This second edition details protocols that analyze and explore gene regulatory networks (GRNs). Chapters guide readers through experimental techniques used to study genes and their regulatory interactions in plants, and computational approaches used for the integration of experimental data and bioinformatics-based predictions of regulatory interactions. 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. Authoritative and cutting-edge, Plant Gene Regulatory Networks: Methods and Protocols, Second Edition aims to be a useful and practical guide to new researchers and experts looking to expand their knowledge.
