Genome-wide expression profiling reveals transcriptional reprogramming in Fusarium graminearum by FgV1-DK21 virus infection

Using a 3′-tiling microarray covering the whole F. graminearum genes, we carried out genome-wide expression analyses of F. graminearum infected with FgV-DK21 (Mycovirus) at two different time stages (36 h and 120 h). Our study is the first report which elucidated the global alternation of the prominent cellular pathways in fungal host by FgV1-DK21 virus infection. A total of 12 chips were used for microarray. At 36 h and 120 h, total RNAs were extracted from virus free Fusarium and virus infected Fusarium with three biological replicates.
