From: Papain-like cysteine proteases in Carica papaya: lineage-specific gene duplication and expansion
a The phylogenetic tree of 155 PLCP genes of subfamily III identified in 53 plant species whose genome sequences were available in Phytozome database and papaya relative species available in Genbank. The pink color highlights the major subclades of the monocot group and the green color highlights the major subclades of the dicot group. Bootstrap values of major branches were shown. b Phylogenetic relations of the nine PLCP genes of subfamily III in papaya using the Neighbor-Joining method with 1000 replicates in the bootstrap test. Estimated ages of major duplication events leading to lineage-specific expansion of papaya PLCP genes in subfamily III were shown
