Variation is the raw material for evolution. Without genetic variation, evolution cannot occur—no genetic variation = no evolution. To begin with, variation is a readily observable feature of the biological world—no two sisters or brothers are identical (even identical twins are not identical).

In the previous chapters, we have presented published experimental data in support of the principles upon which the hologenome concept are based. We also pointed out special aspects of the concept, such as the additional modes of genetic variation within the holobiont.

Metagenomic analysis of stressed coral holobionts
Environmental Microbiology, 2009SummaryThe coral holobiont is the community of metazoans, protists and microbes associated with scleractinian corals. Disruptions in these associations have been correlated with coral disease, but little is known about the series of events involved in the shift from mutualism to pathogenesis.

Microbiome, holobiont and the net of life
Critical Reviews in Microbiology, 2014Holistic emerging approaches allow us to understand that every organism is the result of integration mechanisms observed at every level of nature: integration of DNA from virus and bacteria in metazoans, endosymbiotic relationships and holobionts. Horizontal gene transfer events in Bacteria, Archaea and Eukaryotes have resulted in the chimeric nature ...

Molecular Delineation of Species in the Coral Holobiont
2012The coral holobiont is a complex assemblage of organisms spanning a diverse taxonomic range including a cnidarian host, as well as various dinoflagellate, prokaryotic and acellular symbionts. With the accumulating information on the molecular diversity of these groups, binomial species classification and a reassessment of species boundaries for the ...

Microbial disease and the coral holobiont
Trends in Microbiology, 2009Tropical coral reefs harbour a reservoir of enormous biodiversity that is increasingly threatened by direct human activities and indirect global climate shifts. Emerging coral diseases are one serious threat implicated in extensive reef deterioration through disruption of the integrity of the coral holobiont - a complex symbiosis between the coral ...

Osmoadjustment in the Coral Holobiont
2017Coral reefs are under considerable decline. The framework builders in coral reefs are scleractinian corals, which comprise so-called holobionts, consisting of cnidarian host, algal symbionts (genus Symbiodinium), and other associated microbes. Corals are commonly considered stenohaline osmoconformers, possessing limited capability to adjust to salinity

Disease of the holobiont, the example of multiple sclerosis
Medicina Clínica (English Edition), 2019In recent years there has been a revolution regarding the role of the microbiota in different diseases, most of them within the spectrum of inflammatory and autoimmune diseases, associated with the development of metagenomics and the concept of holobiont, a large organism together with its microbiota.

Introduction: The Holobiont Imperative
2016This book is being written at a time when fundamental shifts in thinking are occurring in the life sciences, but when the metaphorical ground has not yet settled under our feet. There are no germ-free animals in nature. Epithelia in contact with the environment are colonized by microbial communities, and all multicellular organisms must be considered ...

Symbiogenesis: the holobiont as a unit of evolution.
International microbiology : the official journal of the Spanish Society for Microbiology, 2013Symbiogenesis 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 ...
