Taxonomic tree of surveyed 38 species. Total number of genome-widely identified MCTPs in each species and the numbers of MCTPs involved in different duplication-modes were also listed. Species from different taxonomy and/or species were marked with different colors. “Total” represented total MCTP gene numbers in each species; “LD” represented local duplication, including tandem and proximal duplication; “WGD” represented whole-genome/segmental duplication; “singleton” represented genes without paralogous pairs in MCScanX; “others” represents genes other than LD, WGD and singleton; “-” means duplication mode were not estimated
