^a∗ and † indicate treatments with results that were significantly different from those of the control treatment with an added inoculum of the take-all fungus (G. graminis var. tritici). Use of different symbols indicates that treatments were significantly different from each other. Control treatments contained no bacterial inoculant. All data are means from eight replicate pots. 

^bObtained by measuring take-all-induced lesions of seminal roots as a percentage of total seminal root length. 

^cTotal water lost per pot over the last 14 days of a 28-day experiment. 

^dEach pot contained five plants. 

^eP value for root lesion analysis excluded control treatment with no added G. graminis var. tritici.
