Helminthosporium sacchari toxin and several lower molecular weight, nontoxic analogs were isolated from culture filtrates. Three isomers of the toxin (A, B, and C), each with four galactose units, were separated by high performance liquid chromatography. Isomer C had the highest and isomer A had the lowest toxicity to H. sacchari-susceptible sugarcane; resistant clones were not affected. Each toxin isomer was partially digested with a beta-galactofuranosidase and the resulting analogs (seven… Expand
Interconversions of aglycone and host-selective toxin from Helminthosporium sacchari
TLDR
The results suggest a metabolic route (aglycone → metabolite Y, → HS toxin → metabolites X and Y are lower molecular weight homologues of the toxin) for the biosynthesis of HS toxin. Expand
Cellular target of helminthosporium sacchari Toxin in sugarcane tissue
TLDR
Spindles from sugarcane tissue were challenged using labeled Helminthosporium (Bipolaris) sacchari toxin to determine the general effect on different organelles and structures, and a more efficient toxin labeling than previously reported was obtained. Expand
Chemical study of the blackleg fungus : metabolites, phytotoxins and phytoalexins
TLDR
Sixteen Thlaspi isolates of blackleg fungus originating from Saskatchewan were characterized on the basis of their secondary metabolite profiles, and it was determined that two of them were Polish type isolate and the remaining fourteen were weakly virulent type isolates. Expand
Host-selective toxins: agents of compatibility.
20 HSTs have been documented. In general, HSTs are deter? minants of host range or specificity in that plant species, varieties, or genotypes sensitive to an HST are those that are susceptible to theExpand
Unusual plant-growth regulators from microorganisms
TLDR
Fermentation products and their derivatives are logical candidates for the next generation of agrochemicals, and their structures, relative to biological activity, are discussed. Expand
Advances in Molecular Biology of Phytotoxin Production and Its Involvement in Plant Pathogenesis
TLDR
Phytotoxins produced by disease causing microorganisms are key factors in the development of number of destructive diseases of crop plants and are classified into either host-specific toxins or host nonspecific toxins. Expand
Determination of Host-Selective Toxins
TLDR
Since Hutchinson’s first toxigenic hypothesis of fungal plant disease, proposed in 1913, there have been many reports of phytotoxins isolated from culture filtrates of pathogens, and the evaluation of toxin in pathogenes is fluctuated from optimistic excitement to disappointment. Expand
Cochliobolus spp. and Their Host-Specific Toxins
TLDR
Two genera, Bipolaris and Curvularia, have been erected for the asexual (anamorph) stages of Cochliobolus, which is predominately heterothallic, although four homothallic species have been described. Expand
Host-selective toxins and avirulence determinants: what's in a name?
TLDR
This review summarizes some examples of the action of host-selective toxins to illustrate the similarity in responses with those to avirulence determinants. Expand

Isolation and characterization of host-selective toxin from Helminthosporium sacchari.
TLDR
Comparative data show that the toxin examined in this study is the same as the toxin described by Steiner and Strobel, and the previously proposed structure is incorrect. Expand
Conversion of Helminthosporium sacchari Toxin to Toxoids by beta-Galactofuranosidase from Helminthosporium.
TLDR
An enzyme with beta-galactofuranosidase activity was found in small amounts in the cultures of H. sacchari; the enzyme converted toxin to the toxoids in vitro, and more work is needed to determine the significance of enzyme production by these fungi. Expand
Biological Activity of the Isomeric Forms of Helminthosporium sacchari Toxin and of Homologs Produced in Culture.
TLDR
The effect of Helminthosporium sacchari (HS) toxin isomers and related, pathogen-produced compounds on dark CO(2) fixation in HS-susceptible sugar cane leaf slices was investigated and should prove a useful tool for understanding the mode of action of HS toxin. Expand
Toxic and protective effects of analogues of Helminthosporium sacchari toxin on sugarcane tissues
TLDR
Toxoids protect sugarcane tissues from toxin, as shown by use of the assay based on toxin-induced loss of electrolytes, and suggest that toxoids act as competitive inhibitors of HS toxin. Expand
