Primary productivity coupled to oxic methane production in coastal waters of southern China

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Oxic methane (CH4) production (OMP) occurs in diverse oxygenated surface waters worldwide. However, phytoplankton‐driven OMP in natural marine environments remains poorly documented. During a research cruise in the highly productive southern East China Sea, we measured OMP by incubating phytoplankton‐rich surface waters and found that CH4 ...

Molecular characterization of eukaryotic algal communities in the tropical phyllosphere based on real-time sequencing of the 18S rDNA gene

BMC Plant Biology, 2018
Backgroud Foliicolous algae are a common occurrence in tropical forests. They are referable to a few simple morphotypes (unicellular, sarcinoid-like or filamentous), which makes their morphology of limited usefulness for taxonomic studies and species ...

Symbiotic Versatility in Action: Trebouxia Diversity Expands the Niche of the Lichen Xanthoria parietina

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Xanthoria parietina associates with an unexpectedly high diversity of Trebouxia phycobionts within clade A across the Mediterranean Basin. Climatic niche modelling reveals that differences in photobiont climatic preferences contribute to symbiont switching and help explain the broad ecological amplitude and geographic success of this widespread lichen.

Mycosporine-like amino acids and phylogenies in green algae: Prasiola and its relatives from the Trebouxiophyceae (Chlorophyta)

, 2005
A UV-absorbing mycosporine-like amino acid (324 nm-MAA), so far only known from the green macroalgal genus Prasiola (Trebouxiophyceae), was also identified in other morphologically diverse green algae closely related to Prasiola spp.

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

New Phytologist, Volume 251, Issue 1, Page 372-383, July 2026.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

Phylogenomics reveals the evolutionary origins of lichenization in chlorophyte algae

Nature Communications
Mutualistic symbioses have contributed to major transitions in the evolution of life. Here, we investigate the evolutionary history and the molecular innovations at the origin of lichens, which are a symbiosis established between fungi and green algae or

Environmental and Spatial Processes Drive the Phylogenetic Diversity and Structure of Planktonic Microeukaryotes Revealed by 18S rDNA Metabarcoding in a Tropical Floodplain

Environmental DNA, Volume 8, Issue 3, May–June 2026.
The community structure of photosynthetic planktonic microeukaryotes in the floodplain lakes of the Tocantins‐Araguaia River basin is influenced by a combination of environmental filters and spatial processes. Phylogenetic information from this community highlights the importance of conserving less degraded areas to preserve the evolutionary diversity ...

Polyols and UV-sunscreens in thePrasiola-clade (Trebouxiophyceae, Chlorophyta) as metabolites for stress response and chemotaxonomy

, 2018
In many regions of the world, aeroterrestrial green algae of the Trebouxiophyceae (Chlorophyta) represent very abundant soil microorganisms, and hence their taxonomy is crucial to investigate their physiological performance and ecological importance. Due
