This second edition describes up-to-date methodological approaches, ranging from physiological assays to imaging and molecular techniques, to study a wide variety of plant responses to environmental cues. Chapters are divided into four sections detailing protocols to investigate key biological processes underlying plant environmental responses in the model organisms Arabidopsis thaliana and Physcomitrella patens as well as in different crop species. 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, Environmental Responses in Plants, Second Edition aims to be a foundation for future studies and to be a source of inspiration for new investigations in the field.
