Marine Tubeworm Metamorphosis Induced by Arrays of Bacterial Phage Tail–Like Structures
Open accessAbstract
Big MACs: Tubeworms are important marine benthic species that encrust rocks and contribute to fouling of man-made objects, such as ships' hulls and drilling well heads. Like most marine invertebrates, the larval stages of tubeworms are free-swimming, but the cues for larval settlement and the triggers for metamorphosis are mysterious. Shikuma et al. (p. 529 , published online 9 January) experimented on larval settlement by the tubeworm, Hydroides elegans , which needs to associate with a biofilm-forming bacterium, Pseudoalteromonas luteoviolacea , before settlement can occur. The bacterium was found to express metamorphosis-associated contractile structures (MACs) in large and structurally elaborate arrays that allow the tubeworm larvae to develop.

In many marine organisms, metamorphosis is triggered by environmental cues indicating a suitable settlement site for a planktonic larval stage.

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.
