Figure 1From: Auxin secretion by Bacillus amyloliquefaciens FZB42 both stimulates root exudation and limits phosphorus uptake in Triticum aestivumSeed dressing with B. amyloliquefaciens FZB42 stimulates increased root production but reduced Pi uptake per root surface area in low Pi soils but not high Pi soils. A-B Total length of each root class per plant for three-week-old plants seed dressed at sowing with either B. amyloliquefaciens FZB42 or LB media as the untreated control and grown in either low Pi (A) or high Pi soil (B). C-D The total plant Pi content of the treatments in A and B, expressed as total Pi acquired after three weeks per root surface area. For A - D, n > 23 for each treatment, and *marks values significantly different from the untreated control values using Student’s t-test (p < 0.05). Error bars are standard errors of the mean (SEM).Back to article page
