Figure 3From: Auxin secretion by Bacillus amyloliquefaciens FZB42 both stimulates root exudation and limits phosphorus uptake in Triticum aestivumB. amyloliquefaciens FZB42 treatment effects on expression of root Pi transporters, and genes involved in internal Pi metabolism. A Relative expression of T. aestivum PHT1 genes, in roots, standardised to actin (ACT) controls. The experimental treatments were: inoculation with B. amyloliquefaciens FZB42, treatment with 1 µM IAA and untreated controls. B Relative expression of T. aestivum Pi metabolism genes in roots, standardised to actin (ACT) controls with the same treatments as in A. For A and B n = 3 for each treatment, error bars are SEM, and * marks values significantly different from the untreated control value using Student’s t-test (p < 0.05).Back to article page
