Biocontrol Efficacy and Mechanisms of Bacillus velezensis AP6 Against Brown Rot in Yam by Fusarium solani

Yangtian Li; Bowen Tang; Jinchi Xie; et al. Journal of Fungi 2026. doi:10.3390/jof12050345

Other claims from this paper (10)

Intervention effect Strain AP6 strongly antagonised F. solani, with an inhibition rate of 60.2%.
Observation Strain AP6 showed broad-spectrum antagonistic activity.
Observation Strain AP6 can produce siderophores, amylase and protease.
Observation Strain AP6 can produce cellulase and form biofilms.
Observation Strain AP6 changed the hyphal morphology of F. solani, inhibited spore germination and reduced pathogen viability.

Intervention effect The lipopeptides exhibited no direct antibacterial activity in vitro.
Intervention effect Phenylalanine ammonia-lyase activity increased markedly after lipopeptide treatment, peaking at 36 h with a 5.7-fold increase.
Intervention effect Polyphenol oxidase activity increased markedly after lipopeptide treatment, peaking at 36 h with a 6.8-fold increase.
Intervention effect Lipopeptide treatment downregulated AOX1a and CAT2, modulating ROS homeostasis.
