Disease relevance of Helminthosporium

• Expression of the Totivirus Helminthosporium victoriae 190S virus RNA-dependent RNA polymerase from its downstream open reading frame in dicistronic constructs [1].
• SDS-PAGE of the 190S virus of Helminthosporium victoriae, using a discontinuous buffer system, revealed two major capsid polypeptides of mol. wt [2].
• Compound 1 inhibited the growth of Bacillus subtilis, Staphylococcusaureus, and Sarcina lutea with minimal inhibitory concentrations (MICs) of 25, 50, and 50 microg/mL, respectively, and the crop pathogenic fungus Helminthosporium sativum (MIC: 50 microg/mL) [3].

High impact information on Helminthosporium

• (ii) Pretreatment of rabbit skin cells with inhibitors of HDAC activity (e.g., sodium butyrate, Helminthosporium carbonum toxin, or trichostatin A) accelerated the expression of HSV-1(vCPc0) but not that of wild-type virus [4].
• The mode of translation and the genomic organization are similar to those of Helminthosporium victoriae 190S virus (Hv190SV; Huang, S., and Ghabrial, S. A. (1996). Proc. Natl. Acad. Sci. USA 93, 12541-12546) [5].
• He also showed 4+ positive skin prick responses to multiple trees, grasses, and weeds, Alternaria, Helminthosporium, dog, and histamine control and was 3+ positive to house-dust mites, Penicillium, Aspergillus, cat, and feather mix [6].
• Furthermore, Helminthosporium carbonum toxin (HC toxin), a structurally dissimilar inhibitor of histone deacetylase, mimicked the effect of butyrate [7].
• A majority of these organisms formed pergolide sulfoxide, and a Helminthosporium species was investigated in greater detail since it yielded significant amounts of pergolide sulfoxide [8].

Biological context of Helminthosporium

• The data so obtained have been used to define the preparatively useful limits of S-oxidation of phenyl alkyl sulfides and benzyl alkyl sulfides by biotransformation using Helminthosporium [9].

Associations of Helminthosporium with chemical compounds

• A PCR-based method to characterise and identify benzimidazole resistance in Helminthosporium solani [10].
• Biotransformation of organic sulfides--IV. Formation of chiral benzyl alkyl and phenyl alkyl sulfoxides by Helminthosporium species NRRL 4671 [9].
• From submerged cultures of the marine basidiomycete Halocyphina villosa we isolated siccayne (4-(2,4-dihydroxyphenyl)-2-methyl-1-buten-3-yne) (1), a metabolite first described from fermentations of the deuteromycete Helminthosporium siccans [11].
• 1. The biotransformations of triphenyl phosphite and of triphenyl-, tri-n.-butyl-, diethylphenyl-, and ethylmethylphenyl-phosphines by the fungi Mortierella isabellina ATCC 42613, Helminthosporium species NRRL 4671, and Aspergillus foetidus ATCC 10254, have been examined [12].
• Carbon dioxide fixation in Helminthosporium cynodontis [13].

Gene context of Helminthosporium

• This apparently is the first reported case of corneal perforation due to a mixed infection of Helminthosporium species and Mima polymorpha [14].
• In this study, direct comparisons are made between TA-FAB, conventional FAB, and electron impact ionization for the analysis of the Helminthosporium carbonum mycotoxins at the 1.5 micrograms level [15].
