| heal.abstract | Plant diseases are responsible for annual crop loss order of 12 percent worldwide and, although pathologists have long known what makes plants sick, only recently have significant advances been made with respect to the genetics and biochemistry of disease resistance in plants. Plants respond to attack by fungi and other pathogens by mobilizing a complex network of active defenses. Localized defenses in cells immediately surrounding the side of infection include strengthening of the cell wall through callose deposition and lignification, synthesis of antimicrobial phytoalexins, and induction of lytic enzymes that attack the invading pathogen. This combination of responses can be effective in preventing the spread of infection, but there is also evidence that plants are capable of responding with a more broadly based defense mechanism known as systemic acquired immunity (SAR). SAR involves the induction of a set of pathogenesis-related (PR) proteins that appear to help ward off secondary infections. In this sense, SAR appears to resemble the human response in principle. Once activated by an invading pathogen, the immune capacity is distributed throughout the plant. Both naturally occurring compounds like salicylic acid (SA) and synthetic compounds, like benzo (1,2,3) thiadiazole-7-carbothioic acid-S-methyl ester (BTH), can induce SAR. In this report, a number of elicitors were used against Botrytis cinerea on tomato plants, of which Lignosulfonate (LS) proofed positive. LS proved in many experiments to be a powerful tool for controlling plant diseases not only when used before the infection, but also after. It proofed to enhanced resistance not only against Botrytis cinerea on tomato and maize plants, but also against Phytophthora infestans on tomato and potato plants. Combined with low concentrations of fungicide, LS proved to be as effective as the standard treatment. Therefore, LS can be used to decrease the amount of fungicide and also to induce the side effects caused by this fungicide. However, the other elicitors in this report did not induce resistance towards Botrytis. This does not mean that they are not important signaling molecules for defense pathways. | el |
