Research uncovers Bacillus velezensis BV25's biocontrol and growth-promoting effects in tomatoes, suggesting sustainable solutions for Fusarium wilt management.
Key Points
This research aims to explore the biocontrol and growth-promoting mechanisms of Bacillus velezensis BV25 against tomato Fusarium wilt.
Conducted in vitro assays to assess FOL growth inhibition by BV25 and its extracts.
Performed greenhouse trials measuring the effects of BV25 fermentation broth on plant health and disease severity.
Analyzed defense enzyme activities in plants treated with BV25.
Executed complete genome sequencing of B. velezensis BV25 and performed ANI analysis to confirm species designation.
Identified secondary metabolite biosynthetic gene clusters and genes related to plant growth promotion.
Bacillus velezensis BV25 significantly inhibited Fusarium oxysporum growth in vitro.
The efficacy of BV25 extracts was found to be dose-dependent.
In greenhouse trials, BV25 reduced disease severity and improved plant growth even without the pathogen.
