Concerns about the effects of plant diseases on our lives are as relevant today. However, most people don’t think about plant diseases, and there is considerable concern among plant pathologists about this lack of awareness and wh...

A more detailed account of this work is being prepared for publication. 1 For some years investigations of the relations of environment to plant disease have been in progress at the University of Wisconsin (see Jones, L. R., "The Relation of Environment to Disease in Plants," Amer. J. Bot., 11, 601-609 (1924)). The present paper treats of a disease which affects only certain aerial parts of the...

Recent studies suggest that plant disease-resistance responses use multiple signaling pathways acting subsequent to pathogen recognition, and that phosphorylation cascades play a prominent role in the recognition and execution of foreign invaders.

Laser videodisc is a technology that is just beginning to be used to enhance agricultural and forestry education. We share our collective experience in producing a laser videodisc of plant disease images. This experience will be useful to other novices in the use of emerging technologies such as the laser videodisc to enhance their productivity and avoid costly errors and should be invaluable t...
