I am working on co-expression analysis of rice gene expression data using WGCNA approach. I have obtained a number of gene clusters. I am interested to know whether the transcription factors and their target genes are members of the same cluster or not. The list of TFs have been obtained from the databases but how do I identify their target genes ? TFs are important in crop plants and any ideas on what further studies can be done with the TFs will be greatly appreciated.
