Abstract
The soil fungus Fusarium spp, is the main cause of apple replant disease in China. The M9T337 apple rootstock was used to investigate the molecular responses to Fusarium solani infection using transcriptome analysis. We identified 667 differentially expressed genes in F. solani-infected rootstocks, of which 543 were up-regulated and 124 were down-regulated. These differentially expressed genes included receptor kinases, transcription factors, and genes involved in the production and transport of metabolites. In particular, secondary metabolites can enhance plant resistance to pathogens while P450s and UDP-glycosyltransferase play a unique roles in the defense response.
