Taimelevikutel

Taimelevikutel is a term used in Estonian plant science to describe the collective microbiota that live in association with plants, particularly on leaf surfaces (the phyllosphere) and inside plant tissues (the endosphere). It is an ecological descriptor rather than a formal taxonomic group, capturing the idea of a plant-associated microbial community as a whole.

Composition of taimelevikutel includes bacteria, fungi, archaea, yeasts, and, in some contexts, algae and protists. Common bacterial groups found in plant-associated communities include members of Pseudomonas, Bacillus, and Sphingomonas, while fungal components often comprise Ascomycota and Basidiomycota such as Cladosporium and Aureobasidium. The exact membership varies with plant species, tissue type, environmental conditions, and agricultural practices.

Ecology and function range from beneficial to neutral or pathogenic, depending on context. Taimelevikutel can contribute to nutrient cycling, growth promotion, disease suppression, and enhanced stress tolerance, while some members may act as pathogens under certain conditions. Interactions within the community and with the host plant are shaped by plant genotype, climate, soil features, and management.

Study and applications: researchers study taimelevikutel through sampling of leaf surfaces and internal tissues, surface sterilization when needed, and analyses such as 16S rRNA gene sequencing, ITS sequencing, and metagenomics. In agriculture, manipulating the plant microbiome—via inoculants, crop rotation, and reduced chemical inputs—offers potential benefits for yield and resilience, though it requires careful assessment to avoid unintended pathogen effects.
