“…In addition, chromosomes within this genus are extremely small. Accordingly, to confirm the allopolyploidy from the previous study, the gametophytic blades that were developed from archeospores were examined by multiple nuclear markers (Niwa et al, , 2018(Niwa et al, , 2020.…”

To confirm the distribution of the allopolyploid and ancestral species in the Matsukawaura Lagoon in a hybrid zone between Neopyropia yezoensis and Neopyropia tenera, molecular marker analyses and culture experiments were performed using collected blades. All the blades examined, except for one blade identified as N. tenera, exhibited nuclear genotypes of both species, but only the chloroplast haplotype of N. yezoensis. In addition, four conchocelis strains were isolated from each of the blades, and they contained genotypes of both N. yezoensis and N. tenera; a conchocelis strain from the sole N. tenera blade was also isolated. Using the conchocelis strains, F 1 blades that were produced from archeospores were obtained under laboratory culture and examined by nuclear DNA markers. These results indicated that the collected blades and the examined F 1 blades, except for the single N. tenera blade, were allodiploids and that the four conchocelis strains could be allotetraploids derived from interspecific hybridization between N. yezoensis as the maternal strain and N. tenera as the paternal strain. Therefore, most of the Neopyropia blades growing in the Matsukawaura Lagoon are presumed to be from allopolyploid lineages derived from interspecific hybridization. Furthermore, a growth comparison between the allopolyploid strain and the N. tenera strain was carried out under identical culture conditions. The rate of increase in blade length was significantly higher in the allopolyploid hybrid than in the pure N. tenera. The results suggest that further exploration of allopolyploidy in the potential hybrid zones will be needed not only for the investigation of speciation mechanisms in the bladed Bangiales but also for the genetic improvement of the marine crop.

“…Japan also has a "National Seaweed Day" (February 6), which was established in 1966 by the National Lionfish and Shellfish Cooperative Federation Association in accordance with a consensus of Japanese seaweed fishermen. This date marks the beginning of the nori season (early spring); nori (purple laver in English) is a dry edible seaweed used in Japanese cuisine (red algae of the genus Pyropia including P. yezonesis and P. tenera) [365].…”

Macroalgae are invaluable constituents of marine forest environments and important sources of material for human needs. However, they are currently at risk of severe decline due to global warming and negative anthropogenic factors. Restoration efforts focus on beds where macroalgae previously existed, as well as the creation of new marine forests. Some artificial seaweed reefs (ASRs) have succeeded but others have failed; the contributions of ASRs to marine forest formation have been not fully determined. Here, we review ASRs, the benefits of macroalgal forests, threats to macroalgae, restoration, and marine forest formation to explore the current status of ASRs. The published literature indicates that ASRs have played critical roles in marine forest formation; notably, they support the establishment of submerged aquatic vegetation beds that allow ocean macroalgal afforestation. ASRs have evolved in terms of complexity and the materials used; they can sustainably mitigate marine deforestation. However, continuous reviews of ASR performance are essential, and performance improvements are always possible.
