Claviceps nigricans and Claviceps grohii: Their Alkaloids and Phylogenetic Placement
Journal of Natural Products, 2008Claviceps purpurea, C. grohii, C. zizaniae, C. cyperi, and C. nigricans are closely related ergot fungi and form a monophyletic clade inside the genus Claviceps. Analysis of alkaloid content in C. nigricans sclerotia using UPLC detected ergocristine (1), ergosine (2), alpha-ergocryptine (3), and ergocristam (4).

Biochemie und Physiologie der Pflanzen, 1978
Summary Preparations rich in chitin obtained from the cell walls of ergot fungi were studied by X-ray diffraction and IR-techniques. During the course of fermentation the yield of chitin was determined using a modified procedure according to R ide and D rysdale (1972).

Agroclavine hydroxylase of Claviceps purpurea
Biochimica et Biophysica Acta (BBA) - General Subjects, 1970Abstract The 60–80% ammonium sulfate fraction of Claviceps purpurea PRL 1980 catalyzed the conversion of agroclavine to elymoclavine. The reaction required NADPH. EDTA and cyanide inhibited the reaction. Agroclavine increased the rate of oxidation of NADPH. The increase in rate was 4.8 μmoles NADPH per h mg protein at 25° and pH 7.0.

Pyridine nucleotide biosynthesis in Claviceps
Archives of Biochemistry and Biophysics, 1973Abstract Claviceps purpurea grown on synthetic medium incorporated labeled [7- 14 ]nicotinic acid and [7- 14 C]nicotinamide into NaMN, des-NAD, NAD, and NADP. Label also appeared in NMN and N -methyl nicotinamide. The specific activities of NAD, NADP, and NMN are compatible with the operation of the Preiss-Handler pathway of NAD biosynthesis ...

The Infection of Rye Callus With Claviceps purpurea
Journal of the American Pharmaceutical Association (Scientific ed.), 1959Abstract The methods and results of inoculating callus cultures of rye( Secale cereale ) with ergot ( Claviceps purpurea ) are described. The fungus grows intercellularly and invades some cells, but does not produce alkaloids.

Biosynthesis of Phenylalanine and Tyrosine inClaviceps
Planta Medica, 1986Some enzymes of the terminal steps of phenylalanine and tyrosine biosyntheses were investigated in various alkaloid-forming ergot strains. All strains studied utilize both arogenate and phenylpyruvate as an intermediate in L-phenylalanine synthesis. L-Tyrosine is preferentially or exclusively synthesized via the arogenate pathway.

Enzymatic Methylation of Nicotinamide by Claviceps purpurea
Journal of Pharmaceutical Sciences, 1964Soluble supernatant fractions from two strains of Claviceps purpurea were tested for the presence of enzymes capable of methylating tryptamine, 5-hydroxytryptamine, tyramine, and nicotinamide. The latter compound was the only one of the substrates tested in which methylation took place.

Mycologia, 1911
While making an examination of a quantity of wild hay received from Beauce County, in the province of Quebec, Canada, in December, I909, I discovered that occasional spikes of a Carex, which constituted a large part of the hay, contained sclerotia of Claviceps.

Succinate dehydrogenase in the ergot fungus claviceps purpurea☆
Biochimica et Biophysica Acta, 1963Abstract 1. 1. A study of electron transport by cell extracts of the parasitic fungus Claviceps purpurea revealed a succinate dehydrogenase (EC 1.3.99.1) which appeared unique among mammalian and microbial succinate dehydrogenases so far studied in respect to ease of solubilization, solubility and stability, freedom from cytochrome contamination,
