Overview

Randomized trial demonstrates Aflrpn4's role in controlling A. flavus growth and aflatoxin levels, implying new intervention strategies.

Key Points

  • This study aims to explore the role of the transcription factor Aflrpn4 in regulating Aspergillus flavus growth and aflatoxin production.
  • Constructed gene deletion and complementation strains of A. flavus.
  • Conducted phenotypic analysis comparing wild-type and ΔAflrpn4 strains under various conditions.
  • Performed storage simulation assays with peanut and maize kernels.
  • ΔAflrpn4 strain showed a 52% reduction in aflatoxin B1 content compared to wild-type.
  • In storage assays, ΔAflrpn4 exhibited lower colonization capacity and biomass.
  • Deletion inhibited growth by 70% under sodium and potassium stress, compromising cell membrane integrity.
