Isolation, Purification, and Biological Activity of a Phytotoxin Produced by Stemphylium solani
Garlic leaf blight caused by Stemphylium solani is a serious disease in vegetable-growing areas of China (28). Symptoms of the disease start as small white spots (1 to 3 mm) enlarging to elongated purple necrotic lesions along the vein, followed by blighting of the leaf tips. Similar symptoms were produced by culture filtrates of S. solani, and a strong correlation was also found between garlic...
متن کاملSelection of phytotoxin producing rhizobacteria.
In order to select phytotoxin producing rhizobacteria to control weed plants, twenty five bacterial strains previously isolated from the rhizospheres of various plants were grown in a liquid medium and, after cell removal by centrifugation, the liquid phases were freeze-dried and the products were extracted with ethyl acetate/methanol. The extracts were concentrated to dryness under vacuum and ...
متن کاملSulfide as a soil phytotoxin—a review
In wetland soils and underwater sediments of marine, brackish and freshwater systems, the strong phytotoxin sulfide may accumulate as a result of microbial reduction of sulfate during anaerobiosis, its level depending on prevailing edaphic conditions. In this review, we compare an extensive body of literature on phytotoxic effects of this reduced sulfur compound in different ecosystem types, an...
متن کاملPhytotoxin Isolated from Liquid Cultures of Ceratocystis ulmi.
Phytotoxic material has been isolated from liquid cultures of Ceratocystis ulmi. One component of the material has been obtained in pure form and has proved to be a rather thermostable glycoprotein. This compound induced disease symptoms, similar to those produced by the fungus itself, in elm sprouits and trees.
متن کاملPhytotoxin Production in Bursaphelenchus xylophilus-Infected Pinus sylvestris.
Our findings suggest that i) phytotoxic materials can be isolated from Bursaphelenchus xylophilus-infected Scots pine, but not from noninfected pines; ii) the phytotoxins cause wilting of 45-day-old and 2-year-old pine seedlings in a dose and species dependent manner; iii) the phytotoxins are produced early in the infection, accumulate or increase with time, and may function to suppress water t...
