Phytostimulation and Biocontrol by the Plant-Associated Bacillus amyloliquefaciens FZB42: An Update

  • Rainer BorrissEmail author
Part of the Environmental and Microbial Biotechnology book series (EMB)


Bacillus amyloliquefaciens FZB42, the type strain for representatives of the plant-associated subspecies plantarum, stimulates plant growth and suppresses soil-borne plant pathogens. The strain has been sequenced in 2007. The B. amyloliquefaciens FZB42 genome reveals an unexpected potential to produce secondary metabolites. In total, 11 gene clusters representing nearly 10% of the genome are devoted to synthesizing antimicrobial metabolites and/or to confer immunity against them. Ability to synthesize nonribosomally, the antibacterial polyketides macrolactin and difficidin and the antifungal lipopeptide bacillomycin D is an unique feature of the subspecies plantarum. However, according to latest research, most of the secondary metabolites are not expressed in plant rhizosphere suggesting that the antibiome expressed during the plant-associated state of PGPR Bacilli does not reflect the vast genetic arsenal devoted to the formation of secondary metabolites. There is now strong evidence that plant-associated Bacilli trigger pathways of induced systemic resistance, which protect plants against attacks of pathogenic microbes, viruses, and nematodes.


Bacillus amyloliquefaciens Macrolactin Antimicrobial–metabolites plantarum 



Many of the recent data, reported in this review, have been obtained in close collaboration with the Helmholtz Center in Munich in frame of the PATHCONTROL project, and the laboratory of Yuewen Gao, Nanjing Agricultural University, China, in frame of a Chinese Collaborative project, financially supported by the BMBF, the German Ministry of Education and Research. I thank especially Soumitra Paul Chowdhury, Anton Hartmann, Joachim Vater, Liming Wu, Xuewen Gao, and Ben Fan (Nanjing Forestry University) for their fruitful collaboration during the last years.
