Microbiota mediated plasticity promotes thermal adaptation in the sea anemone Nematostella vectensis

Nature Communications, 2022
At the current rate of climate change, it is unlikely that multicellular organisms will be able to adapt to changing environmental conditions through genetic recombination and natural selection alone.

Single-cell atavism reveals an ancient mechanism of cell type diversification in a sea anemone

Nature Communications, 2023
Understanding how new cell types arise is essential for understanding the evolution of animal diversity. This study shows that a single gene, NvSox2, acts as a simple switch controlling the development of two alternative types of stinging cells in the ...

Spatial gene expression quantification: a tool for analysis of in situ hybridizations in sea anemone Nematostella vectensis

BMC Research Notes, 2012
Background Spatial gene expression quantification is required for modeling gene regulation in developing organisms. The fruit fly Drosophila melanogaster is the model system most widely applied for spatial gene expression analysis due to its unique ...

Regulation of AP-1 by MAPK Signaling in Metal-Stressed Sea Anemone

Cellular Physiology and Biochemistry, 2017
Background/Aims: AP-1 transcription factor plays a conserved role in the immediate response to stress. Activation of AP-1 members jun and fos is mediated by complex signaling cascades to control cell proliferation and survival.

Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

eLife, 2020
Two distinct mechanisms for primordial germ cell (PGC) specification are observed within Bilatera: early determination by maternal factors or late induction by zygotic cues. Here we investigate the molecular basis for PGC specification in Nematostella, a

Updated single cell reference atlas for the starlet anemone Nematostella vectensis

Frontiers in Zoology
The recent combination of genomics and single cell transcriptomics has allowed to assess a variety of non-conventional model organisms in much more depth.

Starvation decreases immunity and immune regulatory factor NF-κB in the starlet sea anemone Nematostella vectensis

Communications Biology, 2023
Lack of proper nutrition has important consequences for the physiology of all organisms, and nutritional status can affect immunity, based on many studies in terrestrial animals.

Molecular characterization of the apical organ of the anthozoan Nematostella vectensis

Developmental Biology, 2015
Apical organs are sensory structures present in many marine invertebrate larvae where they are considered to be involved in their settlement, metamorphosis and locomotion. In bilaterians they are characterised by a tuft of long cilia and receptor cells and they are associated with groups of neurons, but their relatively low morphological complexity and

Nanos2 marks precursors of somatic lineages and is required for germline formation in the sea anemone Nematostella vectensis

Science Advances
In animals, stem cell populations of varying potency facilitate regeneration and tissue homeostasis. Notably, germline stem cells in both vertebrates and invertebrates express highly conserved RNA binding proteins, such as nanos, vasa, and piwi.

Conserved and lineage-restricted gene regulatory programs modulate developmental cnidocyte specification in Nematostella vectensis

bioRxiv
Cnidocytes are a synapomorphy of cnidarians that have evolved a range of morphologies and functions within and across extant species, which makes them an excellent model to investigate how novel cell types emerge and radiate in evolution. One way to gain
