The Rhizobacterium Bacillus amyloliquefaciens MHR24 Has Biocontrol Ability Against Fungal Phytopathogens and Promotes Growth in Arabidopsis thaliana.

ABSTRACT: A novel rhizobacteria Bacillus was isolated from rhizosphere of soil associated with tomato (Solanum lycopersicum L.) under open field conditions. The Bacillus amyloliquefaciens strain MHR24 (MHR24) is a promising biocontrol agent against several fungal phytopathogens. In this research, MHR24 was characterized by an effective antagonistic ability against Alternaria alternata (Aa), Botrytis cinerea (Bc), Fusarium oxysporum F1 (F1), F. oxysporum F2 (F2), F. oxysporum R3 (F3), and Sclerotinia sclerotiorum (Sc). In particular, MHR24 showed a strong inhibition via airborne volatiles against Bc, F3, Aa, and F2 fungal strains. MHR24 also showed elevated saline stress tolerance at 1% and 25% to NaCl and KCl.
