Mechanisms underlying soil chemical properties and microorganism-mediated effects on the accumulation of monoterpenes. a Rhizosphere soil was enriched in salinity-tolerant microorganisms with the capacity for terpene biosynthesis. b, c A special soil environment (high salinity, Mg, Mn and K) enhances the monoterpenoid content by promoting the expression of salt stress-responsive genes and activities of terpene backbone synthase. d SynCom boosts the accumulation of monoterpenes in the leaves of C. reticulata ‘Chachi’ in an immune-dependent manner. e We assumed that the rhizosphere soil and endophyte bacteria co-contributed to the accumulation of monoterpenes by triggering the plant immune response or providing intermediate products for the plant.
