Investigating Bacillus amyloliquefaciens VFS2 for Vicia faba-fusarium wilt biocontrol and plant growth promotion under osmotic stress.

ABSTRACT:

Background

A dual assault from fungal infections and abiotic stress factors such as drought and salinity increasingly threatens fava bean production. These adverse conditions not only reduce crop yield and quality but also create a more conducive environment for fungal pathogens to thrive. In this study, we aim to investigate the potential of Bacillus amyloliquefaciens strain VFS2 for the biocontrol of Vicia faba-Fusarium wilt under drought and salt stress.

Results

The in vitro growth and sporulation of B. amyloliquefaciens VFS2 increased under salt and drought conditions (NaCl 0-200 mM and PEG6000 0-20%) in comparison to the unstressed control. The antifungal activity of VFS2 was screened against a broad-spectrum of V. faba-phytopathogenic fungi from the genera Fusarium, Bo
