Estimation of bacterial colonisation of wheat roots by Pseudomonas putida KT2440 and other spontaneous bacteria. (A) Number of colony forming units (CFU) per gram of root of wheat cultivar ‘Mercato’ at 14 and 42 days post inoculation. Green bars correspond to GFP-tagged P. putida KT2440 colonies and red bars to unidentified spontaneous growing bacteria. (B) Idem as (A) but for wheat cultivar ‘Avalon’. Shown are average values (n = 10; ±standard error).
