Abstract:
Ht-toxin was extracted by singular or mixed organic solvents after solid and liquid culturing Helminthosporium turcicum in vitro, and pathogenic activity and toxicity of these extracts were assayed using root growth inhibition, isolated root cap cell death and isolated leaf soaking bioassays. Several best singular and mixed organic solvents have been screened for extracting Ht-toxin in vitro and this may lay foundation for its purification and structure analysis.
