential genes in the three treatments of the susceptible variety.There were 157 differential genes in the six comparison groups.Pathway enrichment analysis revealed that these genes were mainly involved in benzoxazinoid biosynthesis，circadian rhythm-plant，amino acid metabolism，and so on.Cluster analysis screened out three key genes for disease resistance，which were up-regulated in the disease-resistant group and down-regulated in the susceptible group.The genes were identified as protein-serine/threonine kinase，and so on.
