Identification of sequestered chloroplasts in photosynthetic and non-photosynthetic sacoglossan sea slugs (Mollusca, Gastropoda) [PDF]

, 2014
BACKGROUND: Sacoglossan sea slugs are well known for their unique ability among metazoans to incorporate functional chloroplasts (kleptoplasty) in digestive glandular cells, enabling the slugs to use these as energy source when starved for weeks and ...

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 ...

Different Elemental Compositions and Potential Functions of Vacuoles in Bolivina spissa (Foraminifera, Rhizaria) Based on Cryo‐SEM‐EDS Analyses

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Benthic Foraminifera exhibit diverse adaptations to low oxygen (O2) environments, including denitrification, a rare trait among eukaryotes. Denitrifying species store intracellular nitrate (NO3−), possibly within vacuoles, and contribute significantly to the global marine nitrogen (N) cycle.

Functional kleptoplasty in a limapontioidean genus: phylogeny, food preferences and photosynthesis inCostasiella, with a focus onC. ocellifera(Gastropoda: Sacoglossa) [PDF]

Journal of Molluscan Studies, 2014
The evolution and origin of functional kleptoplasty (sequestration and retention of functional plastids) within the Sacoglossa is still controversial. While some authors have suggested that it is a synapomorphy of the parapodia-bearing Plakobranchoidea, others have suggested an earlier origin at the base of the more inclusive clade Plakobranchacea.

Why it is time to look beyond algal genes in photosynthetic slugs [PDF]

, 2015
Eukaryotic organelles depend on nuclear genes to perpetuate their biochemical integrity. This is true for mitochondria in all eukaryotes and plastids in plants and algae.

Retention of blue‐green cryptophyte organelles by Mesodinium rubrum and their effects on photophysiology and growth

Journal of Eukaryotic Microbiology, Volume 72, Issue 2, March/April 2025.
Abstract As chloroplast‐stealing or “kleptoplastidic” lineages become more reliant on stolen machinery, they also tend to become more specialized on the prey from which they acquire this machinery. For example, the ciliate Mesodinium rubrum obtains > 95% of its carbon from photosynthesis, and specializes on plastids from the Teleaulax clade of ...

Prey morphotype and abundance controls plastid retention and bloom dynamics for a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 69, Issue 11, Page 2732-2747, November 2024.
Abstract Dinophysis is an obligate mixotroph that relies on consumption of the ciliate, Mesodinium rubrum, to grow and form harmful algal blooms (HABs). In this study, blooms of Dinophysis acuminata in two NY, USA, estuaries were studied over the course of 3 yr (2019–2021) using discrete samples and an Imaging FlowCytobot (IFCB) to capture images of ...

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.

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.

Distinct Bleaching Resilience of Photosynthetic Plastid-Bearing Mollusks Under Thermal Stress and High CO2 Conditions

Frontiers in Physiology, 2018
The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling
