Zhao H, Ge J, Liao M, Wang Y, Rong X, Wang J, Yuan C, Cui Q. Complete mitochondrial genome and phylogenetic analysis of Cirriformia tentaculata (Annelida, Polychaeta, Cirratulidae) from Weihai, Shandong, China. Mitochondrial DNA B Resour 2024; 9:911-914. [PMID: 39077061 PMCID: PMC11285236 DOI: 10.1080/23802359.2024.2381783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Accepted: 07/13/2024] [Indexed: 07/31/2024] Open
Abstract
Cirriformia species usually inhabit intertidal zones and deep-sea sediments. Their accurate identification has proven to be challenging. Here, we present the complete mitochondrial genome of one Cirriformia tentaculata_Montagu 1808 specimen collected from China. The total length of the complete mitochondrial sequence of C. tentaculata is 15,516 bp and consists of 13 protein-coding genes (PCGs), 23 tRNA genes, two rRNA genes, and an A + T rich region (64.20%). All PCGs begin with the typical ATN start codon, except for cox1, which uses TTG. TAA or TAG serve as termination codons for twelve PCGs, while nad5 terminates with an incomplete codon, T. The phylogenetic tree revealed a close relationship between C. tentaculata in this study, and Cirriformia cf. tentaculata and Timarete posteria from Korea. The information will assist in the future identification and understanding of this species and offers a novel point of reference for identifying Cirriformia species, and phylogenetic studies.

The Mitochondrial Genomes of Siboglinum plumosum and Oligobrachia dogieli (Annelida: Siboglinidae) and Their Phylogenetic Analysis. Genes (Basel) 2024; 15:77. [PMID: 38254966 PMCID: PMC10815697 DOI: 10.3390/genes15010077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 12/25/2023] [Accepted: 01/03/2024] [Indexed: 01/24/2024] Open
Abstract
Frenulates are a group of sedentary Annelida within the family Siboglinidae that inhabit the ocean floor and present a unique challenge for comprehensive molecular and phylogenetic investigations. In this study, we focused on the frenulates, specifically assembling the mitochondrial genomes of Siboglinum plumosum and Oligobrachia dogieli. The phylogenetic reconstruction placed S. plumosum as a sister taxon to S. ekmani, and O. dogieli as a sister taxon to S. fiordicum, supporting the non-monophyletic nature of the genus Siboglinum. Overall, this study supports the phylogeny of the family Siboglinidae while highlighting the need for additional molecular data within frenulates.
