Mitochondrial mRNA oligocitydylation occurs in Chlorophyceae and Ulvales but not Bryopsidales or Trebouxiophyceae. [PDF]

J Phycol
Abstract Mitochondrial mRNAs in the green algal class Chlorophyceae have non‐template 3' oligo‐cytosine‐rich additions, also known as oligo(C), polycitydylation, or poly(C) “tails.” These oligonucleotide additions are believed to be unique to green algal mitochondria, as none have been observed in any other organism.

Extensive diversity of Symbiochlorum-related algae from environmental sequences and culture strains supports the description of the new family Symbiochloraceae (Ulvophyceae, Chlorophyta). [PDF]

J Phycol
Abstract The genus Symbiochlorum, initially described from a single strain isolated from a coral in the South China Sea, was shown to be a sister lineage of Ignatius within the green algal order Ignatiales. Its significant phylogenetic divergence from Ignatius raises the possibility of its classification as a new family.

Nutrient-driven growth and microbiome shifts in the brown alga Sargassum fluitans III. [PDF]

J Phycol
Abstract Since 2011, holopelagic Sargassum has been accumulating in a region of the tropical Atlantic now referred to as the Great Atlantic Sargassum Belt (GASB). Among the hypothesized contributors to these accumulations are the increased inputs of nitrogen (N) and phosphorus (P) in the tropical Atlantic Ocean.

18S rDNA gene metabarcoding of microeukaryotes and epi‐endophytes in the holobiome of seven species of large brown algae

Journal of Phycology, Volume 59, Issue 5, Page 859-878, October 2023., 2023
Abstract Brown algae (Phaeophyceae) are habitat‐forming species in coastal ecosystems and include kelp forests and seaweed beds that support a wide diversity of marine life. Host‐associated microbial communities are an integral part of phaeophyte biology, and whereas the bacterial microbial partners have received considerable attention, the microbial ...

NAMBER: A biotic index for assessing the ecological quality of mesophotic biogenic reefs in the northern Adriatic Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 3, Page 298-311, March 2023., 2023
Abstract The aim of the present study was to propose a biotic index (North Adriatic Mesophotic BiogEnic Reefs, NAMBER) suitable for assessing the ecological quality of the mesophotic biogenic reefs of the northern Adriatic continental shelf based on photographic sampling.

Potential role of submerged macrophytes for oxic methane production in aquatic ecosystems

Limnology and Oceanography, Volume 67, Issue S2, Page S76-S88, November 2022., 2022
Abstract Methane (CH4) from aquatic ecosystems contributes to about half of total global CH4 emissions to the atmosphere. Until recently, aquatic biogenic CH4 production was exclusively attributed to methanogenic archaea living under anoxic or suboxic conditions in sediments, bottom waters, and wetlands.

Fingerprinting Arctic and North Atlantic Macroalgae with eDNA – Application and perspectives

Environmental DNA, Volume 4, Issue 2, Page 385-401, March 2022., 2022
Macroalgae are key primary producers in Arctic and North Atlantic coastal ecosystems and tracing their fate is important to understand their role in higher trophic levels and carbon sequestration. Here, we study the application and perspectives in applying metabarcoding methods for this purpose.

Exhaustive reanalysis of barcode sequences from public repositories highlights ongoing misidentifications and impacts taxa diversity and distribution

Molecular Ecology Resources, Volume 22, Issue 1, Page 86-101, January 2022., 2022
Abstract Accurate species identification often relies on public repositories to compare the barcode sequences of the investigated individual(s) with taxonomically assigned sequences. However, the accuracy of identifications in public repositories is often questionable, and the names originally given are rarely updated.

The underexplored potential of green macroalgae in aquaculture

Reviews in Aquaculture, Volume 14, Issue 1, Page 5-26, January 2022., 2022
Abstract Green macroalgae (Chlorophyta) currently represent a residual fraction (<1%) of global seaweed biomass production landings. In turn, red (Rhodophyta) and brown (Ochrophyta) macroalgae dominate the remaining percentage of aquaculture production, exceeding 32 million tonnes per annum.

Phylogenomic analysis restructures the ulvophyceae

Journal of Phycology, Volume 57, Issue 4, Page 1223-1233, August 2021., 2021
Here, we present new transcriptome sequencing data from seven species of Dasycladales (Ulvophyceae) and a phylogenomic analysis of the Chlorophyta with a particular focus on Ulvophyceae. We have focused on a broad selection of green algal groups and carefully selected genes suitable for reconstructing deep eukaryote evolutionary histories.
