Plant-associated microorganisms may be invisible to the naked eye, yet they play a key role in the future sustainability of terrestrial ecosystems. It is now widely recognized that global environmental changes dramatically impact plant diversity, fitness and physiology. However, plants are not living alone, they are supra-organisms hosting a wide range of commensal, beneficial and detrimental microorganisms. Describing, understanding and predicting the impacts of anthropogenically-driven environmental changes on plant–microbe interactions, plant adaptions and microbial functions is therefore a scientific and societal challenge. This Special Issue provides a platform for discussion on this topic and the papers in this collection are intended to highlight and further stimulate research on the functioning and role of the plant microbiota, and its interaction with plants under global environmental change stress. The articles cover interactions of plants with a wide range of microbes, including above- and below-ground interactions, and from the molecular to ecosystem-level scale.
