Mitogenome features and phylogenetic analysis of red algae, Grateloupia cornea (Rhodophyta, Halymeniales)

open access: closedJournal of Genetics
The mitogenome is an important tool for taxonomic and evolutionary investigation. Here, a few complete mitogenomes of red algae have been reported. We have reported the complete mitogenome sequences of Grateloupia cornea Okamura, 1913 (Rhodophyta, Halymeniales). The genome is 30,595 bp in circumference, and has a strongly biased [AT] = 66.9%.

Characterization and production of tetraspore-derived seedlings of Grateloupia lanceolata (Halymeniales, Rhodophyta) in northeastern China

open access: closedPhycologia, 2012
In this study, Grateloupia lanceolata, newly recorded from northeastern China, was classified on the basis of morphology and rbcL sequence analysis and also raised in a laboratory to evaluate the feasibility of producing tetraspore-derived seedlings. Analysis of the rbcL sequence showed the samples to be monophyletic with G.

Collections of the invasive speciesGrateloupia turuturu(Halymeniales, Rhodophyta) from Tasmania, Australia

open access: closedPhycologia, 2006
Abstract Intertidal collections of morphologically variable red algal blades from Bicheno on the east coast of Tasmania, Australia, during two consecutive excursions (January 2004, 2005) were strongly reminiscent of alien populations of Grateloupia turuturu collected by the authors in Rhode Island, USA.

Insights into the Rare Mediterranean Endemic Kallymenia spathulata: DNA Phylogenies Resolve This Species as Halymeniaceae (Halymeniales) Rather than Kallymeniaceae (Gigartinales), with the Proposal of Felicinia spathulata comb. nov.

open access: closedCryptogamie, Algologie, 2018
Recently, DNA phylogenies resulted in the transfer of some species of the halymeniacean genus Aeodes, namely A. orbitosa and A. ulvoidea, to the genus Pachymenia leaving the former supposedly as a monotypic genus based on the type species, A. nitidissima. Nevertheless, that work overlooked the presence of A.

Complete mitochondrial genome of the marine red algaGrateloupia angusta(Halymeniales)

Mitochondrial DNA, 2013
The first complete mitochondrial genome (27,943 bp) of the halymenialean red alga, Grateloupia angusta, was sequenced. The circular mitogenome contains 47 genes, including 26 protein-coding, 19 tRNA and 2 rRNA genes. The rps3 and rpl16 genes are overlapped by 7 bp.

The introduced seaweed Grateloupia turuturu (Rhodophyta, Halymeniales) in two Mediterranean transitional water systems

Botanica Marina, 2011
Abstract Lagoon environments are particularly subject to the intro-duction, either accidental or voluntary, of alien species thatmay cause biological pollution. On the basis of morpholog-ical data and molecular analyses ( rbc L and mitochondrial cox 2- cox 3 spacer sequences) we confirmed the taxonomicidentity (previously only hypothesised) of ...

Invasive or not? The case of Grateloupia turuturu (Rhodophyta, Halymeniales) in the Northern Ionian Sea (Mediterranean Sea)

Marine Pollution Bulletin, 2020
It has been predicted that Grateloupia turuturu, native of the cold-temperate waters of Japan, is one of the most invasive marine species considered as a threat to global marine biodiversity. However, few studies have been carried out to assess the extent of its spread worldwide. Its seasonal dynamics in the Mar Piccolo of Taranto, a transitional water

PHYLOGENETIC AND BIOGEOGRAPHIC AFFINITIES OF THE HALYMENIALES AND RHODYMENIALES (RHODOPHYTA) FROM THE GULF OF MEXICO

Journal of Phycology, 2000
Generic and species concepts within the red algal assemblages Halymeniales and Rhodymeniales are discussed for taxa inhabiting the western Gulf of Mexico. Two principal biogeographic assemblages occur: an off‐shore deep‐water group (including Coelarthrum cliftonii, Halymenia spp., Botryocladia spp., Gloiocladia) representing remnants of a Tethyan ...
