Book Description

Target Assays for Modern Herbicides and Related Phytotoxic Compounds is a laboratory guide that features 38 comprehensive contributions to determine and quantitate the inhibition activity of modern herbicides and related phytotoxic compounds at their targets. Using algal or higher-plant model species as well as cell-free enzymatic systems, assays are described for use with modern equipment typically found in a biochemical laboratory. Many details of the tests described in this volume are being published for the first time.

Assays discussed include carotenoid and chlorophyll biosynthesis and degradation, photosynthetic electron transport, amino acid biosynthesis, fatty acid formation, and cell division. Some model systems and related topics are also described. Each chapter represents an easy-to-read recipe with minimal theory including some key references for further reading. Original data from the experiments are provided, and most of the notable laboratories around the world are represented.

Target Assays for Modern Herbicides and Related Phytotoxic Compounds features updated methodology and procedures that will be a tremendous asset to plant biochemists; agriculture, plant protection, and weed control experts; agrochemical herbicide specialists in industry and government; and students in agricultural biochemistry and physiology.
