This book presents a broad perspective on saponins as important natural products with a key role in plant defense. The presence of saponins has been reported in several plant species, and many types of saponins have been found to exhibit significant antifungal activities. In addition to their role in plant defense, saponins are of increasing interest for drug research, as they are active ingredients in several traditional medicines and hold potentially valuable pharmacological properties. In this book, the authors briefly introduce readers to saponin accumulation in various plant organs, with a specific focus on their structure classification and diversity. Readers will find detailed information on the saponin structure-activity relationship and saponins’ vital role in sustainable agriculture as a chemical barrier to pathogen attack. The latest techniques for isolating, identifying, and quantifying saponins are also discussed. In the closing chapter, the authors outline the recent metabolic engineering strategies applied to improve saponin glycosides production and their potential applications in plant disease resistance. This book and the companion volume Bioactive Molecules in Plant Defense: Signaling in Growth and Stress offer vital resources for all researchers and students interested in plant pathology, mycology and sustainable agriculture.
This book focuses on signaling molecules in plant defense, outlining some of the most important cellular and chemical plant defense strategies during periods of stress and growth. Written by leading experts, it covers topics such as the diversity of plant-growth-promoting fungi, the gene-to-metabolite network of plant-microbe interactions, modulation of plant cellular responses to stress, and how plant nutritional deficiency affects crop production. Together with the companion volume Bioactive Molecules in Plant Defense: Saponins, this book offers an essential source of information for postgraduate students and researchers interested in plant pathology, mycology and sustainable agriculture.
Useful throughout history for their medical as well as other benefits, plant-derived compounds have gained particular importance recently, due to environmental factors. The isolation and characterization of plant products, the identification of their role in the plant, and ways of synthesizing identical compounds or more potent analogues are covered. Also includes methods of culturing plant tissues and genetic engineering as a means of increasing the yield of desired substances from plants. Special emphasis is placed on plants previously unknown to Western scientists.
Plants have always been a source of nourishment and healing for living things. Their dual task of producing nutrients and medicines has played a key role in the evolution of herbivore and omnivore organisms. The so-called secondary metabolites are molecules with well-defined functional roles. These compounds are produced to defend plants from abiotic and biotic stresses. The complexity of the molecular structures produced by plants is only equal to their versatility and chemical diversity, while the harmonic intertwining of biosynthetic and metabolic pathways offers a perfect picture of the adaptive plasticity of plants to changing environmental conditions. This book is divided into three parts designed to provide the reader with a general overview, a biochemical and a biotechnological approach to plant bioactive molecules. The first part analyses the concepts of chemical diversity, sustainability and functional role of bioactive molecules, by exploring the sites of synthesis and accumulation, the plant defence strategies and the use of bioactive molecules as food supplements and as a source for natural products to fight diseases. The first part ends with the study of chemotaxonomy. The second part is dedicated to plant biochemistry, with the detailed description of the main biosynthetic pathways leading to the synthesis of phenols and flavonoids, terpenes, oxylipins and nitrogen-containing substances. The third and final part describes plant biotechnology and production of bioactive molecules with industrial processes, both in vivo and in vitro. Special attention is paid to cell and tissue cultures, roots and shoots cultures, technological aspects describing bioreactors, biofermenters and photobioreactors. The book concludes with a chapter describing the genetic engineering strategies for the production of plant bioactive molecules, facing with ethical problems, risks and benefits of using recombinant DNA in genetically modified organisms (GMOs) and the use of molecular pharming, with a general discussion on food safety.
The ascomycete Verticillium longisporum is an allodiploid hybrid adapted to infecting crucifers. Hybridization of A1 with D1, D2 and D3 formed three V. longisporum lineages. Some Necrosis and Ethylene Inducing Peptide 1(Nep 1)-Like proteins (NLPs) are cytotoxic in dicot plants and some induce plant defense responses. Phytoalexins are plant defense metabolites induced by pathogen infection that are toxic to microorganisms. We found that the genome of V. longisporum harbors 8 NLP genes which are similar to NLP genes of V. dahliae. The purified product of VlNLP1 was cytotoxic in Arabidopsis, B...

When introduced to the human body, bioactive metabolites produced by plants for self defense bind to particular biochemical targets, most notably to proteins involved in signaling by hormones and neurotransmitters. This, essentially, is the basis for the effects of herbal medicine. While herbal medicine preparations may act by complex synergistic interactions, molecular explanations of herbal medicine efficacy and side effects ultimately require definition of the biochemical targets of individual plant bioactive constituents. Biochemical Targets of Plant Bioactive Compounds is a comprehensive and user-friendly reference guide to biochemical targets of plant defensive compounds. With 500 pages of tables, it presents a mine of succinctly summarized information relating to bioactive compound structures, plant sources, biochemical targets and physiological effects that can be readily accessed via chemical compound, plant genus, plant common name and subject indexes. With introductory chapters providing reviews of the structural diversity of plant defensive compounds and biochemistry, this book is an invaluable reference for biomedical professionals in the fields of alternative/complementary medicine, natural product chemistry, toxicology, pharmacology, and botany.
