Molecular phylogeny of F. graminearum ABC transporters. The depicted phylogram was obtained by Neighbor-Joining using MEGA4 software and reflects the relationships between 54 amino acid sequences of putative ABC transporters that were extracted from the F. graminearum proteome. Results from bootstrapping with 1000 replicates are indicated when higher than 30%. Classification for subfamily uses a published nomenclature [26, 27] and is indicated by colored boxes. ALDp, adrenoleukodystrophy protein; MDR, multi drug resistance proteins; MRP, multidrug resistance-associated proteins; PDR, pleiotropic drug resistance proteins; NBD, nucleotide-binding domain; TMS, transmembrane spanning domain.
