  1. Populus v1.1 protein ID is given together with information on the closest homologue in Arabidopsis. The last column gives the number of modules (and in parenthesis the number of genes) regulated by the factor in our systems biology-based network and in the co-expression network, respectively. Transcription factors in our systems biology-based network that are not in the co-expression network are marked in bold.
