Abstract
Many interactions between organisms are based on the emission and perception of volatiles The principle of using volatile metabolites as communication signals for chemoattractant or repellent for speciesspecific interactions or mediators for celltocell recognition does not stop at an apparently unsuitable or inappropriate environment These infochemicals do not only diffuse through the atmosphere to process their actions aboveground but belowground volatile interactions are similarly complex This review summarizes various eucaryotes eg plant roots invertebrates fungi and procaryotes eg rhizobacteria which are involved in these volatilemediated interactions The soil volatiles cannot be neglected anymore but have to be considered in the future as valuable infochemicals to understand the entire integrity of the ecosystems
