Fig. S1. Growth inhibition haloes generated by colonies of Pseudomonas fluorescens PICF7 (5 μl droplets, 108 cfu ml−1) grown on PDA plates previously inoculated with Pseudomonas savastanoi NCPPB 3335 (100 μl, 105 cfu ml−1). Plates were incubated at 25°C (A) and 28°C (B) during 72 h.


Fig. S2. Volume, fresh weight and density of knots developed on 1- (A) and 2-year-old (B) in vitro olive plants when Pseudomonas savastanoi NCPPB 3335 was inoculated in the presence (+PICF7) or the absence (−PICF7) of Pseudomonas fluorescens PICF7 at 92 days after inoculation. Error bars represent standard error. Mean values [n (tumours analysed) = 12, in 1-year-old plants, and n = 15, in 2-year-old plants] were not significantly different (P > 0.05) according to Student's t-test.


Fig. S3. Transversal section of representative knots produced by Pseudomonas savastanoi NCPPB 3335 when inoculated in the absence (A) or presence (B) of Pseudomonas fluorescens PICF7 (92 days after inoculation).
