Production of kanosamine by Bacillus cereus UW85.
Bacillus cereus UW85 produces two antibiotics that contribute to its ability to suppress certain plant diseases (L. Silo-Suh, B. Lethbridge, S. J. Raffel, H. He, J. Clardy, and J. Handelsman, Appl. Environ. Microbiol. 60:2023-2030, 1994). To enhance the understanding of disease suppression by UW85, we determined the chemical structure, regulation, and the target range of one of the antibiotics....
متن کاملDraft Genome Sequence of Biocontrol Agent Bacillus cereus UW85
Bacillus cereus UW85 was isolated from a root of a field-grown alfalfa plant from Arlington, WI, and identified for its ability to suppress damping off, a disease caused by Phytophthora megasperma f. sp. medicaginis on alfalfa. Here, we report the draft genome sequence of B. cereus UW85, obtained by a combination of Sanger and Illumina sequencing.
متن کاملinvestigation of antagonistic effect of bacillus subtilis on biological control of sugar beet damping - off disease
due to the high antagonistic activity of bacterium, bacillus subtilis (ehrenberg) cohn, three isolates (b.s.ham, 204 and 202) were selected and their efficacy were studied in control of sugar beetdamping–off caused by rhizoctonia solani , in in vitro and in vivo conditions. in dual culture on pda, all isolates of b.subtilis inhibited mycelial growth of r.solani. significantly, volatile metab...
متن کاملEffect of canavanine from alfalfa seeds on the population biology of bacillus cereus
Bacillus cereus UW85 suppresses diseases of alfalfa seedlings, although alfalfa seed exudate inhibits the growth of UW85 in culture (J. L. Milner, S. J. Raffel, B. J. Lethbridge, and J. Handelsman, Appl. Microbiol. Biotechnol. 43:685-691, 1995). In this study, we determined the chemical basis for and biological role of the inhibitory activity. All of the alfalfa germ plasm tested included seeds...
متن کاملCompatibility of systemic acquired resistance and microbial biocontrol for suppression of plant disease in a laboratory assay
Systemic acquired resistance (SARI and microbial biocontrol each hold promise as alternatives to pesticides for control of plant diseases. SAR and Bacillus cereus UW85, a microbial biocontrol agent, separately suppress seedling damping-off diseases caused by oomycete pathogens. The purposes of this study were to investigate how expression of SAR affected the efficacy of biocontrol by UW85 and i...
