In an attempt to develop a biological control agent against mycotoxigenic Fusarium species, we isolated Bacillus amyloliquefaciens strain DA12 from soil and explored its antimicrobial activities. DA12 was active against the growth of mycotoxigenic F. asiaticum, F. graminearum, F. proliferatum, and F. verticillioides both in vitro and in planta (maize). Further screening using dual culture exten...
The trp gene cluster of Bacillus amyloliquefaciens was found to be structurally similar to that of the Enterobacteriaceae. The translation termination codon of the putative trpE gene and the initiation codon for the putative trpD gene overlap at the trpE-trpD junction, and a promoter for the putative trpC gene is suggested to exist. A promoter-probe vector of Bacillus subtilis, pFTB281, was con...
Sporulation is a survival strategy, adapted by bacterial cells in response to harsh environmental adversities. The adaptation potential differs between strains and the variations may arise from differences in gene regulation. Gene networks are a valuable way of studying such regulation processes and establishing associations between genes. We reconstructed and compared sporulation gene co-expre...
BACKGROUND The plant growth-promoting rhizobacteria (PGPR) strain Bacillus amyloliquefaciens SQR9, isolated from the cucumber rhizosphere, protects the host plant from pathogen invasion and promotes plant growth through efficient root colonization. The phytohormone indole-3-acetic acid (IAA) has been suggested to contribute to the plant-growth-promoting effect of Bacillus strains. The possible ...
Several Bacillus strains belonging to the B. subtilis/amyloliquefaciens group isolated from plant-pathogen-infested soil possess plant-growth-promoting activity [Krebs, B. et al. (1998) J Plant Dis Prot 105, 181-197]. Three out of the four strains investigated were identified as B. amyloliquefaciens and were able to degrade extracellular phytate (myo-inositol hexakisphosphate). The highest extr...
Bacillus amyloliquefaciens Q-426 with strong antifungal activity was isolated from compost samples in Dalian of China. Four kinds of diketopiperazines were extracted from the strain including cyclo (Pro-Phe) (cPP) which had both Dand L-isomers. Studies in this paper found that cPP production and antifungal activity were affected by environmental factors including incubation time, temperature, p...
Hybrid (1 -33 -4)-P-glucanases which contain an N-terminal region derived from the Bacillus amyloliquefaciens enzyme and a C-terminal region of the closely related B. macerans enzyme may exhibit a thermostability superior to both parental enzymes. A systematic series of hybrid enzymes were constructed in order to delineate the amino acid residues that affect protein stability. Hybrid enzymes wi...
