Development in the sea is tough and can end in starvation. @tylerjcarrier.bsky.social @utehentschel.bsky.social &co show that #SeaUrchin eggs contain a #plastid -derived structure whose light-dependent activity influences metabolism, #development & survival @plosbiology.org 🧪 plos.io/4mOAxZh

Top: Micrographs of unfertilized eggs from the sea urchin Arbacia lixula without (top panels) and with (bottom panels) cytoplasmic autofluorescent particles. These particles were most consistent for the presence of carotenoids, as shown using (left) transmitted light and (right) fluorescence at an excitation of 561 nm. The light micrograph is a single optical slice, while the florescence micrograph is a maximum projection Z-stack. Bottom: These autofluorescent structures correspond with large crystals (CC) observed in transmission electron micrographs. Mitochondria (Mt) and yolk platelets (YP) are also noted. The combined fluorescence signature and cellular structure implies that these crystal structures are chromoplast-derived carotenoid crystals.

Eggs released in the environment are at risk from many threats. @jillianlewis.bsky.social & @spencernyholm.bsky.social explore how #plastid -derived #carotenoid crystals benefit larval survival & trans-oceanic dispersal in #SeaUrchin eggs 🧪 Paper: plos.io/4mOAxZh Primer: plos.io/4cPpBGr

Transmission and benefits of plastid-derived structures in sea urchin eggs. Top: Proposed mechanism of transmission of plastid-derived structures. From left to right: Adult female sea urchin ingests diatoms and releases eggs that contain carotenoid-like crystals. These carotenoid crystals may be enzymatically cleaved into apocarotenoids (i.e., phytohormones). Bottom left: Eggs of Arbacia lixula reared in light (receiving benefits from carotenoids) had higher hatching and survival rates, increased fatty acid metabolism, and an enrichment of apocarotenoids compared to those reared in the dark. Bottom right: Larvae receiving benefits from carotenoids were modeled to disperse along the African shelf in fewer generations and predicted to survive trans-oceanic dispersal.

Tyler J. Carrier @tylerjcarrier.bsky.social · 23/04/2026

We hypothesize that this process—preliminarily termed ‘machiaplasty’ for the Machiavellian traits of manipulation, indifference, and self-interest—involves three stages: (1) chloroplast isolation during grazing, (2) differentiation into chromoplast, and (3) incorporation into the egg.

Tyler J. Carrier @tylerjcarrier.bsky.social · 23/04/2026

These data provide initial evidence to challenge the long-held belief that components of non-metazoan organelles are unable to cross the evolutionary valley between non-reproductive (somatic) and reproductive (germline) cells.

Tyler J. Carrier @tylerjcarrier.bsky.social · 23/04/2026

Moreover, only larvae that benefit from the light-dependent activity of these chromoplast components were predicted to undergo trans-Atlantic dispersal via the South Equatorial Current.

110

Tyler J. Carrier @tylerjcarrier.bsky.social · 23/04/2026

Using a full-scale oceanographic model of the Atlantic Ocean, we estimate that this difference in dispersal potential translates to ~3x more larvae the ability to disperse 1.6x further and across a 4.7x larger area.

110

Tyler J. Carrier @tylerjcarrier.bsky.social · 23/04/2026

Development and survival can directly impact dispersal. We estimate that offspring that benefit from the light-dependent activity of chromoplast components have a 1.8x longer dispersal duration than those without it.
