A disk-diffusion method experiment assessed the impact of nanosilver on production of secondary metabolites (pigments) by the Fusarium culmorum fungus. Nanosilver colloidal particles in water have been obtained by the use of a method based on high voltage electric arcs between silver electrodes. The silver nanoparticles size in colloid ranged between 15 and 100 nm and 7, 35 and 70ppm concentration...
Pyrrolizidine alkaloids (PAs) are the class of secondary metabolites that evolved as a powerful tool in the plant defensive interactions against herbivores. The occurrence of PAs in the plant world is scattered in several unrelated botanic families with special abundance in Asteraceae, Boraginaceae and Fabaceae. Homospermidine synthase (HSS) was recognized as a key enzyme that catalyzes homospermidine...
Phenylpropanoids are a numerous group of the secondary metabolites. The pathway of phenolic biosynthesis is induced in plants under the treatment of various unfavorable factors. Phenylpropanoid compounds act twofold: they can be toxic for plant, inhibiting their growth and development, and, on the other side, they protect plants from stress effect. In the paper the most important phenolics, their...
Transformed roots in axenic culture would prove to be a good model for the study of the aspects of secondary metabolism. They are morphologically differentiated and have the advantage of high growth in the liquid standard media without growth regulators. Hairy root cultures can express root-specific pathways and have stable production of alkaloids, polyacetylenes, sesquiterpenes, naphthoquinones and...
