The microbiome of peatland plants : literature review

The aggregate of various taxonomic groups of microorganisms colonising living organisms is known as the microbiome. The plant microbiome encompasses a wide network of biological, chemical and metabolic interactions between the plant and microorganisms (mainly algae, bacteria and protozoa). The relationships between microbes and peatland plants, particularly carnivorous plants, are a very interesting subject that is still little understood. Microbes colonising carnivorous peatland plants may be present in their traps or on the surface of the plant. Previous research on the relationships between the microbiome composition of carnivorous plants and the external factors influencing it directly and indirectly is still inadequate. There is a lack of review articles analysing the current state of knowledge regarding carnivorous plant-microbiome interactions. This review of the literature is a collection of data on the functioning of the microbiome of carnivorous plants growing in peatland ecosystems. In addition, it summarises the available information on host–microorganism relationships.
