    New specimens of Taeniogyrus japonicus (Marenzeller) were collected from Iwami coast and Sado island of the Sea of Japan. According to detailed observations of external and internal organs, we transferred T. japonicus, T. dendyi (Mortensen), and Scoliorhapis theelii (Heding) to the newly revived genus Scoliodota, with a large retractor organ and hook papillae as major diagnostic characters. We also concluded that Scoliorhapis dianthus Solis-marin et al. is a synonym of T. japonicus. Our molecular phylogeny and genetic distance analysis showed that specimens from Iwami and specimens from Sado of T. japonicus form a monophyletic clade, indicating that they are most likely the same species despite their morphological variation. The phylogenetic analysis also indicated that T. japonicus forms a sister group relationship with Taeniogyrus verruculosus Yamana Tanaka and Scoliorhapis sesokoensis Yamana Tanaka, suggesting that Taeniogyrus is not monophyletic. Taken together, these results brought new insights to sea cucumber diversity in Japanese waters.

  • Derivedness Index for Estimating Degree of Phenotypic Evolution of Embryos: A Study of Comparative Transcriptomic Analyses of Chordates and Echinoderms Reviewed International journal

    Species retaining ancestral features, such as species called living fossils, are often regarded as less derived than their sister groups, but such discussions are usually based on qualitative enumeration of conserved traits. This approach creates a major barrier, especially when quantifying the degree of phenotypic evolution or degree of derivedness, since it focuses only on commonly shared traits, and newly acquired or lost traits are often overlooked. To provide a potential solution to this problem, especially for inter-species comparison of gene expression profiles, we propose a new method named “derivedness index” to quantify the degree of derivedness. In contrast to the conservation-based approach, which deals with expressions of commonly shared genes among species being compared, the derivedness index also considers those that were potentially lost or duplicated during evolution. By applying our method, we found that the gene expression profiles of penta-radial phases in echinoderm tended to be more highly derived than those of the bilateral phase. However, our results suggest that echinoderms may not have experienced much larger modifications to their developmental systems than chordates, at least at the transcriptomic level. In vertebrates, we found that the mid-embryonic and organogenesis stages were generally less derived than the earlier or later stages, indicating that the conserved phylotypic period is also less derived. We also found genes that potentially explain less derivedness, such as Hox genes. Finally, we highlight technical concerns that may influence the measured transcriptomic derivedness, such as read depth and library preparation protocols, for further improvement of our method through future studies. We anticipate that this index will serve as a quantitative guide in the search for constrained developmental phases or processes.

    After publication of Nakano et al. (2017) [1], the authors became aware of the fact that the new species-group name erected for the two specimens of a Japanese xenoturbellid species in the article is not available because Nakano et al. (2017) [1] does not meet the requirement of the amendment of Article 8.5.3 of the International Code of Zoological Nomenclature (the Code) [2]. The authors therefore describe the two xenoturbellids as a new species again in this correction article. Methods for morphological observation, DNA extraction and sequencing were as described in Nakano et al. (2017) [1]. The holotype and paratype specimens are deposited in the National Museum of Nature and Science, Tsukuba (NSMT), Japan. The DNA sequences obtained were deposited in the International Nucleotide Sequence Database (INSD).

    本研究では、概潮汐時計の機能的分子基盤の解明を目指して、潮汐サイクルおよび月齢に同調して発現する遺伝子群を網羅的に探索すると共に、それらの遺伝子の発現抑制による半月周性の産卵行動リズムへの影響を検討する。また、概潮汐時計と概日時計から構成されると考えられるリズム発振機構による生殖神経内分泌系の周期的調節の機能形態学的基盤を解明する。さらに、より普遍的な生物リズムの研究としての展開を目指し、半月周性リズムのOntogenyを解明する。令和3年度は、次の3つの研究成果を得た。
    1）潮汐サイクルと半月周性リズムに関連する遺伝子群を探索する試料として、産卵リズムの異なる伊豆川奈と佐渡姫津において、大潮と小潮の日の夕刻にクサフグ成魚を捕獲して脳を採取した。
    2）潮汐サイクル/半月周性リズムを作る時計候補遺伝子の機能解析のため、Vivo-モルフォリノによる遺伝子発現抑制実験系を検討した。脳髄膜で作られる糖たんぱく質であるエペンジミン（EPN）を標的遺伝子として、Vivo-モルフォリノ(EPN-MO)の配列、投与量、投与方法を検討した。また、ウェスタンブロット法と免疫染色法を用いたEPNタンパク質の解析系を確立した。EPN-MOを投与した個体では、遊泳阻害が見られたが、EPNタンパク質量の変化は検出されなかった。
    3）クサフグ仔稚魚に潮汐サイクルや月齢に同調したリズムがあるのかどうかを明らかにするため、産卵期に親魚を採集して人工授精を行い、仔稚魚を育成した。DanioVisionを用いて、クサフグ仔稚魚の自発行動リズムを解析した結果、成長段階によって明暗周期に関して自発行動リズムが異なることや明暗の切り替え時に自発行動量が高くなることなど、クサフグが独自の光応答性を持つ可能性が示された。さらに、EthoVision XTを用いたクサフグ幼魚の自発行動解析系を確立した。
