The mitochondrial genome of the deep-sea tubeworm Paraescarpia echinospica (Siboglinidae, Annelida) and its phylogenetic implications

Abstract

(2018) The mitochondrial genome of the deep-sea tubeworm Paraescarpiaechinospica (Siboglinidae, Annelida) and its phylogenetic implications, Mitochondrial DNA Part B, 3:1, 131-132,

A new Lamellibrachia species and confirmed range extension for Lamellibrachia barhami (Siboglinidae, Annelida) from Costa Rica methane seeps

“…At these seeps, two species of Lamellibrachia have been noted, L. barhami at 1,800 meters (Levin et al 2012) and an unidentified Lamellibrachia at 1,000 meters (Levin et al 2015). We combine newly generated DNA data for Lamellibrachia samples from these sites with previously published DNA data (Braby et al 2007;Cowart et al 2014;Kobayashi et al 2015;Kojima et al 2001Kojima et al , 2006Li et al 2015Li et al , 2017McMullin et al 2003;Miglietta et al 2010;Sun et al, 2018) and confirm that there is a previously undescribed species of Lamellibrachia, which we describe here. This new species has a sister group in the Atlantic (Gulf of Mexico) and the biogeography of Lamellibrachia is discussed.…”

“…The Lamellibrachia phylogeny should also be considered in the context of the phylogeny of Siboglinidae (Rouse 2001;Sun et al 2018). In the Sun et al analysis (2018), generated with 13 mitochondrial genes and two ribosomal RNA genes, all sequenced seep-dwelling Vestimentifera (Lamellibrachia, Escarpia, Seepiophila, and Paraescarpia) formed a grade with respect to a vent-dwelling clade (Riftia, Ridgeia, Oasisia, Tevnia).…”

“…Molecular analyses. Alignments of the newly generated sequences and available sequence data from GenBank for the two genes presented in Table 1 (published in the most recent siboglinid phylogenies [Braby et al 2007;Cowart et al 2014;Kobayashi et al 2015;Kojima et al 2001Kojima et al , 2006Li et al 2015Li et al , 2017McMullin et al 2003;Miglietta et al 2010;Sun et al 2018]) were performed using MAFFT with default settings (Katoh & Standley 2013) and concatenated with SequenceMatrix v.1.6.7 (Gaurav et al 2011). For those specimens with mitochondrial genomes available on GenBank, 16S and COI genes only were downloaded prior to alignment and concatenation.…”

Genomic, transcriptomic, and proteomic insights into the symbiosis of deep-sea tubeworm holobionts

“…In the present study, we sequenced the endosymbiont genome, metatranscriptome, and metaproteome of the siboglinid tubeworm Paraescarpia echinospica (the holobiont) inhabiting cold seeps in the South China Sea of the West Pacific Ocean [16, 17]. As the first integrated genomic, transcriptomic, and proteomic analysis of cold-seep tubeworm, the present study aimed to decipher the interdependence between the host and symbiont with particular emphases on how the symbiont uses various metabolic pathways to generate energy, how the host and symbiont cooperate in nutrient provisions, and how the two partners regulate each other.…”

A new record of Lamellibrachia columna (Siboglinidae, Annelida) from cold seeps off New Zealand, and an assessment of its presence in the western Pacific Ocean

“…Alignments of the newly generated sequences and available sequence data from GenBank for COI and 16S (Table 1) published in the most recent siboglinid phylogenies (Black et al 1997;Braby et al 2007;Cowart et al 2014;Kobayashi et al 2015;Kojima et al 2001;Li et al 2017;Li et al 2015;McCowin and Rouse 2018;McMullin et al 2003;Miglietta et al 2010;Sun et al 2018), including sequences for Lamellibrachia columna from the type locality (Lau Back Arc Basin), were performed using MAFFT with default settings (Katoh and Standley 2013) and concatenated with SequenceMatrix v.1.6.7 (Gaurav et al 2011). For species that showed very little variation in COI (L. anaximandri, L. cf.…”
