Multiple Losses of MSH1, Gain of mtMutS, and Other Changes in the MutS Family of DNA Repair Proteins in Animals [PDF]
Genome Biology and Evolution, 2021 Abstract MutS is a key component of the mismatch repair (MMR) pathway. Members of the MutS protein family are present in prokaryotes, eukaryotes, and viruses. Six MutS homologs (MSH1–6) have been identified in yeast, of which three function in nuclear MMR, while MSH1 functions in mitochondrial DNA repair.

Phylogeography of Cold Water Soft Coral Alcyonium spp. (Anthozoa, Octocorallia: Alcyonacea) Between South America and the West Antarctic Peninsula [PDF]
Ecology and EvolutionThe Antarctic marine environment has a unique geologic and climatic history that has contributed to the evolution of high species diversity. Given the current trend of environmental warming, understanding the history of Antarctic species is crucial for ...

Comprehensive phylogenetic reconstruction of relationships in <i>Octocorallia (Cnidaria</i>: <i>Anthozoa</i>) from the Atlantic ocean using <i>mtMutS</i> and <i>nad2</i> genes tree reconstructions [PDF]
, 2012 Abstract. Despite being an abundant group of significant ecological importance the phylogenetic relationships of the Octocorallia remain poorly understood and very much understudied. We used 1132 bp of two mitochondrial protein-coding genes, nad2 and mtMutS (previously referred to as msh1), to construct a phylogeny for 161 octocoral specimens from the ...

Efficacy of the 28S rDNA barcode in differentiating Caribbean octocorals [PDF]
Biodiversity Data JournalThe ecological landscape of Caribbean reefs is rapidly changing as octocorals fill the void left by declining scleractinian populations. Effective molecular barcodes are necessary to accurately identify these octocorals and monitor this shifting ...

Three new species of the sea fan genus Muricea (Cnidaria, Octocorallia, Plexauridae) from the northwest region of Mexico [PDF]
ZooKeys, 2023 Twenty-one nominal species of Muricea have been reported in the Eastern Pacific with nine of them reported in the Mexican Pacific. We describe three new species of Muricea: Muricea ambarae sp. nov. and Muricea cacao sp.

A next generation approach to species delimitation reveals the role of hybridization in a cryptic species complex of corals [PDF]
BMC Evolutionary Biology, 2019 Background Our ability to investigate processes shaping the evolutionary diversification of corals (Cnidaria: Anthozoa) is limited by a lack of understanding of species boundaries.

Mitogenomic phylogenetic analyses of Leptogorgia virgulata and Leptogorgia hebes (Anthozoa: Octocorallia) from the Gulf of Mexico provides insight on Gorgoniidae divergence between Pacific and Atlantic lineages [PDF]
Ecology and Evolution, 2019 The use of genetics in recent years has brought to light the need to reevaluate the classification of many gorgonian octocorals. This study focuses on two Leptogorgia species—Leptogorgia virgulata and Leptogorgia hebes—from the northwestern Gulf of ...

A unique horizontal gene transfer event has provided the octocoral mitochondrial genome with an active mismatch repair gene that has potential for an unusual self-contained function [PDF]
BMC Evolutionary Biology, 2011 Background The mitochondrial genome of the Octocorallia has several characteristics atypical for metazoans, including a novel gene suggested to function in DNA repair.
