2.2 Dickeya solani and D. dianthicola strains used in plant assays
Five D. dianthicola strains (RNS11-47-1-1A, CFBP1888, CFBP2982, CFBP2015, MIE34) and five D. solani strains (3337 = RNS08-23-3-1A, IPO2222, RNS05-1-2A, Ds0432.1, PPO9019) were used to produce plant inoculation assays. The strains were chosen to be representative of the diversity of the populations, i.e. from different geographical locations, isolation years or host of collection (potato plants vs ornamentals, Table S2 ), and regarding phylogeny placement with neutral markers (Figure S1 ). Phylogeny analyses were conducted using MEGA7 (Kumar, Stecher, & Tamura, 2016). Bacterial strains were stored at -80°C in glycerol (25% vol/vol). They were cultivated in TY medium (tryptone 5 g.L-1; yeast extract 3 g.L-1) with or without agar (15 g.L-1) at 28°C.
