Bacterial Volatile in Rhizosphere

Abstract

Investigation on antagonism, to follow competition between target pathogen and biocontrol agent is the main step to select the effective candidate in vitro and in vivo conditions. Rhizosphere is a harbour of bacteria and fungi. Their interactions and ongoing communication network are in balance and continued with prominent molecules mediating this signal traffic ‘volatile organic compounds’ (VOCs). Volatile compounds emitted by different soil bacteria affect the growth of plants and gene expression. Bacterial volatiles can have an important role in communication and antagonistic interactions within the soil bacterial community. In this complicated microflora, to decipher the chemical language through microbial interactions will be beneficial for sustainable control measurements. Here we evaluated volatile-mediated interactions of a microbial community mimicking the natural conditions in the heterogeneous soil environment along the rhizosphere. This chapter summarizes biological and ecological significance of VOC-mediated resistance and briefly provides updated knowledge on this concept.
