Six isolates of Xcc and 24 isolates of Paenibacillus spp. were isolated from New Zealandgrown
brassica hosts or soil in 2008 (Table 1) (van Zijll de Jong, E., unpublished data). All
isolates were kept in the Smart Seeds collection at -80°C in Luria-Bertani broth (LB;
Sigma-Aldrich) amended with glycerol (25%).
