Detection effect toxins produced by some types of fungi isolated from medicinal plants

Medicinal plants accompany many fungi belonging to different groups, including different types of zygomycotina, ascomycotina, deuteromycotina and yeasts (yeasts). Some of these fungi accompany the plant during its growth in the field and others contaminate weeds during Harvest and storage process. The fungi that infect crops were divided by Christensen (1965) into three groups. The first group includes the field fungi, which infect agricultural crops before harvest, and includes species belonging to the genera Alternaria, Fusarium, Helminthosporium, and Cladosporium. The second group is known as storage fungi, and includes fungi that attack crops. agricultural crops during storage. It includes species of the genus Aspergillus and Penicillium, These fungi are characterized by the fact that most of them produce toxins (Mycotoxins), which cause diseases to humans and animals when consuming crops contaminated with them. The third group includes rot fungi (RootFungi) that grow on the remains of plant materials and include: Chaetomiumspp, Papulosporaspp, Fusarium graminearum and Sordaria spp and found that most of the toxin-producing fungi belong to storage fungi and a few of them belong to rotting fungi that have the ability to produce toxins.
