Abstract
Plant microbiome interactions are bidirectional with processes leading to microbiome assembly and processes leading to effects on plants, so called microbiome feedbacks. With belowground focus we systematically decomposed both of these directions into plant and (root and rhizosphere) microbiome components to identify methodological challenges and research priorities. We found that the bidirectionality of plant microbiome interactions presents a challenge for genetic studies. Establishing causality is particularly difficult when a plant mutant has both, an altered phenotype and an altered microbiome. Is the mutation directly affecting the microbiome (e.g., through root exudates), which then causes an altered phenotype of the plant and/or is the altered microbiome the consequence of the mutation altering the plant's phenotype (e.g., root architecture)? Here, we put forward that feedback experiments allow to separate cause and effect and furthermore, they are useful for investigating plant interactions with complex microbiomes in natural soils. They especially allow to investigate the plant genetic basis how plants respond to soil microbiomes and we stress that such microbiome feedbacks are understudied compared to the mechanisms contributing to microbiome assembly. Thinking towards application, this may allow to develop crops with both abilities to assemble a beneficial microbiome and to actively exploit its feedbacks.
