Obligate endosymbiosis enables genome expansion during eukaryogenesis [PDF]
The endosymbiosis of an alpha-proteobacterium that gave rise to mitochondria was one of the key events in eukaryogenesis. One striking outcome of eukaryogenesis was a much more complex cell with a large genome.

Reaction Network Modeling of Complex Ecological Interactions: Endosymbiosis and Multilevel Regulation [PDF]
Endosymbiosis is a type of symbiosis where one species of microscopic scale inhabits the cell of another species of a larger scale, such that the exchange of metabolic byproducts produces mutual benefit.

Endosymbiosis: The feeling is not mutual [PDF]
Endosymbiosis is an idea that provided a remarkable amount of explanatory power about the origins of eukaryotic organelles. But it also promoted a number of assumptions that have also been influential, but are less well-examined. Here we look at two of these to see whether or not they fit current evidence.

Dynamic LHCI antenna and inter-photosystem spillover enable flexible light harvesting in Euglena gracilis. [PDF]
Significance Statement Euglena gracilis is an early diverging photosynthetic organism with a unique mosaic photosynthetic apparatus. Biochemical and spectroscopic analysis reveals a kinetically slower photosystem I sharing excitation energy with photosystem II in the absence of strict photosystem segregation.

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta. [PDF]
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...

Relationship troubles at the mitochondrial level and what it might mean for human disease [PDF]
Understanding and treating disease depend upon our knowledge of how the body works. The biomedical approach to disease describes health purely in terms of biological factors, with a focus on the genome as the molecular basis for cellular function and ...

Beyond red/far-red sensing: phytochrome perception of the marine light field by microalgae. [PDF]
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Multifunctional aspects of Piriformospora indica in plant endosymbiosis
Piriformospora indica (Hymenomycetes, Basidiomycota) is an endophytic fungus that colonises plant roots, and was originally isolated from Rajasthan desert. It is comparable to Arbuscular Mycorrhizal (AM) fungi in terms of plant growth promotional effects.

Developmental Integration of Endosymbionts in Insects
In endosymbiosis, two independently existing entities are inextricably intertwined such that they behave as a single unit. For multicellular hosts, the endosymbiont must be integrated within the host developmental genetic network to maintain the ...

Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.
