Examination of the nematostella vectensis holobiont by comparative bacterial genomics and metatranscriptomics
… are associated with the starlet sea anemone Nematostella vectensis over distinct temporal and geographic locations; however, the functions these bacteria may be performing within their anemone hosts and the mechanisms with which the bacteria may be using to adapt are unknown. To address these …

Understanding the evolution of the apical organ in the early branching metazoan, Nematostella vectensis
… in cnidarian larvae, with a particular focus on Nematostella vectensis. As an early-branching metazoan, N. vectensis is a unique model for studying evolution of the apical organ, and subsequently the origins of the nervous system. Through generating tissue-specific transcriptomes and integrating …

CRSPR manipulation and nutritional status reveal functions of transcription factor NF-kappaB in the sea anemone Nematostella vectensis
… signaling is characterized in the sea anemone Nematostella vectensis, a commonly used model in the phylum Cnidaria. By RNA-seq analysis, a positive correlation between nutrition and immunity is shown in Nematostella. Gene expression profiling of adult fed and starved anemones showed that …

Behind anemone lines: determining the environmental drivers influencing lagoonal benthic communities, with special reference to the anemone Nematostella vectensis.
… The non-native protected Starlet Sea Anemone Nematostella vectensis was also significantly negatively correlated with organic matter and silt content. It is known to be sensitive to hypoxic-sulfidic conditions associated with high organic matter sediments. The anemone’s indiscriminate and …

Introducing the starlet sea anemone Nematostella vectensis as a model for investigating microbial mediation of health and disease in hexacorals
… Cnidarian model, the starlet sea anemone Nematostella vectensis, to investigate whether hexacorals maintain communities of beneficial microbes. I hypothesize that loss of this beneficial community by environmental perturbations will negatively impact the physiology of the host. As a first …

Investigating the evolution and functionality of closely related Wnt ligands in Drosophila melanogaster
… covers all major animal divisions including: Nematostella vectensis, Platynereis dumerilli, Mus Musculus , Aides aegypti , Tribolium castaneum Bicyclus anynana , and Parasteatoda tepidariorum . This work indicated that insertion predicted in Drosophila Wnts appears to be unique and mostly …

Evolutionary conservation and characterization of the metazoan amino acid response
… and characterize the ISR in the basal metazoan, Nematostella vectensis, revealing that the core components of the mammalian ISR were present over 550 million years ago in the common ancestor of cnidarians and bilaterians. Additionally, our lab has discovered a novel branch of the AAR pathway that …

Genetic connectivity, adaptation, and phenotypic plasticity of corals and anemones under thermal stress
… short time scales, using the estuarine anemone Nematostella vectensis. Indeed, I find parents exposed to increased temperatures quickly produce more thermally tolerant larvae. In fact, offspring from these Massachusetts parents show thermal thresholds that are indistinguishable from more …

SENSITIVITY AND RESILIENCE OF CNIDARIAN EARLY LIFE PROCESSES TO ANTHROPOGENIC CLIMATE CHANGE
… in early life stages of the sea anemone Nematostella vectensis, demonstrating hormetic conditioning. We also found that exposure to seawater hypoxia disturbed aerobic metabolism leading to disrupted growth, development (e.g., decreased settlement), and physiology (e.g., decreased larval …

Exploring circadian rhythms, food intake, and their interactions in marine invertebrates
… regimes on circadian rhythms in the sea anemone Nematostella vectensis. Misaligned light and temperature cycles severely disrupt behavioral rhythms and substantially alter the rhythmic transcriptome, particularly the expression of genes mediating metabolic processes. This illustrates how …

Evolution of Sp Transcription Factors in Metazoans
… btd Orthologe schon in so basalen Metazoa wie Nematostella vectensis und Trichoplax adhearens vorhanden sind. Es hat sich gezeigt, dass ein Satz von drei Sp Genen anzestral in den Metazoa ist und der Ursprung von btd somit bis zum gemeinsamen Vorfahren der Metazoa zurückverfolgt werden kann. …

Phylogenomics of vertebrate serpins
… the phylogenetic relationships of serpins from Nematostella vectensis, Strongylocentrotus purpuratus, Ciona intestinalis, four fish species, frog, chicken and mammals were investigated, using gene architecture analyses and stringent criteria for identification of orthologs. With some deviations, …

Characterization of doublesex and nanos genes in Acropora millepora
… DNAs of nanos homologs of Acropora millepora and Nematostella vectensis. Cnidarians have two nanos homologs, cnnos1 and cnnos2. All Nanos proteins have the highly conserved Zinc finger domains. The phylogenetic analysis demonstrated that two cnnos genes segregated before the cnidarian radiation. …
