Virulence ofGibberella pulicarison Potato Tubers and Its Relationship to a Gene for Rishitin Metabolism

摘要: The ability of field strains Gibberella pulicaris (Fusarium sambucinum) to cause dry rot potato tubers is related their metabolize the phytoalexin rishitin. All highly virulent studied date have proven tolerant and able Preliminary genetic analysis one potato-pathogenic strain, R-6380, suggested that multiple loci might confer rishitin metabolism not all these are associated with virulence (A. E. Desjardins H. W. Gardner, Mol. Plant-Microbe Interact. 2:26-34) (...)
