As a soil-borne fungus, microsclerotia of V. longisporum can stay viable in the soil for long periods of time in a dormant form. This temporally inactive phase of pathogen can be broken by some environmental factors. Studies have revealed that root exudates stimulate germination of V. longisporum microsclerotia and direct hyphae to the host roots. However, the exact compound (s) inducing germination of the dormant microsclerotia and the underlying mechanism still remain unclear. Therefore, the main objective of this study is to identify the root exudate component (s) involved in this initial host-pathogen communication.
