  • With the depletion of oil resources as well as the negative environmental impact of fossil fuels, there is much interest in alternative energy sources. Focusing on some of the most important alternate energy sources for the foreseeable future, the Handbook of Plant-Based Biofuels provides state-of-the-art information on the status of the production of biofuels, in particular, bioethanol and biodiesel. After profiling plant-based biofuels, the book gives an overview of the production of biofuels from biomass materials by thermochemical and biochemical methods.

  • Phytochemistry is a broad area, generally termed ‘‘plant chemistry.’’ Investigations in the field of phytochemistry are important for numerous research disciplines, such as plant physiology, plant biochemistry, chemosystematics (which is often referred to as chemotaxonomy), plant biotechnology, and pharmacognosy. Plant physiology focuses on the life processes occurring in plants. Especially important are the investigations on the influence of various external factors, such as ultraviolet–visible (UV–Vis) radiation, temperature, the nature of soil, the climate, etc.

  • arranged according to alphabetical order. Names of scientists and/or family names are in all capital letters. However, when used adjectively (e.g., Mendelian) or as a unit of measure (e.g., Ångström), only the first letter is capitalized. Explanations to a given term may be more or less extensive. Several definitions have simply been separated by a semicolon. Terms that are either very general in nature or self-explanatory have been avoided. Alternate names of terms have been given within the definition.

  • When the price of Ginseng advanced some years ago hundreds engaged in the business who knew little or nothing of farming, plant raising and horticulture. That they largely failed is not to be wondered at. Later many began in a small way and succeeded. Many of these were farmers and gardeners. Others were men who had hunted, trapped and gathered "seng" from boyhood. They therefore knew something of the peculiarities of Ginseng. It is from the experience of these men that this work is largely made up--writings of those who are in the business.

  • Early interest in selenium by nutritionists concerned its high concentration in certain range plants and the consequent toxicosis in animals that grazed those plants. More recently, the essential nature of selenium has become the center of attention, and this element is now known to be required by laboratory animals, food animals (including fish), and humans. Its role as an integral feature of glutathione peroxidase has been established, and other possible functions are under active investigation.

  • from the Latin cella, meaning storeroom or chamber. It was first used in biology in 1665 by the English botanist Robert Hooke to describe the individual units of the honeycomb-like structure he observed in cork under a compound microscope. The “cells” Hooke observed were actually the empty lumens of dead cells surrounded by cell walls, but the term is an apt one because cells are the basic building blocks that define plant structure. This book will emphasize the physi

  • PLANT CELLS, UNLIKE ANIMAL CELLS, are surrounded by a relatively thin but mechanically strong cell wall. This wall consists of a complex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. Plant cell walls also contain structural proteins, enzymes, phenolic polymers, and other materials that modify the wall’s physical and chemical characteristics.

  • Genetic diversity is the fundamental source of biodiversity. In 1989, the World Wildlife Fund defined biodiversity as “the richness of life on Earth – millions of plants, animals and microorganisms, including the genes which they carry, and complex ecosystems that create the environment”. Currently, the issue of maintaining genetic diversity as a component of the conservation of biodiversity has been accepted at an international level. FAO has included the issue of conservation, evaluation, and the use of animal genetic resources in its fields of interest since the 1970s.
