Toxins are products of metabolic activity of live cells of plants, animals or microorganisms. Bacterial toxins especially play an important role in human, animal and plant pathology. They are often defined as primary virulence factors with great importance in development of various diseases. Many species of plant pathogenic bacteria produce toxins with various importance in plant pathology. So far, it has been confirmed that bacteria belonging to genus Pseudomonas, Xanthomonas, Clavibacter and Streptomyces, produce toxins that are important in pathogenesis. Pseudomonas species synthesize wide spec- trum of phytotoxic substances. These toxins mainly influence symptom development such as chlorosis, watersoaking, and necrosis. Therefore, they are considered important factors of bacterial virulence. However, microbicidal activity of some of those toxins can be used in control of other harmful microorganisms. Toxin production also can be a determinative characteristic for some Pseudomonas syringae strains or pathovars.
