vectensis, while others may play a role in regulating proliferation during regeneration. ASM20922v1 Organism: Nematostella vectensis (starlet sea anemone) Submitter: DOE Joint Genome Institute (JGI) Date: 2 Assembly type: Assembly level: Scaffold Genome representation: full RefSeq category: representative genome GenBank assembly accession: GCA000209225.1 (latest) RefSeq assembly accession: GCF000209225. The integrins expressed in the gonads may play roles in mediating sperm-egg interactions in N. The starlet sea anemone has a bulbous basal end and a contracting column (usually less than two cm but no more than six cm) in order to burrow into the mud. Our observations confirm that complex patterns of integrin expression were already present in basal metazoans. One of the β subunits is expressed 8-fold higher during regeneration, and its expression is observed in cells within both the epidermis and the gastrodermis at the site of regeneration. Research suggests it’s originally native to the east coast of North America. Nematostella vectensis (Starlet Sea Anemone) is a species of cnidarians in the family Edwardsiidae. Changes in expression were also studied 48 h after horizontal transection by quantitative reverse transcription PCR and in situ hybridization. The starlet sea anemone, or Nematostella vectensis, lives burrowed into the mud and silt of coastal salt marshes. The three β subunits each have distinctive patterns of expression: one is concentrated in the gonad and mesenteric filament, another is found in a subset of cells in the epidermis of the oral region and in a subset of gastrodermal cells in the mesenteries, and a third is expressed widely. The α subunit is primarily expressed in cells near muscles, by a subset of gastrodermal cells, and in the gonad. Induction of spawning in the starlet sea anemone Nematostella vectensis, in vitro fertilization of gametes, and dejellying of zygotes Cold Spring Harb Protoc. The expression of one of the α subunits and three of the β subunits was confirmed by reverse transcription PCR and in situ hybridization. The β subunits cluster with the previously described β integrins of the hard coral Acropora millepora. Background Although much is known about how circadian systems control daily cycles in the physiology and behavior of Drosophila and several vertebrate models, marine invertebrates have often been overlooked in circadian rhythms research. Phylogenetic analysis suggests that the α subunits are most closely related to RGD- and LDV-dependent α subunits of chordates. Here we describe two α subunits and four β subunits from the starlet sea anemone Nematostella vectensis. Integrins are extracellular matrix receptors composed of α and β subunits.
