The complete mitochondrial genome of Clydonella sawyeri (Amoebozoa, Discosea, Vannellida)

Abstract

We describe the complete sequence and organization of the mitochondrial genome from a brackish-water amoeba Clydonella sawyeri (Amoebozoa, Discosea, Vannellida). The circular mitochondrial DNA of this species has 31,131 bp in length and contains 17 protein-coding genes, 2 ribosomal RNAs, 21 transfer RNAs and 13 open reading frames. Length and gene content distinguish mitochondrial genome of Clydonella sawyeri from the mitochondrial genomes of other Amoebozoa species.

A Comparative Characterization of the Mitochondrial Genomes of Paramoeba aparasomata and Neoparamoeba pemaquidensis (Amoebozoa, Paramoebidae)

“…This is consistent with the high percentage of A + T content in the nucleotide composition of PCGs as well as in other mt genomes of Amoebozoa (Bondarenko et al. ,b,c, ; Burger et al. ; Greninger et al.…”

“…2013b; Bondarenko et al. ,b,c). Like in other amoebozoan mt genomes, the bias of the nucleotide composition toward A and T bases leads to the predominance of certain codons and amino acids in proteins (Table ).…”

“…This is the average size for the amoebozoan mt genome; it is little shorter than those of myxomycetes and dictyostelids but longer than those of vannellids (Bondarenko et al. ,b,c). Within Dactylopodida, this genome is a little shorter than N. pemaquidensis mt genome (Tanifuji et al.…”

“…The mitochondrial genome of P. aparasomata has GC content 24.8% (Table ), which is a relatively low level, typical for amoebozoan mt genomes (Bondarenko et al. ,b,c; Ogawa et al. ; Pombert et al.…”

“…Mitochondrial genome analysis is a powerful instrument for evolutionary studies, and the dataset on the mitochondrial genomes of amebae is slowly growing in taxonomic coverage (Bondarenko et al. ,b,c, ; Fučikova and Lahr ; Greninger et al. ; Pombert et al.…”
