The pathogenic site of the C-toxin derived from Bipolaris maydis race C in maize (Zea mays)

摘要

Bipolaris maydis race C strain 523 (C523) induces severer leaf blight on cytoplasmic male sterility (CMS)-C maize than on normal (N) maize. Previously, a pathotoxin isolated from C523 (C-toxin) was shown to be responsible for the disease. To understand the basis of the Differential responses between CMS-C and N maizes to this fungus, protein synthesis in vitro by Mitochondria from N and CMS-C cytoplasms was monitored after their incubation in a solution Containing the toxin (0.3/100).
