This Research Topic is part of the Phenotyping at Plant and Cell Levels: The Quest for Tolerant Crop Development series: Phenotyping at Plant and Cell Levels: The Quest for Tolerant Crop Development This Research Topic aims at accelerating the discovery of crop varieties that are able to withstand environmental stresses, via the use of phenotyping approaches at the plant and cellular levels. Climate change is expected to have a drastic impact on agriculture, notably by impacting water availability, precipitations, temperatures, soil nutrients, and the incidence of diseases and pests. A better use of plant genetic resources and plant breeding are key to tackling this challenge from climate change and for food security. Many landraces and wild relatives of crops are conserved in seed and gene banks. These collections are potentially valuable for breeders, but are presently underexploited. Moreover, the contribution of the soil microbiome to enhance the performance of specific plant genotypes has been overlooked. The aim is to generate crops that are resistant against biotic stress or can tolerate abiotic stress without significant impact on their performance. Current studies in the field of sensor technologies and phenomics are mainly empirically based and do not link the phenotypic parameters to the molecular scale. Similarly, many molecular studies do not correlate their findings to the whole plant phenotype. The quantitative high throughput analysis of crop potential and behavior during stress is a form of Genotype x Environment interaction and is a major bottleneck. We urgently need to identify resilient genotypes and to understand the underlying mechanisms of this resilience. Phenotyping science is quickly developing to characterize plant behavior, it's dynamic dimensions, and to quantify features such as growth and stress resilience, which increasingly permit to link the phenotype to genetic control.

Drought is one of the most severe constraints to crop productivity worldwide, and thus it has become a major concern for global food security. Due to an increasing world population, droughts could lead to serious food shortages by 2050. The situation may worsen due to predicated climatic changes that may increase the frequency, duration and severity of droughts. Hence, there is an urgent need to improve our understanding of the complex mechanisms associated with drought tolerance and to develop modern crop varieties that are more resilient to drought. Identification of the genes responsible for drought tolerance in plants will contribute to our understanding of the molecular mechanisms that could enable crop plants to respond to drought. The discovery of novel drought related genes, the analysis of their expression patterns in response to drought, and determination of the functions these genes play in drought adaptation will provide a base to develop effective strategies to enhance the drought tolerance of crop plants. Plant breeding efforts to increase crop yields in dry environments have been slow to date mainly due to our poor understanding of the molecular and genetic mechanisms involved in how plants respond to drought. In addition, when it comes to combining favourable alleles, there are practical obstacles to developing superior high yielding genotypes fit for drought prone environments. Drought Tolerance in Plants, Vol 2: Molecular and Genetic Perspectives combines novel topical findings, regarding the major molecular and genetic events associated with drought tolerance, with contemporary crop improvement approaches. This volume is unique as it makes available for its readers not only extensive reports of existing facts and data, but also practical knowledge and overviews of state-of-the-art technologies, across the biological fields, from plant breeding using classical and molecular genetic information, to the modern omic technologies, that are now being used in drought tolerance research to breed drought-related traits into modern crop varieties. This book is useful for teachers and researchers in the fields of plant breeding, molecular biology and biotechnology.

Environmental stresses represent the most limiting factors for agricultural productivity worldwide. These stresses impact not only current crop species, they are also significant barriers to the introduction of crop plants into areas that are not currently being used for agriculture. Stresses associated with temperature, salinity and drought, singly or in combination, are likely to enhance the severity of problems to which plants will be exposed in the coming decades. The present book brings together contributions from many laboratories around the world to discuss and compare our current knowledge of the role stress genes play in plant stress tolerance. In addition, strategies are discussed to introduce these genes and the processes that they encode into economically important crops, and the effect this will have on plant productivity.

The turn of the last century, amid the excesses of the Gilded Age, variety became a key notion for Americans'a sign of national progress and development, reassurance that the modern nation would not fall into monotonous dullness or disorderly chaos. Carrie Tirado Bramen pursues this idea through the works of a wide range of regional and cosmopolitan writers, journalists, theologians, and politicians who rewrote the narrative of American exceptionalism through a celebration of variety. Exploring cultural and institutional spheres ranging from intra-urban walking tours in popular magazines to the 1893 World's Parliament of Religions in Chicago, she shows how the rhetoric of variety became naturalized and nationalized as quintessentially American and inherently democratic. By focusing on the uses of the term in the work of William James, Anna Julia Cooper, W. E. B. Du Bois, Hamlin Garland, and Wong Chin Foo, among many others, Bramen reveals how the perceived innocence and goodness of variety were used to construct contradictory and mutually exclusive visions of modern Americanism. Bramen's innovation is to look at the debates of a century ago that established diversity as the distinctive feature of U.S. culture. In the late-nineteenth-century conception, which emphasized the openness of variety while at the same time acknowledging its limits, she finds a useful corrective to the contemporary tendency to celebrate the United States as a postmodern melange or a carnivalesque utopia of hybridity and difference. Table of Contents: Introduction: Americanizing Variety I. The Ideological Formation of Pluralism 1. William James and the Modern Federal Republic 2. Identity Culture and Cosmopolitanism II. The Aesthetics of Diversity 3. The Uneven Development of American Regionalism 4. The Urban Picturesque and Americanization III. Heterogeneous Unions 5. Biracial Fictions and the Mendelist Allegory 6. East Meets West at the World's Parliament of Religions Afterword: In Defense of Partiality Notes Works Cited Acknowledgments Index Reviews of this book: [Bramen] brings dogged research and steady focus to [a] central ambiguity in the American ethos...Her study delivers several powerful messages even plain-talking people can understand. For one, Bramen shows that issues of ethnic diversity and variety, far from being epiphenomena of the last few decades, course through our history and spotlight the ambiguities in what it means to be an American...The Uses of Variety boasts gems...of past cultural history that remind us these are perennial issues...[Bramen's] penetrating expedition through the nuances of America's breast-beating about 'diversity within unity' concentrates the mind. Out of many examples comes an important book: a flinty challenge to intellectual complacency about ourselves. --Carlin Romano, Philadelphia Inquirer The Uses of Variety is a significant addition to and revision of a century of American pragmatist thinking about difference. Bramen brings new conceptual tools to bear on the history of multicultural thought and literature and thereby avoids the common pitfalls to produce an important survey and synthesis. --Tom Lutz, author of American Nervousness, 1903: An Anecdotal History and editor of These 'Colored' United States: African American Essays from the 1920s Carrie Bramen offers a compelling, intellectually rigorous history of the protean idea of pluralism, a concept that has been embraced heartily by both liberals and conservatives as essential in defining American identity. Situating pluralism in philosophical, psychological, aesthetic, and political contexts, Bramen brings a fresh perspective to illuminating the meaning of the term for late Victorian America and, significantly, its legacy for us today. --Linda Simon, author of Genuine Reality: A Life of William James Taking William James's 'pluralistic universe' as a starting point, The Uses of Variety takes us through regions, ghettos, religious congresses, and a range of theoretical, philosophical, and literary works to explore the multiple and often conflicting constructions of 'variety' in the context of turn-of-the-century U.S. nationalism and cosmopolitanism. Carrie Tirado Bramen brings together a broad spectrum of historical events and cultural theories in which variety variously expressed, contained, and shaped an increasing diversity that was perceived as threatening national coherence. This insightful, thoroughly researched, and timely work will be indispensable for scholars interested in U.S. nationalism, modernism, cosmopolitanism, and multiculturalism. --Priscilla Wald, author of Constituting Americans: Cultural Anxiety and Narrative Form
