Bacillus subtilis XF-1 has been used as a biocontrol agent of clubroot disease of crucifers infected by Plasmodiophora brassicae, an obligate pathogen. In order to maximize the growth inhibition of the pathogen, random mutagenesis using N-methyl-N′-nitro-N-nitrosoguanidine was applied to strain XF-1. The efficacy of 226 selected mutants was assessed against(More)
Plasmodiophora brassicae is a Plasmodiophorid and obligate biotrophic protist in the eukaryotic kingdom of Rhizaria. It causes clubroot disease of cruciferous crops by producing resting spores that can survive in the soil for more than ten years. Although up to date there is no effective chemical control but now a strain of the bacterium Bacillus subtilis(More)
