Melanin protects the cell nucleus from the destructive effects of UV radiation Langerhans cells: arise from the bone marrow and migrate to the epidermis and other areas of the body containing stratified squamous epithelial tissue. Merkel cells: present in small numbers at the epidermal-dermal junction. Associated with a disc-like ending of a sensory nerve fiber‚ called a Merkel disc‚ which functions as a sensory receptor.

Initially‚ infected tissue is water soaked but becomes necrotic (brown or black) in a few days. Often the lesions are surrounded by a halo of light green tissue. Spores appear as white velvety growth at the edge of the lesions‚ primarily at the underside of the leaf. It is this white growth that distinguishes Phytophthora leaf blight from
