Sub-networks of genes up-regulated in the Arabidopsis genome in response to full-length CaLCuV AC2 protein. The diagrams illustrate sub-networks of genes that may be co-regulated in Arabidopsis, in response to the transcription activation domain of AC2. Sub-networks I (A), V (B) and IV (C) were up-regulated at one dpi. Highly linked genes in sub-network IV (D) were up-regulated at two dpi. The sub-networks were selected from the network analysis presented in (Additional file 6: Figure S1).
