Open AccessMolecular phylogeny and genetic diversity of the economic seaweed Meristotheca (Gigartinales, Rhodophyta) in the northwest Pacific, with a description of M. pilulaora sp. nov
Species of the red algal genus Meristotheca are important natural resources that can be used directly as food for human consumption as well as raw materials for the extraction of carrageenan. Despite being harves...

Verification of hotspots of genetic diversity in Korean population of Grateloupia asiatica and G. jejuensis (Rhodophyta) show low genetic diversity and similar geographic distribution
Understanding the genetic diversity and distribution patterns of seaweeds species is crucial for evaluating key regions of high genetic diversity. Identifying hotspots of high intraspecific diversity is an imp...

Genetic diversity and distribution pattern of economic seaweeds Pyropia yezoensis and Py. suborbiculata (Bangiales, Rhodophyta) in the northwest Pacific
Pyropia yezoensis and Py. suborbiculata have been traditionally important for marine aquaculture as food resources in the northwest Pacific region. We conducted molecular analyses using plastid rbcL and mitochond...

Genetic diversity hotspot of the amphi-Pacific macroalga Gloiopeltis furcata sensu lato (Gigartinales, Florideophyceae)
Genetic diversity patterns around the North Pacific received attention for marine organisms and have been used to infer biodiversity “hotspots” in the region. We conducted a phylogeographic study of the red alga

DNA barcoding reveals cryptic diversity of economic red algae, Pyropia (Bangiales, Rhodophyta): description of novel species from Korea
Red algal genus Pyropia that includes several commercially important species is distributed in wide regions of the world from cold temperate to tropical marine environments. Despite their practical utility, speci...

Article
DNA barcoding of the funoran-producing red algal genus Gloiopeltis (Gigartinales) and description of a new species, Gloiopeltis frutex sp. nov.
The funoran-producing red macroalga, Gloiopeltis, is known for its commercial uses. Since the economic value of Gloiopeltis is species-dependent, accurate species identification using molecular analysis such as D...

Open AccessMiuraea migitae, a new record of the order Bangiales (Bangiophyceae, Rhodophyta) from Korea
We found specimens of foliose Bangiales from the subtidal zone of Udo, Jeju Island, Korea. In molecular analyses of rbcL sequences, these Korean specimens were almost identical to Miuraea migitae from Osaka, Japa...

Dynamics of bacterial communities in rice field soils as affected by different long-term fertilization practices
Fertilization and the response of the soil microbial community to the process significantly affect crop yield and the environment. In this study, the seasonal variation in the bacterial communities in rice fie...

Article
Molecular analyses for identification of the Gracilariaceae (Rhodophyta) from the Asia–Pacific region
The family Gracilariaceae contains economically important seaweeds and is well known as a difficult group for the species identification due to its high species diversity and uncertainty of species limits. To ...

Article
Taxonomy of Grateloupia (Halymeniales, Rhodophyta) by DNA barcode marker analysis and a description of Pachymeniopsis volvita sp. nov.
We applied DNA barcoding analysis to the red alga Grateloupia because it is one of the most complicated taxa in the family Halymeniaceae. We used two DNA barcoding markers, the 5′ end of the cytochrome c oxidase ...

Open AccessDNA barcode assessment of Gracilaria salicornia (Gracilariaceae, Rhodophyta) from Southeast Asia
DNA barcoding is becoming a widely applied tool for the quick and accurate identification of species. The evolution of the mitochondrial cytochrome c oxidase subunit I (COI) gene is sufficiently rapid to allow di...

Article
Molecular identification of Grateloupia elliptica and G. lanceolata (Rhodophyta) inferred from plastid rbcL and mitochondrial COI genes sequence data
The marine red algae Grateloupia is the largest genus in the family Halymeniaceae and widely distributed from tropical to warm temperate regions of the world. In the genus Grateloupia, especially G. elliptica and...

Characterization of the bacterial and archaeal communities in rice field soils subjected to long-term fertilization practices
The bacterial and archaeal communities in rice field soils subjected to different fertilization regimes for 57 years were investigated in two different seasons, a non-planted, drained season (April) and a rice...

Mitochondrial cox1 and plastid rbcL genes of Gracilaria vermiculophylla (Gracilariaceae, Rhodophyta)
The mitochondrial cytochrome c oxidase subunit I gene sequence was recently developed for DNA barcoding of red algal species. We determined the 1245 base pairs of the gene from 27 taxa of an agar-producing spe...

A preliminary study of the bioremediation potential of Codium fragile applied to seaweed integrated multi-trophic aquaculture (IMTA) during the summer
In integrated multi-trophic aquaculture (IMTA), seaweeds have the capacity to reduce the environmental impact of nitrogen-rich effluents in coastal ecosystems. To establish such bioremediation systems, selecti...
