In plant pathology

Cross protection is well known in plant pathology, where inoculation with one virus, for example, can give a highly specific protection against subsequent infections by that virus (Sequiera, 1983). More interestingly in...

Much attention has been devoted to study of the role of pectic enzymes in plant pathology. Two comprehensive reviews have appeared during the past ten years.9,10 Hence, only some of the fundamental aspects and some subsequent observations will be discussed here. 

Vector A circular, nonchromosomal DNA found in bacteria (called plasmid) that can self-replicate and is used to carry new genes into cells. In plant pathology, a vector is an organism capable of transmitting a pathogen from one host to another, such as plant-feeding insects that transmit viruses. 

A basic principle in plant pathology is that fungicides are used for crops that lack natural resistance to the fungus involved. Two notorious examples are Phytophthora infestans on potato and Venturia inaequalis on apple. ISfo farmer would go to the labor and expense to spray his potatoes or his apples if he could have plants that successfully fight off their fungi. This principle says further that the amount of fungicide needed or the frequency of application is inversely proportional to natural resistance.

Until recently, developments in plant pathology and chemistry have been out of synchrony. Field observations of plant pathogens and their etiology have been meticulously recorded as a distinct, thorough discipline. In contrast, the isolation and identification of natural products from... 

Since its introduction in medical research in 1971, various types of enzyme immunoassays have been developed (21) The double antibody sandwich ELISA (DAS-ELISA) introduced in plant pathology in 1976 (23) has become the major test system for plant indexing in the Netherlands This technique can be applied to a wide range of plant pathogens Figure 1 shows the principle for the complex antigen situation for detecting bacteria (23) ...
