Abstract
Essential oils (EOs) have been demonstrated as efficacious against
B. cinerea. However, the underpinning enzymatic and proteomic mechanism for
these inhibitory effects is not entirely clear. Thus, this study examined the effects of lemon (Le) and lemongrass
(Lg) EOs (individually and in combination) against B. cinerea based on enzymatic
and proteomic analyses. Proteomics data are available via ProteomeXchange with
identifier PXD038894. Both EOs (individually and in combination) displayed
abilities to induce scavenging as observed with the reduction of H2O2. Measured
malondialdehyde (MDA) and superoxide dismutase (SOD) activity were increased in
all EOs treated B. cinerea mycelia compared to the control. Ascorbate peroxidase
(APX) activity was highest in Lg treated B. cinerea (206% increase), followed by
combined (Le + Lg) treatment with 73% compared to the untreated control.
