Diversity in biosynthetic pathways of galactolipids in the light of endosymbiotic origin of chloroplasts

Frontiers in Plant Science, 2016
Cyanobacteria and chloroplasts perform oxygenic photosynthesis, and share a common origin. Galactolipids are present in the photosynthetic membranes of both cyanobacteria and chloroplasts, but the biosynthetic pathways of the galactolipids are ...

Endosymbiosis: Bacteria Sharing the Load [PDF]

Current Biology, 2011
A nested set of bacterial endosymbionts within mealybug cells collectively provides amino acids to their host, but their genomes show that some pathways are distributed between both endosymbionts, while other essential proteins are missing altogether.

Endosymbiosis

Abstract All eukaryotes harbor one or more remnants of ancient bacterial-derived endosymbionts, all of which have experienced considerable reduction in genome size. The colonization of an alphaproteobacterium in the stem eukaryote ultimately became the mitochondrion, to which membrane bioenergetics were relocated from the plasma membrane

The roles of dispersal limitation and pre-adaptation in shaping Paraburkholderia endosymbiont frequencies in social amoeba communities

Applied and Environmental Microbiology
Endosymbiotic interactions have long played fundamental roles in shaping the evolution and diversification of eukaryotes. However, we still have a limited understanding of how ecological processes govern the distribution of endosymbionts that are still ...

Metabolic pathway redundancy within the apicomplexan-dinoflagellate radiation argues against an ancient chromalveolate plastid

Communicative & Integrative Biology, 2016
The chromalveolate hypothesis presents an attractively simple explanation for the presence of red algal-derived secondary plastids in 5 major eukaryotic lineages: “chromista” phyla, cryptophytes, haptophytes and ochrophytes; and alveolate phyla ...

Molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs

Frontiers in Microbiology, 2014
Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug endosymbiotic systems whose genomes have been

In Vitro Culture of the Insect Endosymbiont Spiroplasma poulsonii Highlights Bacterial Genes Involved in Host-Symbiont Interaction

mBio, 2018
Endosymbiotic bacteria associated with eukaryotic hosts are omnipresent in nature, particularly in insects. Studying the bacterial side of host-symbiont interactions is, however, often limited by the unculturability and genetic intractability of the ...

The Symbiosome: Legume and Rhizobia Co-evolution toward a Nitrogen-Fixing Organelle?

Frontiers in Plant Science, 2018
In legume nodules, symbiosomes containing endosymbiotic rhizobial bacteria act as temporary plant organelles that are responsible for nitrogen fixation, these bacteria develop mutual metabolic dependence with the host legume.

Stochastic Fluctuations of the Facultative Endosymbiont Wolbachia due to Finite Host Population Size

Ecology and Evolution
Many insects and other animals host heritable endosymbionts that alter host fitness and reproduction. The prevalence of facultative endosymbionts can fluctuate in host populations across time and geography for reasons that are poorly understood.
