Detailed network representations for ARF synteny network communities among angiosperm genomes. a Species composition for each of the 25 network communities. Blue-colored cells depict the presence of ARF syntelogs in the different species. The 25 network communities were identified using CFinder at k = 3. b Detailed visualization for each of the ARF synteny network communities. Nodes in different colors represented different plant lineages, and the node shapes represented different ARF subfamilies (Groups I through VI). Selected basal lineages including Vitis vinifera (sister to other rosids), Amaranthus hypochondriacus (sister to asterids), and Amborella trichopoda (the basal angiosperm) were depicted as red nodes in the communities. Each network community was presented following the ‘ARF clades’-‘number of nodes’-‘number of connections’ nomenclature system and some communities contain genes from multiple ARF groups
