Circular map of the P. globosa mtDNA and phylogenetic analysis of haptophyte species. (A) Circular map of the mtDNA of P. globosa strain CNS00066. Genes were colored according to the functional categories listed in the index below the map. The GC content is indicated on the inner circle. The repeat regions (repeat 1 and repeat 2) is in gray. Genes showed inside and outside the circle are transcribed clockwise and counter-clockwise, respectively. (B) Phylogenetic tree of haptophyte species based on 13 mitochondrial proteins (ATP6, ATP9, COX1, COX2, COX3, COB, NAD1, NAD2, NAD3, NAD4L, NAD4, NAD5, and NAD6). Phylogenetic tree was reconstructed on the IQ-TREE web server (Trifinopoulos et al., 2016). Numbers at the branches represent aBayes support/ultrafast bootstrap support (%), respectively. Our strains were shown in bold.
