Temporal and spatial diversity and abundance of cryptophytes in San Diego coastal waters

Journal of Phycology, Volume 60, Issue 3, Page 668-684, June 2024.
Abstract Cryptophytes (class Cryptophyceae) are bi‐flagellated eukaryotic protists with mixed nutritional modes and cosmopolitan distribution in aquatic environments. Despite their ubiquitous presence, their molecular diversity is understudied in coastal waters.

Photoprotective Non-photochemical Quenching Does Not Prevent Kleptoplasts From Net Photoinactivation

Frontiers in Ecology and Evolution, 2018
The enigmatic association of photosynthetically active chloroplasts from algae and some sacoglossan sea slugs, called functional kleptoplasty, is a functional unique system of photosymbioses observed in metazoans.

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 ...

Identifying potential keystone microbes from co-occurrence networks in the Gulf of Alaska

Frontiers in Marine Science
The Northern Gulf of Alaska (NGA) is a highly productive and diverse marine ecosystem. Differences in nutrient supply and physical circulation between nearshore and offshore waters in the NGA result in a mosaic of water masses with distinct ...

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 ...

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.

Preliminary Study of Kleptoplasty in Foraminifera of South Carolina [PDF]

, 2014
Recent studies of living foraminifera, microscopic aquatic protists, indicate that some species have the ability to steal photosynthetic plastids from other microorganism and keep them viable through a process called kleptoplasty.

Fotofisiologia de macroalgas potencialmente dadoras de cloroplastos à lesma marinha Elysia viridis e os seus cleptoplastos [PDF]

, 2023
Some sea slugs from the group Sacoglossa have a particular ability known as kleptoplasty i.e., the capacity to “steal” and use chloroplasts (herein kleptoplasts) from the algae they eat.

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
