Morphological, Pathogenic and Toxigenic Variability in the Rice Sheath Rot Pathogen Sarocladium Oryzae [PDF]
Sheath rot is an emerging rice disease that leads to considerable yield losses. The main causal agent is the fungus Sarocladium oryzae. This pathogen is known to produce the toxins cerulenin and helvolic acid, but their role in pathogenicity has not been

Phytotoxins from Tithonia diversifolia [PDF]
Tithonia diversifolia (Mexican sunflower) is a dominant plant of the Asteraceae family, which suggests it produces allelochemicals that interfere with the development of surrounding plants. The study described herein was conducted to identify the compounds that have phytotoxic activity in T. diversifolia extracts.

Selection of phytotoxin producing rhizobacteria [PDF]
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.

Syringomycin, a Bacterial Phytotoxin, Closes Stomata [PDF]
The effects of the bacterial phytotoxin, syringomycin, on stomata were investigated using detached leaves of Xanthium strumarium and isolated epidermes of Vicia faba. Syringomycin is known to cause K(+) efflux in fungal and higher plant cells. Doses of syringomycin as low as 0.3 unit per square centimeter (about 0.88 pmole per square centimeter ...
