Effect of WR10 inoculation on the abundance of endophytic Bacillus spp. and nutrient content in different wheat tissues at the grain filling stage. (A) The relative abundance of endophytic Bacillus spp. in different wheat tissues; (B) Relative content of N in different wheat tissues; (C) Relative content of K in different wheat tissues; (D) Relative content of Fe in different wheat tissues. Content of macronutrients was calculated as mg/g, and that of micronutrients was calculated as mg/kg dry weight. Original data were analyzed by pair-wise comparisons using LDS test, and p < 0.05 was considered significant. All data in the figure were normalized to their respective counterparts in the control group (NC) without inoculation of bacteria. In spraying, soils were sprayed with B. altitudinis WR10 before sowing of wheat; in soaking, wheat seeds were soaked in B. altitudinis WR10 suspension before sowing; a, statistically different from NC; b, significantly different between spraying and soaking groups.
