Pallidopenillines: Polyketides from the Alga-Derived Fungus Penicillium thomii Maire KMM 4675 as Stimulators of the Initial Stages of Crop Plant Development

The pallidopenilline A (I), 1-acetylpallidopenilline A (II), 1-deacetylpallidopenilline B (III) and pallidopenilline C (IV) isolated from marine fungus Penicillium thomi Maire KMM 467 5 were examined for their ability to stimulate growth of seedling roots of buckwheat ( Fagopyrum esculentum Moench), soy { Glycine max (L.) Merr.}, barley ( Hordeum vulgare) and wheat ( Triticum aestivum L.). The stimulatory effects depend on the chemical structure...
