Elicitation: An Alternative Approach Towards Commercialization of Secondary Metabolite Production

Chapter

Abstract

Plants cells are considered to be excellent producers of a broad variety of chemical compounds. Many of these compounds are of high economic value such as various drugs, flavors, dyes, fragrances and insecticides. Unfortunately, the production of these compounds through the extraction of organs and seeds of whole plant is becoming more difficult since the natural growing areas of many of the species are being urbanized. Plant tissue culture not only constitutes a viable method to preserve the species, but also represent a constant and stable source of target alkaloids. Rapid strides in tissue culture techniques over the years have led to the possibility of growing plant cells as microorganisms in liquid media, for their utilization in the synthesis of a wide range of chemicals and pharmaceuticals, but commercial viability and economic feasibility are factors to be reckoned with in such industrial ventures. Various methods have been applied in order to enhance the productivity of such useful plant products; an efficient method has been the use of “elicitors”. Elicitors are chemicals or biological factors able to induce physiological and biochemical changes in the target cell. Stimulating effect of elicitors on secondary metabolite production is related to the interaction between elicitors and plant cells, elicitor signal transduction and defense response. Furthermore, the increased use of genetic tools and an emerging picture of the structure and regulation of pathways for secondary metabolism will provide the basis to move from a brute-force empirical approach for the optimization of production conditions.
