Soil protistology rebooted: 30 fundamental questions to start with


•Protists are the most diverse eukaryotes in soils.
•They are key elements in the soil food web and are essential for plant functioning.
•Nevertheless, protists are highly understudied compared to other microorganisms.
•We here provide an overview of missing research gaps to guide future studies.
•This will allow bridging protistology to general microbiology and ecology in soils.
