Abstract. Bacteria affect plant growth through several mechanisms. A recently describedmechanism involves the production of microbial volatile organic compounds (mVOCs),which are gaseous molecules capable of interacting with plants in the soil environment.mVOCs may promote plant growth directly, through induced resistance systemic (ISR), orindirectly through suppression of phytopatogens (biocontrol). In this chapter, we describeseveral experimental designs for evaluation of mVOCs effects on plant growth, ISR orbiocontrol mechanisms; potential problems with the methodologies and possible solutions.To date, relatively few mVOCs have been identified and their effects on plant growthcharacterized. Generally, the effect observed on a particular plant-bacterium interaction wasattributed to the pool of mVOCs produced, like an evidence of synergism among chemicalcompounds.
