Overview

Randomized trial demonstrates Bacillus velezensis XG2 promotes growth and controls root rot in Angelica sinensis, highlighting its potential as a bioinoculant.

Key Points

  • This research aims to characterize Bacillus velezensis XG2 and evaluate its effects on plant growth, secondary metabolites, and biocontrol against root rot.
  • Isolated Bacillus velezensis XG2 from Angelica sinensis rhizosphere and confirmed identity via 16S rRNA and whole-genome sequencing.
  • Assessed plant growth parameters, antioxidant activities, and metabolite profiles using UPLC–MS and confocal microscopy.
  • Conducted dual-culture assays to evaluate antifungal activity against root rot pathogens.
  • Seed germination and plant height improved by 17.27% and shoot biomass increased by 59.14%.
  • Enhanced antioxidant enzyme activities observed: peroxidase (POD) increased by 77.20%, and catalase (CAT) increased by 102.39%.
  • Bacillus velezensis XG2 inhibited Mucor circinelloides by 38.38% and Fusarium tricinctum by 46.25%.
