Tropisms, the defined vectorial stimuli, such as gravity, light, touch, humidity gradients, ions, oxygen, and temperature, which provide guidance for plant organ growth, is a rapidly growing and changing field. The last few years have witnessed a true renaissance in the analysis of tropisms. As such the conception of tropisms has changed from being seen as a group of simple laboratory curiosities to their recognition as important tools/phenotypes with which to decipher basic cell biological processes that are essential to plant growth and development. Plant Tropisms will provide a comprehensive, yet integrated volume of the current state of knowledge on the molecular and cell biological processes that govern plant tropisms.

This text explores the means, processes and mechanisms by which plants change the orientation and juxtapositions of various organs in order to optimize their harvest of energy, and examines the major stumuli which provokes such responses. These interactions are re-described for higher plants through to ferns, fungi and algae, and the text constantly emphasizes the functional significance of particular growth movements to plants in their natural surroundings.

Nathalie Sarraute's stunning debut—vignettes of "inner movements"—foreshadowed the rise of the nouveau roman. Hailed as a masterpiece by Jean Genet, Marguerite Duras, and Jean-Paul Sartre, Tropisms is considered one of the defining texts of the nouveau roman movement. Nathalie Sarraute has defined her work as the “movements that are hidden under the commonplace, harmless instances of our everyday lives.” Like figures in a grainy photograph, Sarraute’s characters are blurred and shadowy, while her narrative never develops beyond a stressed moment. Instead, Sarraute brilliantly finds and elaborates subtle details—when a relationship changes, when we fall slightly deeper into love, or when something innocent tilts to the smallest degree toward suspicion.

This updated and expanded edition explores key methodologies to study the fascinating phenomenon of how plants readjust their growth toward gravity. In addition to the protocols delivering broad applications for gaining insight into other plant physiological processes, this new volume also focuses on techniques involving plants in space or the use of microgravity analogs to study plant biological phenomenon. Written for the highly successful Methods in Molecular Biology series, 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 cutting-edge, Plant Gravitropism: Methods and Protocols, Second Edition serves as an ideal guide for researchers studying the cellular, molecular, and biochemical networks that plants use to translate environmental stimuli into a growth response.
