Fig. 5. SynCom C induces salt stress tolerance related responses in tomato.

Fig. 5

Tomato seeds were sown in sterilized river sand and inoculated with the five-member SynCom C or the five individual strains. Plants were exposed to 200 mM NaCl on day seven. The root and shoot tissue were harvested on four, seven, and ten days post salt imposition. a Shoot fresh weight of the tomato plants for the three time points after salt imposition. A linear model was fitted to the biomass with the time points and inoculation as the explanatory variables. Only the SynCom C treated samples had a significantly different (p < 0.05) slope from the inoculum-free control samples. b Relative expression of salt stress resilience-related genes to Actin in the root tissue of tomato plants four days post salt imposition. An asterisk indicates a significant (p < 0.05) difference from the control, according to Dunnett’s test. c The Na+/K+ ratio in the shoot of tomato plants ten days post salt imposition. SynCom C inoculated plants had a significantly lower ratio than the control (tested with Student’s t test). SynCom C is composed of the strains Massilia sp. SA087, Enterobacter sp. SA187, Ensifer sp. SA403, Bacillus sp. SA436 and Streptomyces sp. SA444.
