Years ago a review on ergot alkaloids (EA) appeared with the title: “The biosynthesis of ergot alkaloids; the story of the unexpected” (Floss, 1980). I don’t believe that any other title could be more appropriate since the entire history of EA research, from the discovery of ergotamine almost a century ago until the present, has truly been the history of the unexpected. The beginning of modern ...
Morphological characteristics of hyphal interaction between Grifola umbellata (Pers. Ex Fr.) Pilat and its companion fungus which related to sclerotia formation from hyphae were investigated by external observations, light microscopy and transmission electron microscopy (TEM). External observations showed that a dense antagonism line was formed by both G. umbellata and companion fungus after th...
The addition of organic residues to soil is an option to control some soil-borne diseases. Benzaldehyde and powders of kudzu (Pueraria lobata), velvetbean (Mucuna deeringiana), and pine-bark (Pinus elliottii and P. taeda) added to soil could reduce certain soilborne diseases. This study evaluated the effects of benzaldehyde and the dried powders of kudzu, velvetbean, and pine-bark as soil amend...
The objective of the research was to understand diversity Rhizoctonia solani in potato crops Nariño. Tubers with sclerotia were collected from farms municipalities Pasto, Ipiales, Tuquerres and Ospina. In a laboratory, strains grouped categories, selecting 30 for morphological pathogenic studies. an PDA medium, daily mycelia growth rate (DMGR), pigmentation, texture, pattern (GP) characteristic...
Background: The prevailing methods for the genomic DNA extraction of Sclerotium rolfsii from its mycelium mat is often time consuming and yields poor quality quantity owing to presence outrageous magnitude mucilage polysaccharides. Methods: A new fast track method isolation resting structure (sclerotia) S. by modifying CTAB deprived supplementation proteinase K has been standardized. Result: pr...
Clonostachys rosea f. catenulata is a promising biocontrol agent against many fungal plant pathogens. To identify mycoparasitism-related genes from C. rosea f. catenulata, a suppression subtractive hybridization (SSH) cDNA library of C. rosea f. catenulata HL-1-1 that parasitizes the sclerotia of S. sclerotiorum was constructed. 502 clones were sequenced randomly, and thereby 472 expressed sequ...
Bacteria, isolated from canola and soybean plants, produced antifungal organic volatile compounds. These compounds inhibited sclerotia and ascospore germination, and mycelial growth of Sclerotinia sclerotiorum, in vitro and in soil tests. Ascospore germination in cavity slides was inhibited 54–90% by the volatile producers. When mycelial plugs or the sclerotia, exposed to these volatiles, were ...
An antiserum specific for the globular domain of the bovine very lysine-rich histone subfraction H1(0) cross-reacted with a single protein band in the chromosomal proteins isolated from microplasmodia of the true slime mold Physarum polycephalum. Its amino acid composition was characteristic of a very lysine-rich histone which supported its identification as Physarum H1(0). Unlike Physarum H1(0...
