Endophytes are microbes (mostly bacteria and fungi) present asymptomatically in plants. Endophytic microbes are often functional in that they may carry nutrients from the soil into plants, modulate plant development, increase stress tolerance of plants, suppress virulence in pathogens, increase disease resistance in plants, and suppress development of competitor plant species. Endophytic microbes have been shown to: (i) obtain nutrients in soils and transfer nutrients to plants in the rhizophagy cycle and other nutrient‐transfer symbioses; (ii) increase plant growth and development; (iii) reduce oxidative stress of hosts; (iv) protect plants from disease; (v) deter feeding by herbivores; and (vi) suppress growth of competitor plant species. Because of the effective functions of endophytic microbes, we suggest that endophytic microbes may significantly reduce use of agrochemicals (fertilizers, fungicides, insecticides, and herbicides) in the cultivation of crop plants. The loss of endophytic microbes from crop plants during domestication and long‐term cultivation could be remedied by transfer of endophytes from wild relatives of crops to crop species. Increasing atmospheric carbon dioxide levels could reduce the efficiency of the rhizophagy cycle due to repression of reactive oxygen used to extract nutrients from microbes in roots. © 2019 The Authors.

1. Multiple drivers of environmental change pose a significant challenge for ecological restoration, including climate change, soil salinization and environmental pollution. Due to the important role that soil biota play in enabling plants to cope with a variety of abiotic stressors, there is growing interest in the use of microbial inoculations to facilitate native plant restoration in the face of such change. 2. Recently, novel methods have begun being explored in agriculture to harness stressconditioned soil biota for improving abiotic stress tolerance in crop species. Similar applications in ecological restoration-where plants are inoculated with indigenous soil microbial communities that are preconditioned to various abiotic stressors-could potentially increase our capacity to restore degraded ecosystems under global change. 3. In this paper, we aim to (1) outline the ways in which soil microbial communities might be conditioned in order to confer greater stress tolerance to plants that are targets for restoration; (2) highlight successful (and unsuccessful) examples where stress-tolerant soil microbial communities were utilized to improve plant performance; (3) describe the ways in which stress-conditioned soil biota could be deployed in order to assist ecological restoration; and (4) discuss the potential risks and outstanding questions associated with such an approach. 4. If restoration practitioners are able to harness the soil microbiome to improve plant stress tolerance as is currently being explored in agriculture, this could revolutionize methods for the restoration of degraded lands in the Anthropocene.

Endophytes are defined as microorganisms colonising the interior of plants without causing disease. They comprise mainly fungi and bacteria, and their lifestyle range from merely receiving shelter and nutrients from the host to interactions benefitting both themselves and the host plant. In recent years, there has been an increased interest in understanding the communities of organisms inside plants; how they influence the host and how they can be utilised to benefit plants and humans. Therefore, the transmission and recruitment of endophytes, as well as methods to study the composition of endophytic communities, are important issues for successful exploitation. Beneficial effects include protection against biotic stress caused by pests and pathogens as well as against abiotic stress, for instance, drought, salinity and temperature. Furthermore, endophytes can promote growth by production of plant hormones and nutrient acquisition and some endophytes can be used for bioremediation and production of pharmaceuticals and nutraceuticals. Key Concepts Endophytes are organisms living inside plants without causing disease. Most endophytes are commensalistic, but some are mutualistic. Most endophytes are bacteria and fungi. Endophyte communities can be studied by culture‐dependent and culture‐independent methods. Recruitment of endophytes can be from environment or from mother plants. Endophytes can protect plants from biotic and abiotic stress. Endophytes can help in nutrient acquisition for the plant and cause growth promotion. Endophytes can help in bioremediation and participate in the production of specialised metabolites with industrial application.
