Effect of the Pathotoxin Victorin on the Pattern of Glucose Catabolism in Susceptible Oats. Carroll D.

Decreases in the ratio of ¹⁴CO₂ derived from glucose-6-¹⁴C to that from glucose-1-¹⁴C (the C₆/C₁ ratio) have been observed in a variety of diseased plant tissues. Victorin, the pathotoxin produced by Helminthosporium victoriae, causes a decrease in the C₆/C₁ ratio of susceptible oat leaves. This provides additional evidence that victorin induces metabolic alterations similar to those found in other diseased plants.
