Book Description
This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere. The first volume principally treats families of the Early Angiosperms, Eudicots, Core Eudicots and Rosids, while the second concentrates on the Asterids. Presented in Volume 2 are microsections of the xylem and phloem of herbs, shrubs and trees of 1000 species and ca. 35 families of various life forms of the temperate zone along altitudinal gradients from the lowland at the Mediterranean coast to the alpine zone in Western Europe. Special attention is given to the very diverse family of Asteraceae. The global perspective of the findings is underlined by the analysis of 400 species from the Caucasus, the Rocky Mountains and Andes, the subtropical zone on the Canary Islands, the arid zones in the Sahara, in Eurasia, Arabia and Southwest North America, New Zealand and the boreal and arctic zones in Eurasia and Canada. The presence of annual rings in all life forms demonstrates that herbs and dwarf shrubs are an excellent tool for the reconstruction of annual biomass production and the interannual dynamic of plant associations. The common principle of the anatomical expression of secondary growth is a key factor in understanding evolution and adaptation processes in all life forms, from the 3 cm tall crepide pigmea (Crepis pygmaea) in the alpine zone to the 40 m tall ash (Fraxinus excelsior) in Central European riparian forests. The study opens vast fields of research for dendrochronology, wood anatomy, taxonomy and ecology.

Book Description
Ethnopharmacology and Biodiversity of Medicinal Plants provides a multitude of contemporary views on the diversity of medicinal plants, discussing both their traditional uses and therapeutic claims. This book emphasizes the importance of cataloging ethnomedical information as well as examining and preserving the diversity of traditional medicines. It also discusses the challenges present with limited access to modern medicine and the ways in which research can be conducted to enhance these modern practices. The book also explores the conservation procedures for endangered plant species and discusses their relevance to ethnopharmacology. Each chapter of this book relays the research of experts in the field who conducted research in diverse landscapes of India, providing a detailed account of the basic and applied approaches of ethnobotany and ethnopharmacology. The book reviews multiple processes pertaining to medicinal plants, such as collecting the traditional therapeutic values and validation methods. It also explores developments in the field such as the diversity and medicinal potential of unexplored plant species and applications in drug formulation to fight against anti-microbial resistance (AMR).

Book Description
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.

Book Description
Plant bioactive compounds are plant-based natural products that display a variety of pharmacological applications. These bioactive compounds are important as medicines, pigments and flavorings since most of the pharmaceutical industries are highly dependent on medicinal plants and their extraction. The types and concentrations of bioactive compounds produced by plants are determined by the species, genotype, physiology, developmental stage and environmental factors during growth, determining the physiological adaptive responses employed by various plant taxonomic groups in coping with the stress and defensive stimuli. In the past two decades there has been a renewed interest in the study of conventional aspects such as elicitors and biotic and abiotic stress factors that influence secondary metabolism during in vitro and in vivo growth of plants. the application of molecular biology tools and techniques are facilitating increased understanding of the signaling processes and pathways involved in the bioactive compounds production in subcellular, cellular, organ and whole plant systems during in vivo and in vitro growth, with application in the metabolic engineering of biosynthetic pathways intermediates. Biosynthesis and Manipulation of Bioactive compounds in Medicinal and Aromatic Plants provides a comprehensive introduction and review of the state-of-the-art biotechnological tools used in enhancement of bioactive compounds in medicinal and aromatic plants. Readers will find a systematic overview of techniques such as Omics, Crisper /Cas9 and RNAi to enhance plant bioactive contents including various in vitro techniques, hairy root culture and transgenic technology to enhance plant bioactive contents using plant tissue culture approaches. The chapters provide an overview of the role of induced mutation, biotic and abiotic stress to increase the bioactive contents in plants, plus the role of endophytes to enhance the contents of plant bioactive compounds and standard operating procedures using hydroponics system of cultivation for significant enhancement of bioactive compounds. This book serves as a single source for researchers working in plant secondary metabolites and the pharmaceutical industry.
