Of the many ways that plants interact with microbes, three aspects are highlighted in this issue: interactions where the plant benefits from the microbes, interactions where the plant suffers, and interactions where the plant serves as habitat for microbial communities. In this editorial, the fourteen articles published in the Special Issue Plant⁻Microbe Interaction 2017 are summarized and discussed as part of the global picture of the current understanding of plant-microbe interactions.
Keywords: Streptomyces; comparative methods; effectors; microbiome; phytoremediation; plant growth-promoting bacteria; plant–microbe interactions; rhodopsins; transcriptome.
