The cercozoan parasitoid Pseudopirsonia infects marine diatoms. Currently, only one species, P. mucosa, in the genus has been formally described in the North Sea. In June 2022 and 2023, we found that the diatom Chaetoceros constrictus was infected by a novel cerco...
The monospecific Symbiochlorum genus (Ulvophyceae) was recently described and found to be associated with bleached corals in the South China Sea. A new microchlorophyte strain was isolated from the hydrocoral Millepora alcicornis collected in a reef system in the S...
Many species of the dinoflagellate genus Karenia produce neurotoxins and often cause harmful algal blooms. Heterotrophic dinoflagellates are major grazers of bloom-forming dinoflagellates. Therefore, to understand the population dynamics of Karenia species, it is n...
During August 2022, a persistent harmful algal bloom (HAB) caused by the dinoflagellate Margalefidinium polykrikoides (aka Cochlodinium polykrikoides) occurred in the coastal waters of Yeosu, South Korea. This study aimed to char acterize the bloom by comparing pla...
The interplay between calcium signaling and reactive oxygen species (ROS) production is important in many cellular activities, yet its involvement in biological processes in red algae is mostly not studied. Fertilization in red algae is unique, and while it is known that ROS is ...
Diatoms are photosynthetic unicellular organisms surrounded by silica-based cell walls known as frustules. Given their widespread distribution in aquatic systems and their prolific nature, diatoms play a pivotal role in global silica cycling. Silicon transporter (SIT) proteins p...
Shell infiltration of free-living conchocelis of the three commercial Pyropia species (P. yezoensis, P. seriata, and P. dentata) were examined in various conditions of temperatures (20–25°C), light intensities (1, 10, 40, and 80 μmol photons m...
Seaweed farming is emerging as a scalable and effective carbon dioxide removal (CDR) strategy, offering direct sequestration benefits through carbon uptake pathways and indirect climate advantages by substituting carbon-intensive products. This paper evaluates the potential of s...
