Interaction network of BhbZIP proteins. A Search for the orthologs in Arabidopsis matching BhbZIPs. B The BhbZIP protein–protein interaction network. This network was predicted by the online software STRING. The BhbZIP proteins were shown in the red font below the Arabidopsis orthologs. Purple lines indicated experimentally validated protein interactions; green lines indicated predicted protein interactions based on gene neighborhood; blue lines indicated predicted protein interactions based on gene co-occurrence; and black lines indicated protein coexpression
