| Abstract: |
| Soil-borne diseases are a common impediment to the sustainable development of agriculture worldwide. The rhizosphere microbiome plays an important role in the development of immune barriers against the invasion of soil pathogens. Rhizosphere microbes not only compete for nutrition and produce diffusible antimicrobial compounds, but also interact with other microorganisms and plants by secreting microbial volatile organic compounds（mVOCs）that play a role in disease suppression. Owing to the low effective concentration and long-distance diffusion at the water-soil-air interface, mVOCs have become a hot spot not only for mechanistic research but also for product development in the prevention and control of soil-borne diseases. In this review, we briefly discuss the initial reports describing the involvement of mVOCs in soil disease inhibition, and then systematically discuss the current advances in mVOCs research, specifically：the production of microbes with disease inhibition ability from indoor and field evidence; the mechanism of mVOCs participating in rhizosphere immunity, including suppression of pathogen growth and virulence traits; the microbial interactions in the rhizosphere; and the induction of plant resistance. We also analyzed the biotic and abiotic factors of soil affecting the production of mVOCs and proposed future research directions and theoretical and practical prospects relating to how to improve rhizosphere immunity against soil-borne plant diseases. |
