Phylogenetictree o tree of PODs from Pyrus bretschenedri and Arabidopsis thaliana. The analysis utilized full-length protein sequences of the POD genes and was conducted using the Molecular Evolutionary Genetics Analysis version 7.0 (MEGA 7.0) software. The phylogenetic reconstruction was performed employing the Maximum Likelihood (ML) statistical method. Branch lines of subtrees are colored, indicating different POD subgroups
