Endosymbiosis: Bacteria Sharing the Load [PDF]

open access: yesCurrent 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.

Novel Trypanosomatid-Bacterium Association: Evolution of Endosymbiosis in Action [PDF]

open access: yes, 2016
UnlabelledWe describe a novel symbiotic association between a kinetoplastid protist, Novymonas esmeraldas gen. nov., sp. nov., and an intracytoplasmic bacterium, "Candidatus Pandoraea novymonadis" sp.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, Volume 293, Issue 10, Page 2908-2927, May 2026.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Plastid endosymbiosis: sources and timing of the major events

open access: yes
This chapter reviews the current ideas regarding the origin of plastids in eukaryotes and the timing of these events, with particular emphasis on the initial source of eukaryotic photosynthesis.

The Morphology and Small Subunit rDNA Gene Phylogeny of the Novel Goniomonad Genus Ebisugoniomonas and Two Novel Poseidogoniomonas Species

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Goniomonads are representatives of Cryptista. They are morphologically and genetically diverse, comprising nine genera described so far. 18S rDNA data has revealed at least one more monophyletic genus‐level lineage, as well as novel species within currently described genera. The molecular diversity of goniomonads is not fully investigated, and

A Specific Sinorhizobium Flagellin Suppresses Legume Nodulation Through Immune Activation

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3441-3457, May 2026.
ABSTRACT Bacterial flagellin‐activated immunity plays a crucial role in shaping plant‐microbe interactions, leading to either parasitism, mutualism, or commensalism. In the legume‐rhizobium symbiosis, while it has been hypothesized that rhizobial infection involves avoidance of plant immunity following flagellin perception, direct evidence supporting ...

Detecting the Diversity of Mycoplasma and Ureaplasma Endosymbionts Hosted by Trichomonas vaginalis Isolates

open access: yesFrontiers in Microbiology, 2017
Objectives: The symbiosis of Trichomonas vaginalis and Mycoplasma hominis is the first described association between two obligate human parasites. Trichomonas is the niche and the vector for the transmission of M. hominis infection.

Shining a Light on Exploitative Host Control in a Photosynthetic Endosymbiosis [PDF]

open access: yes, 2016
Endosymbiosis allows hosts to acquire new functional traits such that the combined host and endosymbiont can exploit vacant ecological niches and occupy novel environments [1, 2]; consequently, endosymbiosis affects the structure and function of ...

Plastid origin: who, when and why?

open access: yesActa Societatis Botanicorum Poloniae, 2014
The origin of plastids is best explained by endosymbiotic theory, which dates back to the early 1900s. Three lines of evidence based on protein import machineries and molecular phylogenies of eukaryote (host) and cyanobacterial (endosymbiont) genes point
