Overview

Randomized trial tests pathogenicity of Fusarium liaoningense in Asarum heterotropoides, indicating a new disease threat in China.

Key Points

  • This study aims to identify and confirm the pathogenicity of Fusarium liaoningense on Asarum heterotropoides.
  • Field observation of leaf spots on Asarum heterotropoides in China.
  • Molecular identification using TEF-1α and RPB2 sequences and phylogenetic analysis.
  • Pathogenicity tests on healthy plants using spore suspension and observation of symptoms.
  • All inoculated plants developed symptoms consistent with field observations within five days.
  • The pathogen was successfully reisolated and confirmed, fulfilling Koch's postulates.
  • Fusarium liaoningense is reported for the first time as a pathogen on Asarum heterotropoides in China.
