Comparison of microbial community structure (mean±SD, n = 3) of the rhizospheric soils of rice under different doses of N-fertilizer treatment with and/or without application of endophytic fungus Phomopsis liquidambari B3.
Rice seedling subjected under the following six treatment vs C: Control; ON: Optimum N-fertilizer; LN: Low doses of N-fertilizer; CE: Control + P. liquidambari; LNE: Low N-fertilizer + P. liquidambari; ONE: Optimum N-fertilizer + P. liquidambari. G+/G, the ratios of gram-positive to gram-negative bacteria; Sat/mono, the ratios of normal saturated to monounsaturated fatty acids; Iso/anteiso, the ratios of iso- to anteiso-branched fatty acids; F/B, the ratios of fungi to bacteria; trans/cis, the ratios of trans to cis fatty acids. The different letter on the top of the column indicates a statistically significant difference between the treatments at P < 0.05 level using one-way ANOVA.
