Book excerpt: In Plant Gene Transfer and Expression Protocols, leading experts present the latest step-by-step recipes for introducing genes into model and agricultural plants and for studying gene activity using reporter enzyme assays, RNA techniques, and immunological methods. The book contains not only a complete collection of mainstream methods, but also methods for studying gene expression and genetic manipulation in chloroplasts and mitochondria. There are also methods for introducing and analyzing plant genes in Xenopus and heterologous yeast hosts. Plant Gene Transfer and Expression Protocols is an indispensable tool for scientists working in both fundamental (biochemical, physiological, and genetic) and applied aspects of plant biotechnology, plant breeding, agriculture, and horticulture. It provides concise practical help that produces the desired results even for beginners and opens the doors to new research possibilities.
