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 4675 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 of the compounds and on the plant species. Compound I was efficient for growth of seedling roots of soy, barley and wheat. Compound II and III were efficient for growth of seedling roots of soy and barley. Compound IV was efficient for growth of seedling roots of buckwheat. These compounds can be recommended for field study as plant growth stimulators.
