tRNA functional signatures classify plastids as late-branching cyanobacteria. [PDF]

open access: yes, 2019
BackgroundEukaryotes acquired the trait of oxygenic photosynthesis through endosymbiosis of the cyanobacterial progenitor of plastid organelles. Despite recent advances in the phylogenomics of Cyanobacteria, the phylogenetic root of plastids remains ...

The Microbiome Within a Microbe: Rethinking Blastocystis Biology. [PDF]

open access: yesJ Eukaryot Microbiol
ABSTRACT Blastocystis spp., one of the most prevalent microeukaryotes in the human gut, has long puzzled researchers with its ambiguous role in health and disease. Decades‐old microscopy studies reported bacterial‐ and viral‐like particles within Blastocystis spp. cells, but these findings have been mainly overlooked.

Biosynthesis of fucoxanthin and diadinoxanthin and function of initial pathway genes in Phaeodactylum tricornutum [PDF]

open access: yes, 2012
The biosynthesis pathway to diadinoxanthin and fucoxanthin was elucidated in Phaeodactylum tricornutum by a combined approach involving metabolite analysis identification of gene function.

Inhibitory to non-inhibitory evolution of the ζ subunit of the F1FO-ATPase of Paracoccus denitrificans and α-proteobacteria as related to mitochondrial endosymbiosis

open access: yesFrontiers in Molecular Biosciences, 2023
Introduction: The ζ subunit is a potent inhibitor of the F1FO-ATPase of Paracoccus denitrificans (PdF1FO-ATPase) and related α-proteobacteria different from the other two canonical inhibitors of bacterial (ε) and mitochondrial (IF1) F1FO-ATPases.

Engineering Mycorrhizal Symbioses to Alter Plant Metabolism and Improve Crop Health

open access: yesFrontiers in Microbiology, 2017
Creating sustainable bioeconomies for the 21st century relies on optimizing the use of biological resources to improve agricultural productivity and create new products. Arbuscular mycorrhizae (phylum Glomeromycota) form symbiotic relationships with over

Roman roads: The hierarchical endosymbiosis of cognitive modules [PDF]

open access: yes, 2009
Serial endosymbiosis theory provides a unifying paradigm for examining the interaction of cognitive modules at vastly different scales of biological, social, and cultural organization.

Coral lipid bodies as the relay center interconnecting diel-dependent lipidomic changes in different cellular compartments

open access: yesScientific Reports, 2017
Lipid bodies (LBs) in the coral gastrodermal tissues are key organelles in the regulation of endosymbiosis and exhibit a diel rhythmicity. Using the scleractinian Euphyllia glabrescens collected across the diel cycle, we observed temporally dynamic lipid

Organellar Evolution: A Path from Benefit to Dependence

open access: yesMicroorganisms, 2022
Eukaryotic organelles supposedly evolved from their bacterial ancestors because of their benefits to host cells. However, organelles are quite often retained, even when the beneficial metabolic pathway is lost, due to something other than the original ...

Protein import into the endosymbiotic organelles of apicomplexan parasites [PDF]

open access: yes, 2018
The organelles of endosymbiotic origin, plastids, and mitochondria, evolved through the serial acquisition of endosymbionts by a host cell. These events were accompanied by gene transfer from the symbionts to the host, resulting in most of the organellar

Wolbachia injection from usual to naive host in Drosophila simulans (Diptera: Drosophilidae)

open access: yesEuropean Journal of Entomology, 2001
Wolbachia pipientis (Hertig) (Rickettsiaceae) is an endocellular bacterium infecting numerous species of arthropods. The bacterium is harboured by males and females but is only transmitted maternally because spermatocytes shed their Wolbachia during ...
