Nitrate Assimilation Underlying Kleptoplasty

2022
Abstract While photoautotrophic organisms utilize inorganic nitrogen as the nitrogen source, heterotrophic organisms utilize organic nitrogen and thus do not generally have an inorganic nitrogen assimilation pathway. Here we focused on the nitrogen metabolism of Rapaza viridis , a ...

Secondary and Tertiary Endosymbiosis and Kleptoplasty

Advances in Photosynthesis and Respiration, 2012
Alga is an informal name that refers to a diverse group of photosynthetic eukaryotes that have a polyphyletic origin in the tree of life. Although genomics has provided powerful tools for understanding the evolution of algal photosynthesis many issues remain unresolved. These include explaining the intermingling of plastid-lacking taxa such as ciliates

Laboratory culturing of Elysia chlorotica reveals a shift from transient to permanent kleptoplasty

Symbiosis, 2012
The kleptoplastic sacoglossan Elysia chlorotica shares a requisite, intracellular symbiosis with the plastids (= chloroplasts) of the Xanthophyte alga Vaucheria litorea. Although wild specimens have been used to address a range of biological questions, no studies have thoroughly characterized animal development during the initial establishment of the ...

Phylogenetic evidence for multiple independent origins of functional kleptoplasty in Sacoglossa (Heterobranchia, Gastropoda)

Organisms Diversity and Evolution, 2014
Sacoglossa is a rather small taxon of marine slugs with about 300 described species, yet it is quite fascinating scientists for decades. This is mainly because of the ability of certain species to incorporate photosynthetically active plastids of their algae prey, a phenomenon known as functional kleptoplasty.

Kleptoplasty: Letting the cart lead the horse

Current Biology
Some chloroplast-stealing dinoflagellates remodel their kleptoplastids, form an extensive network with stollen mitochondria, and likely benefit from photosynthetic genes that they inherited or acquired from prey. These adaptations allow these protists to exploit kleptoplastids for months and shed light on past plastid acquisitions.

Molecular Phylogeny of the Sacoglossa, With a Discussion of Gain and Loss of Kleptoplasty in the Evolution of the Group

Biological Bulletin, 2010
Sacoglossan sea slugs retain the chloroplasts from food algae in their cells (kleptoplasty) and obtain the photosynthetic products, but the capability of kleptoplasty differs among species. One evolutionary hypothesis for kleptoplasty is that the family Volvatellidae is the ancestral sacoglossan lineage in which kleptoplasty arose, but this is based on

Chloroplast harvesting by a miliolid expands the evolutionary range of kleptoplasty in foraminifera 

2022
<p>Foraminifera are highly abundant marine unicellular eukaryotes. They are known for their important ecological role in most marine ecosystems, their major contribution to the carbon cycle, and their remarkable physiological plasticity.

Short-term retention of kleptoplasty from a green alga (Bryopsis) in the sea slug Placida sp. YS001

Biologia (Poland), 2014
The capacity of sea slugs (sacoglossans) for retaining chloroplasts from food algae provides important insights into endosymbiotic relationships and kleptoplasty. A sea slug species was captured accidentally in the Yellow Sea and identified as Placida sp. YS001 based on phylogenetic analyses of the COX1 and 16S gene sequence.

Kleptoplasty in an Antarctic dinoflagellate: caught in evolutionary transition?

Environmental Microbiology, 2006
Summary Photosynthetic dinoflagellates contain a diverse collection of plastid types, a situation believed to have arisen from multiple endosymbiotic events. In addition, a number of heterotrophic (phagotrophic) dinoflagellates possess the ability to acquire chloroplasts temporarily by engulfing algae and ...

Initial Observations of Kleptoplasty in the Foraminifera of Coastal South Carolina

Southeastern Naturalist, 2015
Abstract Kleptoplasty is a mixotrophic condition acquired by a heterotrophic grazer that ingests photosynthetic eukaryotic cells, wherein the plastids are not digested but rather are retained in the heterotrophic cell or organism in a photosynthetically active state.
