Abstract
|
|
|
|
Two kinds of toxins were demonstrated in the culture filtrate of H. sativum, and were called ´M´ and ´D´ toxins. The lettuce bioassay indicated that D-toxin caused less root growth inhibition than M-toxin. Chemical analysis indicated that M-toxin was a very unusual small peptide. D-toxin was shown to have chemical characteristics similar to helminthosporal based on ultraviolet, proton nuclear magnetic resonance and mass spectra. D-toxin was composed of at least two isomers.
