Abstract |
Cytochalasin E (CE) is a secondary metabolite secreted by Rosellinia necatrix, caused by white root rot, and has toxicity to apple as a toxin during disease progress. This study was conducted to demonstrate the relationship between the production of CE and its pathogenicity. CE producing isolates and non-producing isolates of R. nectatrix were isolated from the mycerial mat of diseased roots and was detected on that using a TLC and HPLC analysis and in vivo pathogenicity test. CE non-producing isolates were not pathogenic to apple roots and not detected CE by TLC and HPLC analysis. It was shown that the production of CE was related to the pathogenicity of R. nectatrix. |
