Seasonal and taxa impact on edible sea cucumber's metabolome and in relation to its cytotoxicity as analyzed via UHPLC/HR‐MS/MS‐based molecular networking and chemometrics

Food Frontiers, Volume 5, Issue 2, Page 584-606, March 2024.
Abstract Sea cucumbers, belonging to class Holothuroidea, are marine invertebrates with substantial bioactive compounds. This study provides the first comparative metabolome profiling of Holothuria atra and Actinopyga crassa sea cucumbers in relation to their season of collection to dissect between winter and summer samples, providing several first ...

Differences in the percent cover of lipids and plastids based on area in TEMs of animals exhibiting transient and permanent kleptoplasty.

, 2014
(A) Percent cover (mean ± SD) of lipids and plastids from micrographs (n = 3) of animals fed 5 d (transient kleptoplasty) and then starved for 1 or 7 d (grey bars) compared to same age control animals fed continuously (green bars).

Strombidium rassoulzadegani: A Model Species for Chloroplast Retention in Oligotrich Ciliates

Frontiers in Marine Science, 2018
Strombidium rassoulzadegani is a planktonic ciliate that retains chloroplasts from its food and uses them to obtain a nutritional supplement from photosynthesis.

Photoprotective mechanisms in Elysia species hosting Acetabularia chloroplasts shed light on host‐donor compatibility in photosynthetic sea slugs

Physiologia Plantarum, Volume 176, Issue 2, March/April 2024.
Abstract Sacoglossa sea slugs have garnered attention due to their ability to retain intracellular functional chloroplasts from algae, while degrading other algal cell components. While protective mechanisms that limit oxidative damage under excessive light are well documented in plants and algae, the photoprotective strategies employed by these ...

Chemical defenses in Sacoglossan Opisthobranchs: Taxonomic trends and evolutionary implications

Scientia Marina, 2004
Sacoglossan sea slugs (Mollusca: Opisthobranchia) are one of the few groups of specialist herbivores in the marine environment. Sacoglossans feed suctorially on the cell sap of macroalgae, from which they "steal" chloroplasts (kleptoplasty) and deterrent

Mucopolysaccharides secreted by the sea slug Elysia crispata incorporate carbon via kleptoplast photosynthesis

Frontiers in Marine Science
Some Sacoglossa sea slugs feed on macroalgae and sequester chloroplasts in the cells of their digestive diverticulum. In some species, mostly within the genus Elysia, the stolen chloroplasts – kleptoplasts – remain photosynthetically competent for weeks ...

Why mixotrophy flourished in water but rarely on land

Frontiers in Ecology and Evolution
Mixotrophy, the ability to combine photosynthesis with heterotrophic acquisition of carbon or nutrients, is now recognized as a central feature of aquatic microbial food webs and a recurrent strategy in several protist and simple animal lineages.

Preservation and remodelling of chloroplast lipids in photosynthetic sea slug host cells

Frontiers in Marine Science
The capacity to retain long-term functional algal chloroplasts within animal cells is a singular trait of certain Sacoglossa sea slugs. The sequestered chloroplasts (kleptoplasts) confer photosynthetic capacity to the host.

Underestimated genomic footprint of kleptoplasty in complex algae evolution? [PDF]

Complex algae form a network of photosynthetic organisms scattered across the eukaryotic tree. However, the exact mechanisms by which their plastids were acquired remain unclear.

Complete mitochondrial genome of Polybranchia orientalis sp. nov. from the South China Sea

Frontiers in Marine Science
A species of sea slug discovered in the South China Sea was characterized based on its morphology, mitochondrial genome, and phylogenetic position. The slug exhibits brown coloration, resembling seaweed.
