The time required for infectious tobacco necrosis virus (TNV) to pass through the epidermis of cowpea leaves after mechanical inoculation, depended on plant age and environmental temperature. At 22°C the passage time was about 2 h but at 32°C it was only 10 min. Water stress seemed to play a role in the transport of infectious virus into the mesophyll. It(More)
When cowpea mesophyll tissue with or without any epidermal layer was inoculated with tobacco necrosis virus (TNV), local necrotic lesions were produced. In epidermal strips isolated after inoculation of intact leaves local lesions were never observed. Homogenates of epidermal strips removed within 30 min after inoculation of the leaf with the cowpea strain(More)
