| Popis: | Helminthosporium sacchari produces a toxin which is responsible for the symptoms of eyespot disease in Saccharum officinarum. A rapid and highly repeatable bioassay based on increase in conductivity of tissue leachates showed that the interaction of toxin with sugarcane obeys Michaelis-Menten hyperbolic saturation kinetics. There was no evidence for positive or negative cooperation interaction. Resistant and susceptible cultivars of sugar cane had distinctive conductivity characteristics. Co-cultures of H. sacchari and suspension cultures of sugarcane gave up to a 4,000-fold increase in toxin production. |
