A holobiont is a collection of closely associated species that have complex interactions, such as a plant species and the members of its microbiome. [2] [9] Each species present in a holobiont is a biont, and the genomes of all bionts taken together are the hologenome, or the "comprehensive gene system" of the holobiont. [10]
This concept has been demonstrated for land plants, where root exudates manipulate microbiome composition. [89] In marine environments, the phylogenetic diversity of hosts and symbionts suggests both conserved and marine-specific chemical interactions, but studies are still in their infancy.
Environmental factors act at multiple scales to alter microbiome, holobiont, community, and ecosystem scale processes. Thus, factors that alter microbiome functioning can lead to changes at the holobiont, community, or even ecosystem level and vice versa, illustrating the necessity of considering multiple scales when evaluating functioning in ...
The stable, beneficial plant microbiome may be altered to facilitate the development of certain diseases, as observed in the olive knot disease. [ 16 ] As functional macrobes living in a close association with diverse communities of microbes and viruses, plants should be considered a "holobiont", viewed as a complex system in continuous ...
One of the important outcomes of recasting the individual as a holobiont subject to evolutionary forces is that genetic variation in the hologenome can be brought about by changes in the host genome and also by changes in the microbiome, including new acquisitions of microbes, horizontal gene transfers, and changes in microbial abundance within ...
Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
Additionally, these products disrupt the nutrient cycles of phosphorus and nitrogen and reduce the diversity of the soil microbiome. Given the challenges posed by a growing global population and the need for more and higher-quality food, the future of agriculture lies in using effective microorganisms to boost yields. This approach offers a ...
This microbiome's predicted carbohydrate-degrading enzyme profile is similar to that of the bovine rumen, but the species composition is almost entirely different. [40] Gut microbiota of the fruit fly can affect the way its gut looks, by impacting epithelial renewal rate, cellular spacing, and the composition of different cell types in the ...
