Induction of gametogenesis in the basal cnidarian Nematostella vectensis (Anthozoa)

Fritzenwanker, Jens H., Technau, Ulrich·2002·Development Genes and Evolution

Abstract

A protocol was established to reproducibly induce spawning in the basal cnidarian Nematostella vectensis (Anthozoa). We found that a combination of feeding regime, dark-light cycle and temperature shift synergistically induced gametogenesis in adult polyps. Females lay between 100-600 eggs. This procedure led reproducibly to the production of thousands of eggs over the course of more than 1 year in weekly cycles. Gametes are released in a time window of about 2 h resulting in predictable and fairly synchronized development. We also present a method for in vitro fertilization allowing manipulation of early embryos. These methods as well as the simple culture conditions could provide important prerequisites for the use of Nematostella as a model system for the development of a basal Metazoa.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Representatives of all reported superfamilies and groups of eukaryotic DNA transposons, excluding the Transib superfamily and the Mariner group of the Mariner superfamily, are present in the anemone genome.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
