Isolation and partial purification of a phytotoxin from Alternaria triticina


, : Isolation and partial purification of a phytotoxin from Alternaria triticina. Indian Journal of Experimental Biology 12(2): 195-198

The purified toxin isolated from culture filtrate inhibited root elongation of germinating wheat seeds at 1 mu g/ml, and also produced yellowing and wilting of wheat plants at 10 mu g/ml, similar to natural infection. Isolation of a similar toxin from infected plants points to its role during pathogenesis.
