Chytrid fungi infecting Arctic microphytobenthic communities under varying salinity conditions [PDF]

Scientific Reports
This study aimed to investigate the presence and diversity of fungal parasites in Arctic coastal microphytobenthic communities. These communities represent a key component in the functioning of Arctic trophic food webs.

Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River. [PDF]

Ecol Evol
This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

RNAi reveals a unique set of kinesins mediating chloroplast motility in the giant cytoplasm of Bryopsis (Ulvophyceae), a coenocytic green alga. [PDF]

J Phycol
Abstract RNA interference (RNAi) is a powerful tool for protein knockdown and is widely used in model animals and plants. Here, we implemented RNAi in Bryopsis, a green feather alga that develops a coenocytic thallus >10 cm in length without cytokinesis.

Broad Ecological Niche in Seashore Lichens Emerges From a Stable, Selective Association With Generalist Algal Symbionts. [PDF]

Ecol Evol
In mutualistic symbioses, partner flexibility often broadens the host ecological niche. We found a stable association between littoral lichens and their algal symbionts along a natural salinity gradient, suggesting that the broad ecological niche can be facilitated by association with a single generalist symbiont.

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.

A comparative test of the gamete dynamics theory for the evolution of anisogamy in Bryopsidales green algae [PDF]

Royal Society Open Science, 2021
Gamete dynamics theory proposes that anisogamy arises by disruptive selection for gamete numbers versus gamete size and predicts that female/male gamete size (anisogamy ratio) increases with adult size and complexity.

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.

A Minority of Desert Cyanobacteria and Algae Is Responsible for the Bulk of CO₂ Fixation. [PDF]

Physiol Plant
ABSTRACT Cyanobacteria and algae are the major photosynthetic organisms in deserts because they survive desiccation, high solar radiation and extreme temperature fluctuations better than other plants. Under favourable conditions, desert cyanobacteria and algae evidently photosynthesise.

Phylogenomic analysis of the chloroplast genome of the green-tide forming macroalga Ulva intestinalis Linnaeus (Ulvophyceae, Chlorophyta)

Mitochondrial DNA. Part B. Resources, 2021
Ulva intestinalis Linnaeus 1753 (Ulvophyceae, Chlorophyta) is a marine green macroalga that is distributed on coasts of the Yellow Sea and the Bohai Sea in China. Here, the complete chloroplast genome of U.

The macroalgal culture collection in Kobe University (KU-MACC) and a comprehensive molecular phylogeny of macroalgae based on the culture strains

Applied Phycology, 2022
The Kobe University Macroalgal Culture Collection (KU-MACC), as a section of the Kobe University Research Center for Inland Seas, distributes cultures of macroalgae to the public under the umbrella of the National BioResource Project of Ministry of ...
