Maternal transmission of a plastid structure enhances offspring fitness

2025-10-22

Abstract excerpt

<h4>ABSTRACT</h4> Development in the sea has long been thought to be a nutritional gamble that disproportionately ends in starvation. Here, we unexpectedly show that components of plastids are incorporated into sea urchin eggs and that these, in turn, benefit developmental fitness. We find chromoplast-derived carotenoid crystals and chromoplast-specific metabolites inside of sea urchin eggs. The light-dependent a...
