Summary: Nearly every animal species contains a unique polyketide synthase (PKS) encoded in its genome, but their biochemical characteristics and chemical products are still largely unknown. The PKS gene SpPks1 from sea urchins was the first one to be identified. Through biochemical experiments, it was found that SpPks1 is responsible for the synthesis of the precursor to echinochrome. This discovery redefines the biosynthetic pathway to echinoderm pigments.

Summary: Multinucleated cells or syncytia are common in various taxa, and their biological function is related to the compartmentalization of biochemical or cellular activities. This study reveals that transcription factors and biomineralization proteins have restricted mobility within the syncytium of sea urchin embryonic skeleton, and identifies motifs that limit their mobility.

Summary: The painted urchin Lytechinus pictus has become a tractable model system for establishing transgenic sea urchin lines due to its amenability to long term laboratory culture. The first published genome of L. pictus exhibits high contiguity and will serve as a key resource for comparative functional genomics.

Summary: Thyroid hormones have diverse physiological and developmental functions in animals and can activate both genomic and non-genomic signaling pathways. In sea urchin development, thyroid hormones regulate gene expression through both genomic and non-genomic mechanisms, with genomic signaling being more prominent during later stages of larval development.

Summary: In this study, a high-quality genome assembly of Echinometra lucunter was successfully achieved, with 21 scaffolds predicted to represent each of the species' chromosomes. This genome assembly represents a valuable resource for future evolutionary and developmental studies of this species and other echinoderms.

Summary: This study provides a comprehensive description of the development of the sea urchin species Paracentrotus lividus, including details on embryonic, larval, and juvenile stages. It is an important resource for researchers in the fields of ecotoxicology, developmental biology, and evolutionary studies, as well as those interested in using marine invertebrates as alternative model systems for biomedical investigations.

Summary: Echinoderm embryos, particularly sea urchin embryos, have been widely used as model systems in cell and developmental biology due to their optical clarity. Live imaging techniques, coupled with fluorescence microscopy, have played a pivotal role in uncovering mechanisms of embryonic development. This study argues for the adaptation of live imaging techniques to more echinoderm species in order to explore the evolutionary aspects of morphogenesis and understand the differences in dynamic cellular behaviors between species.

Summary: This study found that the new IMTA system can enhance the growth and behavior performances of Apostichopus japonicus and Strongylocentrotus intermedius, and reduce mortality and morbidity. Therefore, the IMTA system has the potential to improve the production efficiency of these two species in China.

Summary: This study presents a chromosome-level genome assembly for Echinometra sp. EZ, a sea urchin species from the Persian/Arabian Gulf, based on 10x Genomics, PacBio, and Hi-C sequencing. The assembly provides insights into the genome composition, gene content, and genetic factors associated with environmental stress response. The findings contribute to understanding the biology of E. sp. EZ and the diversification of the Echinometra genus, and also serve as a valuable resource for future research in this taxonomic group and beyond.

Summary: The global demand for sea urchin as seafood is currently unmet. This study examines the market potential of the unexploited Arbacia punctulata, and finds that manipulating the diet can increase gonad mass and alter color. Further research on the market potential of A. punctulata is warranted.

Summary: In 1983-1984, a waterborne pathogen caused mass mortality of long-spined sea urchins in the Caribbean and western tropical Atlantic. While some populations have started to recover, they have not reached pre-mortality densities. There is no documented evidence of recovery in the western tropical Atlantic outside of the Caribbean.

Summary: The aim of this study is to develop artificial feeds for the post-larvae of Paracentrotus lividus in order to improve production skills. Various natural and prepared components were tested, and a feed composed of spirulina and Ulva rigida was found to be the most effective. Statistical analyses showed that this diet had a positive impact on the growth, behavior, and survival rates of post-larvae. In addition, the efficacy of prepared feeds in the sea urchin aquaculture system was demonstrated, as they facilitated manipulation and control of the culture procedures for the satisfactory growth of P. lividus post-larvae.

Summary: The study explored the gene expression patterns and regulatory mechanisms of adult skeletogenesis in the starfish, revealing the activation of skeletogenic regulatory genes through the feeding-nutrient sensing pathway and Vegf signaling. Compared to sea urchins, the skeletogenesis of starfish may involve changes in the upstream regulatory system, resulting in alterations to the skeletal development mechanism.
