    Regeneration is a widely observed phenomenon by which the integrity of an organism is recovered after damage. To date, studies on the molecular and cellular mechanisms of regeneration have been limited to a handful of model multicellular organisms. Here, the regeneration ability of marine macroalgae (Rhodophyta, Phaeophyceae, Chlorophyta) was systematically surveyed after thallus severing. Live cell imaging on severed thalli uncovered the cellular response to the damage. Three types of responses–budding, rhizoid formation, and/or sporulation–were observed in 25 species among 66 examined, proving the high potential of regeneration of macroalgae. The cellular and nuclear dynamics were monitored during cell repair or rhizoid formation of four phylogenetically diverged species, and the tip growth of the cells near the damaged site was observed as a common response. Nuclear translocation followed tip growth, enabling overall distribution of multinuclei or central positioning of the mononucleus. In contrast, the control of cell cycle events, such as nuclear division and septation, varied in these species. These observations showed that marine macroalgae utilise a variety of regeneration pathways, with some common features. This study also provides a novel methodology of live cell imaging in macroalgae.

    We report two red algal species, Chondracanthus saundersii C.W. Schneider & C.E. Lane (Gigartinaceae, Gigartinales) and Schottera koreana M.S. Calderon, T.H. Seo & S.M. Boo (Phyllophoraceae, Gigartinales), from Japan for the first time based on molecular and morphological analyses. A C. saundersii specimen was collected at a depth of 35 m offshore of Mageshima Island, Kagoshima Prefecture, Japan. The rbcL and COI-5P (cox1) sequences of C. saundersii form a clade with the type specimen from Bermuda and additional specimens from Cuba and Brazil. Morphologically, C. saundersii is characterized by the presence of secondary attachments, compressed to flattened axes up to 1 mm in width, and a looser medulla. Two specimens of S. koreana were collected in lower intertidal to subtidal waters at Ohara, Chiba Prefecture, and Matsuyama, Ehime Prefecture, Japan. The rbcL sequences of S. koreana were closely related to reported sequences of specimens from South Korea including the type specimens. Morphologically, S. koreana is characterized by the presence of unicellular colorless hair developed from cortical cells.

    We collected the deep-water species Rhodymenia prostrata (Rhodymeniaceae, Rhodophyta), for the first time in nearly 50 years, from the type locality off Mageshima Island, Japan. Our combined rbcL, cox1 and 28S rDNA analyses suggested that R. prostrata belongs in the genus Halopeltis but is distinct from all other Halopeltis species. However, the binomial Halopeltis prostrata already exists and hence a new epithet was required. Consequently, we propose the new name Halopeltis tanakae for R. prostrata based on morpho-anatomical and molecular analyses. The occurrence of small intercalating cells in H. tanakae is congruent with the generic concept of Halopeltis. Halopeltis tanakae is characterized by a procumbent thallus, crispate blades, cystocarps lacking basal constrictions, cystocarps primarily on blade margins, and mucilaginous strands in cystocarp cavities. Halopeltis tanakae is the second representative of the genus to be reported from the northwestern Pacific.

    A new flattened species of Gracilariopsis from Mageshima Island, Japan is recognized based on morphological and molecular analyses of rbcL and cox1 DNA sequences. We name this new species Gp. mageshimensis sp. nov. The rbcL and cox1 analyses suggest that Gp. mageshimensis belongs to the Gracilariopsis clade, and that it is distinct from other Gracilariopsis species. Gracilariopsis mageshimensis is characterized by a flattened thallus, the lack of tubular nutritive cells, the lower gonimoblasts connect to the cystocarp floor cells via pit connections and small gonimoblasts filling the cystocarp cavity. The Gp. mageshimensis cystocarp is in accordance with the morphological concept of Gracilariopsis. Gracilariopsis mageshimensis is the second Gracilariopsis species with a flattened thallus to be described worldwide. Gracilariopsis mageshimensis is distinguished from Gp. silvana, the first flattened species by the rare production of lateral branches, a medulla consisting of fewer than five layers, and its deep-water habitat.
