Dynamic Model of Virus Transmission in Plants
In the study of viral diseases in plants, the immune response of the plant plays a basic role. In this paper, a mathematical model based on differential equations system with time delay for the immune response of the plant is introduced. As follows, the dynamical behavior of the model in equilibrium points is investigated. At the end, a plant in two different modes, organic and non- organic is ...
متن کاملCytological Studies on Virus Diseases Op Solanaceous Plants '
Microscopical examinations of the tissues of mosaic-diseased plants have been made by numerous investigators since the earliest recognition of diseases of the plant virus group. With a few exceptions, these investigations have been confined to the study of a single virus disease upon a single species of host. It has now, however, come to be recognized that there are a number of different virus ...
متن کاملIdentification and Assessment of Fungal Diseases of Major Medicinal Plants
Medicinal plants are infected by fungal diseases. A four years survey indicated that, there are various fungal infections in roots and shoots of several medicinal plants that grown in Isfahan. Lavender (Lavandula angustifolia), rosemarry (Rosmarinus officinalis) and viper’s bugloss (Borago officinalis) plants were infected by Fusarium oxysporum and F. solani on roots, showing wilting and eventu...
متن کاملPopulation genetics of fungal diseases of plants.
Although parasitism is one of the most common lifestyles among eukaryotes, population genetics on parasites lag for behind those on free-living organisms. Yet, the advent of molecular markers offers great tools for studying important processes, such as dispersal, mating systems, adaptation to host and speciation. Here we highlight some studies that used molecular markers to address questions ab...
