Abstract
Volatile organic compounds play an important role in the communication between plants and other organisms. The rhizosphere contains a large and diverse microbial community whose members use similar volatiles for intra- and interspecific communication. However, the analysis of volatiles produced in the rhizosphere and their ecological functions have been little explored so far. In this chapter, we outline what is known about the classes of volatiles that are emitted into the rhizosphere by roots and soil microbes, and the effect they have on different interactors in the soil. Additionally, we review current approaches to sample volatiles in mesocosms and field soils. We conclude that to better understand the production and functions of volatiles in the rhizosphere, it is of critical importance to design set-ups that account for the natural complexity of soils. This will help to apply this knowledge for sustainable agriculture and the identification of novel agrochemicals.
