Studies on the Host-Specific Pathotoxins Produced by Helminthosporium maydis, race T

抄録

Two host-specific pathotoxins, Band 1- and Band 2-toxins, were isolated from the toxin complex obtained from the culture broth and mycelial mat of Helminthosporium maydis, race T, the fungus causing Southern corn blight disease. Chemical and spectrometric studies showed them to be polyketo-polyhydroxy compounds with C₄₁ carbon chains. Band 2-toxin is identical to Band 1-toxin except that Band .2 toxin has an additional hydroxyl group in place of one of the keto-group of Band 1-toxin.
