Zeitschrift für Naturforschung B, 1970 Using a strain of Claviceps purpurea which produces under submerged conditions chanoclavine, ergometrine and mainly ergotoxine the biosynthesis of ergoline derivatives has been studied. DL-Tryptophan- (ring-2-14C) is specifically incorporated into the lysergic acid moiety of ergotoxine· alkaloids.

Biosynthesis of Ergotamine in Protoplasts of Claviceps purpurea [PDF]
Microbiology, 1980 Protoplasts of Claviceps purpurea (ATCC 20102) were prepared in 0.8 m-sucrose containing 10 mm-CaCl2 and 10 mm-MgCl2. Protoplasts could revert to the filamentous state but not after treatment with water. Most of the protoplasts (about 80%) were highly vacuolated and these were separated from the non-vacuolated protoplasts and cell debris on the basis ...

Plant Biotechnology Journal, Volume 23, Issue 12, Page 5778-5796, December 2025.ABSTRACT Botrytis cinerea, the necrotrophic fungus responsible for grey mould disease, is a major threat to global crop production. Control strategies mainly rely on chemical fungicides, but resistance development limits their long‐term effectiveness. This study introduces, for the first time in crop protection, the use of DNA aptamers as a novel and ...

Advanced Science, Volume 12, Issue 43, November 20, 2025.Appressoria are specialized penetration structures for many plant pathogenic fungi, demanding precise cell cycle control. This study unveils MoMtg1 as a transcriptional repressor of MoSwi6, orchestrating MoCYC1 expression during turgor‐driven cell cycle progression to enable appressorium‐mediated penetration. Moreover, a small‐molecule inhibitor ZS1619

Molecular Plant-Microbe Interactions, 2002 Claviceps purpurea is a common pathogen of a wide range of grasses and cereals that is able to establish a stable, balanced interaction with its host plant and is considered a biotroph. It does not form special penetration structures such as appressoria.

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.ABSTRACT Honeydew, a sugary excretion from sap‐feeding insects, significantly influences plant‐insect interactions. While extensive research has examined honeydew's composition, regulation, and role in insect‐plant relationships, its direct effects on plant physiology and health remain understudied.
