Bacillus subtilis XF-1 is a gram-positive, plant-associated bacterium that stimulates plant growth and produces secondary metabolites that suppress soil-borne plant pathogens. In particular, it is especially highly efficient at controlling the clubroot disease of cruciferous crops. Its 4,061,186-bp genome contains an estimated 3853 protein-coding sequences(More)
The fungal pathogen Cochliobolus carbonum (anamorph, Bipolaris zeicola) causes Northern Leaf Spot, leading to a ubiquitous and devastating foliar disease of corn in Yunnan Province, China. Asexual spores (conidia) play a major role in both epidemics and pathogenesis of Northern Leaf Spot, but the molecular mechanism of conidiation in C. carbonum has(More)
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)
