Test of B. altitudinis WR10 stress alleviating potential under either high saline or low phosphorus: (a), relative germination rate (RGR) of wheat seeds under high saline; (b), roots dry weight (RDW) of wheat seedlings under low phosphorus. The RGR of wheat seeds (n = 25) was calculated for evaluating salinity stress alleviating potential after culturing for one week under different concentration of NaCl (0, 100, 200, and 400 mM). Co-cultures were performed in Hoagland’s medium and the final cell density of WR10 was adjusted to 106 cfu/mL. The RDW of wheat seedlings (n = 15) was recorded after two-week culture in a modified half-strength Hoagland’s medium without phosphorus resource, unless with extra addition of 10 μM KH2PO3 and other different phosphate resources (250 μM Ca3(PO4)2 or 100 μM calcium phytate). All roots from each plant were collected and oven dried before weighing RDW. Data are the mean of three independent experiments. Statistical analysis was performed using one-way ANOVA with Bonferroni post-test (*** p < 0.001).
