This volume provides updated technical approaches that have been developed to characterize monoterpene indole alkaloid metabolism in C. roseus from metabolite/gene product localization, alkaloid chemical synthesis, candidate gene prediction, transcription factor characterization up to functional genomic tools based on gene overexpression. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols.
