Symbiogenesis is the result of the permanent coexistence of various bionts to form the holobiont (namely, the host and its microbiota). The holobiome is the sum total of the component genomes in a eukaryotic organism; it comprises the genome of an individual member of a given taxon (the host genome) and the microbiome (the genomes of the symbiotic microbiota). The latter is made up of the genes of a variety of microbial communities that persist over time and are not eliminated by natural…

The importance of the microbiome of the plant holobiont.

It is suggested that the plant can modulate its microbiota to dynamically adjust to its environment and to better understand the level of plant dependence on the microbiotic components, the core microbiota need to be determined at different hierarchical scales of ecology while pan-microbiome analyses would improve characterization of the functions displayed.

The hologenome concept of evolution : a philosophical and biological study

This thesis constitutes a conceptual effort to defend philosophically the hologenome concept, arguing that the criticism according to which holobiont selection requires tight transgenerational host-genotypes-to-symbiont-genotype connection is grounded on a metaphysical view of the worldAccording to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below.

The holobiont concept: the case of xylophagous termites and cockroaches

This review describes the relationships between xylophagous insects and their microbiota in an attempt to understand the characteristics that have determined bacterial fidelity over generations and throughout evolutionary history.

Holobiont Evolution: Model with Vertical vs. Horizontal Microbiome Transmission

According to both variants, holobiont selection is plausibly an important evolutionary force with either mode of microbiome transmission, and a new concept of inheritance emerges from the model: collective inheritance whereby juveniles inherit a sample of the collected genomes of all parents as contrasted with traditional lineal inheritance.

Modeling the Role of the Microbiome in Evolution

This is the first model in which symbiotic interactions, diversity, specialization and dysbiosis in an ecosystem emerge as a result of coevolution, which helps to understand the emergence of complex organisms, as they adapt more easily to perform multiple tasks than non-complex ones.

Symbiogenesis: Beyond the endosymbiosis theory?

Can We Understand Evolution Without Symbiogenesis

This chapter provides information on some of the key figures and their major works on symbiosis and symbiogenesis and reinforces the importance of these concepts in the understanding of the natural world and the role they play in the establishing of the evolutionary complexity of living systems.

Holobiont Evolution: Population Theory for the Hologenome

Host-orchestrated species sorting followed by microbial competition, rather than co-evolution or multi-level selection, is predicted to be the cause of microbiome-host integration.

Holobiont Evolution: Mathematical Model with Vertical vs. Horizontal Microbiome Transmission

This paper presents two variants of a simple mathematical model that employs two distinct concepts of inheritance, depending on the mode of microbiome transmission: collective inheritance whereby juveniles inherit a sample of the collected genomes from all parents, as contrasted with lineal inheritance whereby youngsters inherit the genomes from only their own parents.



Role of microorganisms in the evolution of animals and plants: the hologenome theory of evolution.

The hologenome theory of evolution considers the holobiont (the animal or plant with all of its associated microorganisms) as a unit of selection in evolution and fits within the framework of the 'superorganism' proposed by Wilson and Sober.

Complete genome of the uncultured Termite Group 1 bacteria in a single host protist cell

The first complete genome sequence of a termite gut symbiont—an uncultured bacterium named Rs-D17 belonging to the candidate phylum Termite Group 1—is presented, suggesting that this bacterial group plays a key role in the gut symbiotic system by stably supplying essential nitrogenous compounds deficient in lignocelluloses to their host protists and the termites.

The Hologenomic Basis of Speciation: Gut Bacteria Cause Hybrid Lethality in the Genus Nasonia

It is concluded that in this animal complex, the gut microbiome and host genome represent a coadapted “hologenome” that breaks down during hybridization, promoting hybrid lethality and assisting speciation.

The gut bacteria of insects: nonpathogenic interactions.

The intestinal bacteria is discussed in the context of developing understanding of symbiotic relationships, of multitrophic interactions between insects and plant or animal host, and in developing new strategies for controlling insect pests.

Cospeciation in the triplex symbiosis of termite gut protists (Pseudotrichonympha spp.), their hosts, and their bacterial endosymbionts

The members of this triplex symbiotic system appear to have cospeciated during their evolution with minor exceptions; the evolutionary relationships were probably established by termite sociality and the complex microbial community in the gut.

The genome of SOPE, the obligate mutualistic endosymbiont of rice weevils, was used as a model to analyze the initial events that occur after symbiotic integration and its relevance as a source of gene inactivation, chromosomal rearrangements, and as participants in the genome reductive process is discussed herein.
