This volume describes different 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. Environmental Responses in Plants: Methods and Protocols is divided into four sections: Tropisms, Photoperiodism and Circadian Rhythms, Abiotic Stress Responses, and Plant-Pathogen Interactions. The chapters in these sections include detailed protocols to investigate some of the many key biological processes underlying plant environmental responses, mostly in the model organism Arabidopsis thaliana, but also in Physcomitrella patens and in different crop species such as rice, potato, barley, or tomato. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.Authoritative and practical, Environmental Responses in Plants: Methods and Protocols, is a great resource for plant physiologists, biochemists, and cell and molecular scientists interested in this exciting and fast-growing research topic.
