Fig. 4: Screening of growth-promoting strains and construction of SynComs.
From: Superiority of native soil core microbiomes in supporting plant growth
a Evaluation of growth-promoting effect and properties of ten strains on tobacco. The asterisk on the bar chart means significantly higher than the control (n = 9, P < 0.01, one-way ANOVA test). b Construction of SynComs and pair interaction of growth-promoting bacteria. The size of the circle represents OD(YC+ supernatant)/OD(YC), and the growth-promoting effect of the supernatant on the other bacteria becomes stronger with the increase of the circle. c Survival status of the SynComs in the medium during cultivation of 15 days (n = 3). d Determination of SynComs stability in vitro and niche breadth index (n = 15, P < 0.01, one-way ANOVA test). AVD, average variation degree. Different letters on the boxplot indicate significant differences between treatments. Each bar represents the mean ± SD.
