Complete mitochondrial genome of the freshwater bryozoan Pectinatella magnifica (Phylactolaemata: Plumatellida) assembled from next-generation sequencing data

Abstract

The complete mitochondrial genome of the freshwater bryozoan Pectinatella magnifica was sequenced. The circular mitochondrial genome is 17,539 bp and consists of 13 protein-coding, two ribosomal RNA, and 22 transfer RNA genes (GenBank accession no. MG546680). The Bayesian comparative analysis of molecular evolution rates revealed no acceleration of the mitochondrial DNA (mtDNA) evolution of P. magnifica . Results of maximum likelihood analysis showed that this species clustered with other species of the phylum Bryozoa.

“… Maximum Likelihood phylogenetic tree based on a data matrix of 16 genes comprising 28 ctenostomes, 9 cheilostomes from Orr et al., 2021 (branch collapsed) and the phylactolaemate bryozoan Pectinatella magnifica (from Fuchs et al., 2009 ; Gim et al., 2018 ; Waeschenbach et al., 2009 ) as an outgroup to root the phylogenetic tree (see Table A2 ). Values on internal nodes correspond to ML bootstrap support (1000 replicates) and posterior probabilities for BI (based on the last 75% of trees) respectively.…”

“…As a result, the atp8 gene was excluded from our final data matrix, together with 18S and 28S of Terebripora sp. The remaining sequences of these 27 samples were combined with published sequences of the ctenostome Monobryozoon ambulans (Schwaha et al., 2024 ), nine cheilostome species (Orr et al., 2021 ) and the phylactolaemate Pectinatella magnifica as outgroup (Fuchs et al., 2009 ; Gim et al., 2018 ; Waeschenbach et al., 2009 ; Table A2 ).…”

“…Penetrantia clionoides is the sister taxon to the Penetrantia parva complex (Figure 2).
