Summary: This study shows that sea anemones acclimated to high temperatures demonstrate increased resistance to thermal stress and that this improved adaptation can be transferred through microbiome transplantation. The findings suggest that microbiome plasticity may play a crucial role in thermal adaptations in animals.

Summary: In cnidarians like Nematostella vectensis, long-term ecological success relies on sexual reproduction, with temperature and light being major inducers for spawning. Transcriptome analysis revealed upregulation of various processes like receptors and cytoskeleton during spawning induction, while downregulation of cell cycle and metabolism-related processes was observed. Our findings also suggest temperature change as a stronger inducer for spawning in Nematostella, expanding our understanding of sexual reproduction in cnidarians.

Summary: Most multicellular organisms have microbial colonizers that provide benefits to the hosts. This study examines the relative contribution of environment and host genotype to bacterial community composition in Nematostella vectensis, a marine organism. The results show that bacterial communities in N. vectensis respond to changes in ambient temperature and are influenced by host genotype. This study highlights the importance of understanding the plasticity of microbial communities in response to environmental changes.

Summary: We investigate factors influencing asexual reproduction in Nematostella vectensis, a burrowing sea anemone capable of transverse fission. Our study demonstrates that the presence of a burrowing substrate strongly promotes transverse fission and animal size does not affect fission rates. Gene expression analysis suggests that transcription factors and signaling pathways play vital roles in regulating transverse fission. Additionally, we find that the cell cycle is suppressed and cell adhesion and patterning mechanisms are downregulated during fission. This research provides insights into the reproductive biology of cnidarians.

Summary: This study reveals the developmental mechanism of a truly novel cell type, cnidocytes. Cnidocytes develop by suppressing the neural fate of a subset of neurons expressing RFamide. A single regulatory gene, a C2H2-type zinc finger transcription factor (ZNF845), plays a crucial role in the development of cnidocytes and emerged through domain shuffling in the ancestor of cnidarians.

Summary: Using the sea anemone Nematostella vectensis as a model system, researchers found that neurons and secretory cells derive from a common pool of progenitor cells, with NvInsm1 playing a crucial role in this process, revealing a close evolutionary relationship between neurons and secretory cells.

Summary: Parental exposure to elevated temperatures can increase larval thermal tolerance in Nematostella vectensis, with subsequent spawns returning to baseline thresholds when parents are back to normal temperatures, indicating plasticity in parental effects. Maternal effects in gametogenesis may play a role in facilitating dynamic shifts in larval thermal tolerance. Despite genetic differences, parental populations from different locations can increase larval thermal tolerance under high-temperature conditions, suggesting that plasticity in parental effects is inherent in N. vectensis.

Summary: Sampling of different body regions can reveal highly specialized bacterial associations within the holobiont and facilitate identification of core microbial symbionts that would otherwise be overlooked by bulk sampling methods. Through compartment-specific sampling of the model cnidarian Nematostella vectensis, a dominance of spirochetes in the capitulum was uncovered, with a phylogenetic analysis showing a close relation to spirochetes previously recovered from wild N. vectensis, suggesting a prevalent and yet uncharacterized association between N. vectensis and spirochetes from the order Spirochaetales.

Summary: Nematostella, with its unique features of whole-body regeneration, absence of aging signs, and lack of age-related diseases, is a promising research model in regenerative medicine, longevity, and mecano-sensory diseases. It provides new opportunities for scientists to explore these fields in an integrative manner as a complementary model to vertebrates.
