Technical Abstract: The plant epidermis (the outer most layer of cells covering plants) is the part of a plant most exposed to the environment. Some plant species possess specialized epidermal cells called trichomes and root hairs protruding on the the surface of leaves, stems and/or roots. These cells are often involved in producing natural products with powerful biological activities, including antifungal, insecticidal and herbicidal properties. These compounds are thought to participate in the protection of plants against biotic challenges. This review discusses the production of natural pesticides by these amazing structures, as well as summarizes the practical significance of the existence of these special cells.
