1Two independent experiments were carried spanning 7 weeks.
2Two-week-old Arabidopsis Col-0 seedlings were transplanted into control soil or PICF7- or WCS417r- bacterized soil (9⋅107–2⋅108 cfu/g soil) previously autoclaved. Five weeks later, six to eight well-developed leaves were inoculated by applying 5-μl droplets of a conidial suspension of B. cinerea (1.7–7.5⋅105 conidia/ml half strength PDB). Plants were grown in growth chamber under controlled conditions.
