Abstract:
Plants produce a large number of anti-fungal materials. Many of these compounds are structural and are present in plants normally. The pathogen can cause disease that pass of the barrier of these compounds. On the other hand, there are compounds in plants that are inactive in the normal mode, this compounds was called phytoalexins. The phytoalexins are broad spectrum inhibitors and are chemically diverse with different characteristic types of particular plant species. Phytoanticipin distribution in plants often performed specifically and the concentration of these compounds in the outer cell layers of plant tissues were high. Studies on phytoanticipins are often done by focusing on the mutant plants. Phytoanticipins are divided in two groups, compounds with low and high molecular weight. Low molecular weight compounds include phenols and quinones, the unsaturated lactone, sulfur compounds, saponins, cyanogenic glycosides and terpenoids. High molecular weight compounds including tannins and proteins. In this study, it was studied the compounds plant defense against pathogen stress.
