Quantitative molecular diagnostic assays of grain washes for Claviceps purpurea are correlated with visual determinations of ergot contamination. [PDF]
PLoS ONE, 2017 We examined the epiphytic microbiome of cereal grain using the universal barcode chaperonin-60 (cpn60). Microbial community profiling of seed washes containing DNA extracts prepared from field-grown cereal grain detected sequences from a fungus ...

Efficient genome editing in Claviceps purpurea using a CRISPR/Cas9 ribonucleoprotein method [PDF]
Synthetic and Systems Biotechnology, 2022 Claviceps purpurea produces many pharmacologically important ergot alkaloids (EAS), which are widely used to treat migraine and hypertension and to aid childbirth. Although an EAS biosynthetic cluster of C. purpurea has been discovered more than 20 years

The Epipolythiodiketopiperazine Gene Cluster in Claviceps purpurea: Dysfunctional Cytochrome P450 Enzyme Prevents Formation of the Previously Unknown Clapurines. [PDF]
PLoS ONE, 2016 Claviceps purpurea is an important food contaminant and well known for the production of the toxic ergot alkaloids. Apart from that, little is known about its secondary metabolism and not all toxic substances going along with the food contamination with ...

Comparative Ergot Alkaloid Elaboration by Selected Plectenchymatic Mycelia of Claviceps purpurea through Sequential Cycles of Axenic Culture and Plant Parasitism [PDF]
Biology, 2020 Ergot alkaloids have an established place in plant pathology and toxicology. As pharmaceuticals, their sourcing is via natural or managed agricultural occurrence of sclerotia of Claviceps purpurea (Fr.) Tul.

Sympatric divergence of the ergot fungus, Claviceps purpurea, populations infecting agricultural and nonagricultural grasses in North America [PDF]
Ecology and Evolution, 2021 The ergot diseases of agricultural and nonagricultural grasses are caused by the infection of Claviceps spp. (Hypocreales, Ascomycota) on florets, producing dark spur‐like sclerotia on spikes that are toxic to humans and animals, leading to detrimental ...

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.

UPDATED REVIEW ON EXTRACTION, ISOLATION AND QUANTITATIVE ESTIMATION OF ERGOT ALKALOIDS [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 2022 Ergot Alkaloids are potent α-blockers that cause direct smooth muscle contraction. They are products of fungi in the genus Claviceps. The most prominent member of this group is Claviceps purpurea (rye ergot fungus).
