Overview

Pathogenicity tests reveal Dickeya fangzhongdai causes 20% soft rot in bananas, indicating emerging biosafety risks.

Key Points

  • Banana plants infected with Dickeya fangzhongdai showed 20% incidence of soft rot across 33.33 hectares.
  • Pathogenicity tests confirmed 14 strains induce severe symptoms, with BG43 causing the most severe damage.
  • Genomic analysis revealed strain BG43 has >99% identity to known Dickeya fangzhongdai strains as confirmed by phylogenomic analysis.
  • The findings highlight the need for urgent surveillance and phytosanitary measures in banana production regions.
