Links between Genetic Groups, Indole Alkaloid Profiles and Ecology within the Grass-Parasitic Claviceps purpurea Species Complex [PDF]

Toxins, 2015
The grass parasitic fungus Claviceps purpurea sensu lato produces sclerotia with toxic indole alkaloids. It constitutes several genetic groups with divergent habitat preferences that recently were delimited into separate proposed species.

Cross-talk of the biotrophic pathogen Claviceps purpurea and its host Secale cereale [PDF]

BMC Genomics, 2017
Background The economically important Ergot fungus Claviceps purpurea is an interesting biotrophic model system because of its strict organ specificity (grass ovaries) and the lack of any detectable plant defense reactions.

Unveiling nonribosomal peptide synthetases from the ergot fungus Claviceps purpurea involved in the formation of diverse ergopeptines [PDF]

Acta Pharmaceutica Sinica B
Ergopeptines or their derivatives are widely used for treating neurodegenerative and cerebrovascular diseases. The nonribosomal peptide synthetase—d-lysergyl peptide synthetase A (LPSA) determines ergopeptine formation but the detailed mechanism remains ...

Biology, Genetics, and Management of Ergot (Claviceps spp.) in Rye, Sorghum, and Pearl Millet

Toxins, 2015
Ergot is a disease of cereals and grasses caused by fungi in the genus Claviceps. Of particular concern are Claviceps purpurea in temperate regions, C. africana in sorghum (worldwide), and C. fusiformis in pearl millet (Africa, Asia).

Monitoring and Managing of Ergot Alkaloids in Cereal Grains: A Comprehensive Analysis of Analytical Challenges, Sampling Uncertainty, and Processing for Food Safety. [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Mining Indole Alkaloid Synthesis Gene Clusters from Genomes of 53 Claviceps Strains Revealed Redundant Gene Copies and an Approximate Evolutionary Hourglass Model

Toxins, 2021
Ergot fungi (Claviceps spp.) are infamous for producing sclerotia containing a wide spectrum of ergot alkaloids (EA) toxic to humans and animals, making them nefarious villains in the agricultural and food industries, but also treasures for ...

Epichloë Endophyte-Promoted Seed Pathogen Increases Host Grass Resistance Against Insect Herbivory

Frontiers in Microbiology, 2022
Plants host taxonomically and functionally complex communities of microbes. However, ecological studies on plant–microbe interactions rarely address the role of multiple co-occurring plant-associated microbes.

Establishment and micropropagation of axenic in vitro cultures of salt marsh grasses within the genus <i>Sporobolus</i>. [PDF]

Appl Plant Sci
Abstract Premise Salt marshes in the North Atlantic United States are dominated by grasses from the genus Sporobolus, which are perennial C4 plants known for tolerating saline, anoxic, and flooded coastal sediments. Establishing in vitro cultures of Sporobolus species remains a major challenge due to frequent seed contamination from ergot and ...
