FIGURE 3

Multicollinearity of seven mtDNAs of genus Phaeocystis members. (A) The genomes were aligned using Mauve 2.3.1. Each colored block indicates a region of synteny among the seven genomes. The block a contain cox1-trnG-UCC-rps3-trnR-UCU-trnI-GAU-atp9-trnC-GCA-atp6-trnM-CAU-trnD-GUC-nad4 -trnL-UAA-nad2-cob-trnM-CAU gene cluster, block b contain trnT-UGU-nad3-trnM-CAU-atp8-trnR-ACG-trnS-UGA gene cluster, and the block c contain trnW-UCA-nad1-rps14-trnN-GUU-trnF-GAA-cox2-trnV-UAC-rps12-trnH-GUG-trnY-GUA-nad6-trnQ-UUG-trnL-UAG-rpl16-nad4L-trnE-UUC-trnP-UGG gene cluster, and the block d contain rrnL-atp4-cox3-rrnS gene cluster, and the block e contain nad5 gene. (B) Comparison of genome organization and gene order among the genomes. The square brackets indicated the region of synteny among the genomes. Lines connecting blocks indicated putative homology. Compared with P. globosa, P. antarctica have the additional tRNA gene trnE-UUC, which is labeled by an asterisk (*). (C) The mitochondrion genomes content and synteny of strain CNS00069 and strain Pg-G(A) compared to that of strain CNS00066, respectively.
