We also observed extensive differential coexpression between genes within the same metabolic pathways. By integrating the Arabidopsis regulatory network into our analysis, we identified several transcription factors that may be regulators of differential coexpression during plant immune responses. Importantly, many of those genes have similar average expression levels between normal plant growth and pathogen infection but have different coexpression partners. Genes that were frequently involved in differential coexpression tend to be related to plant immune responses. Overall, we found that differential coexpression was a common phenomenon of plant immunity. Syringae through differential coexpression analysis. Using time-series microarray data of Arabidopsis thaliana infected with Pseudomonas syringae, we analyzed Arabidopsis defense responses to P. Recently, differential coexpression analysis has been developed to study the rewiring of gene networks through microarray data, which is becoming an important complement to traditional differential expression analysis. Plant defense responses to pathogens involve massive transcriptional reprogramming.
