Transcriptomic analysis of gene expression of Verticillium dahliae upon treatment of the cotton root exudates.

Based on the GO analysis results, the early stage of interaction (6 h and 12 h) were considered as the critical stage of V. dahliae-cotton interaction. Comparative transcriptomic analysis detected that 31 candidate genes response to root exudates from cotton cultivars with different level of V. dahliae resistance, 68 response to only susceptible cotton cultivar, and 26 genes required for development of V. dahliae. Collectively, these expression data have advanced our understanding of key molecular events in the V. dahliae interacted with cotton, and provided a framework for further functional studies of candidate genes to develop better control strategies for the cotton wilt disease.
