Isolated plant protoplasts can be induced to fuse with protoplasts from different species and, therefore, provide an ideal system for genetic modification and for use in plant breeding. Techniques for electrofusion of plant protoplasts have been developed relatively recently, and specialized apparatus is required, although this is now becoming more widely(More)
Plant tissue cultures are now well-recognized as valuable experimental systems for use in the study of host-pathogen interactions. These techniques have obvious major advantages for the examination of obligately biotrophic fungi and also those with a necrotrophic life style, and it is in these areas that much research effort has been concentrated (1).(More)
