Abstract

Dictyostelium intermedium is a member of dictyostelids, the unicellular eukaryotes with a unique life cycle, including a social cycle. Despite the high diversity of dictyostelids, only five species' complete mitochondrial genome sequences were reported. This study aimed to add the D. intermedium mitochondrial genome sequence to the list. The size of this genome is 58,627 bp, with 73.99% A/T, containing 62 genes located on one strand: 41 protein-coding genes, three ribosomal RNA genes, and 18 transfer RNA genes. The 41 protein-coding genes comprised 18 oxidative phosphorylation-related, 16 ribosomal, and seven hypothetical protein-coding genes. The cox1/2 and rnl gene contained introns, similar to other species of Dictyostelium. The phylogenetic tree built based on 34 protein sequences supported the monophyletic clade of Dictyostelium and the dictyostelids' ancestor's position between the two dictyostelids orders: Dictyosteliales and Acytosteliales.
