Abiotic elicitors: A tool for enhanced production of secondary metabolites in tropical plants

Anna Langmaierová

Bachelor's thesis

Abstract:

Secondary metabolites are chemical compounds produced by plants as a reaction for stresses. They are synthetized from primary metabolites and ensure survivabilty of plants. Stress initiators, known as elicitors, are used since the second half of 20th century to enhance production of secondary metabolites. Elicitors are divided according to their nature into abiotic and biotic. The aim of this thesis is to introduce abiotic elicitors that are currently used in the production of secondary metabolites and to specifically focus on their production in tropical plants. Recent literature on this topic is introduced in this work. Tropical and subtropical plants are valuable resources of many secondary mentabolites. Their elicitacion is mostly provided by methyl jasmonate and salicylic acid. The most successful acquisition takes place through hairy root and cell suspension cultures. The most widely used plant families for their metabolites are Solanaceae, Lamiaceae, Plantaginaceae, Fabaceae and Vitaceae. Secondary metabolites obtained from these families are scopolamine, tanshinone, bacoside, reservatrol, glycyrrhizine acid and anthocyanin. They are mostly used in medicine and food industry.
