Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Plants shield against microbes using structural defenses, antimicrobial compounds and secondary metabolites. Most plants have impermeable obstacles, such as waxy cuticles, or morphological adaptive transformations like thorns, which retard the pathogen's progression into plant tissues and prevent the release of deleterious substances such as enzymes for the degradation of walls or toxins. If a pest crosses the barriers of a plant, it is usually confronted with biochemical weapons including, but not limited to, secondary metabolites with antimicrobial ability.
