Synthetic communities boost the accumulation of monoterpenes in the leaves of C. reticulata ‘Chachi’. a Relative abundance of Pseudomonas, Streptomyces, Stenotrophomonas and Serratia in the rhizosphere. Significance is indicated between core and non-core regions by the Wilcoxon rank sum test. b The treatment of nine groups of C. reticulata ‘Chachi’ with different treatments. Strep-4 from Streptomyces, Steno-6 from Stenotrophomonas, Pseud-1 from Pseudomonas and Serra-11 from Serratia. c The content of four monoterpenes in C. reticulata ‘Chachi’ leaves after inoculation with Strep-4 and its SynComs. Different letters denote a significant difference (LSD, P < 0.05). d The relative abundance of the DXS gene in C. reticulata ‘Chachi’ leaves was measured by qRT–PCR. e Differentially expressed genes in citrus leaves after inoculation with Strep-4 and its SynComs
