This book presents the latest research results on plant genes controlling tolerance to abiotic stresses including heat, cold, drought, salt, nitrogen, metals, irradiation, and exogenous phytohormones. The authors report the expression profiles, function/roles in physiological pathways, and chromosomal locations of tolerance genes. The studies involve cytogenetics, genomics, proteomics, and bioinformatics. The information is critical for food security in an environment experiencing global climate changes. Therefore, this book provides a useful reference to students and professionals in plant sciences encompassing genetics, physiology, chemistry, and breeding.
Plants are constantly exposed to changing environmental conditions. Abiotic stresses cause adverse effects on plant growth, development, survival, and yield. It is essential to improve plant responses to such environmental conditions to achieve sustainable crop growth, development, and productivity. The activation of plant stress signaling mechanisms is crucial to address the adverse impacts of environmental factors on plant growth and productivity. Phytoprotectants, including signaling molecules, play crucial roles in the activation of plant physiological and molecular mechanisms to withstand the negative effects of abiotic stress on plants. Investigation of physiological, biochemical, and metabolic pathways associated with plant adaptation to abiotic stress will help identify the key players involved in plant abiotic stress tolerance mechanisms. The sensing, signaling, and gene regulatory mechanisms that help plants cope with abiotic stress must be fully explored.
The Republic of the Sudan was long the largest country in Africa and, according to the general consensus, also one of the least successful in many ways. This was not entirely its fault since it lay along the fault line between Muslim and Christian Africa and between the Nile Valley civilizations and African Sudanic cultures. This partly explains the long and bloody warfare waged by the Southerners to achieve independence, which they did in July 2011. So this hefty book actually covers not one but two states. This fourth edition of the Historical Dictionary of the Sudan does so, first, through a lengthy and detailed chronology tracing its relatively few successes and numerous failures. The introductory essay does an admirable job of putting it all in perspective. But the most informative part is the dictionary, with now over 700 entries for this fourth edition. They deal with important personalities, politics, the economy, society, culture, religion and inevitably the civil war. There are also appendixes and an extensive bibliography.

What is art and what is its role in a China that is changing at a dizzying speed? These questions lie at the heart of Chinese contemporary art. Subversive Strategies paves the way for the rebirth of a Chinese aesthetics adequate to the art whose sheer energy and imaginative power is subverting the ideas through which western and Chinese critics think about art. The first collection of essays by American and Chinese philosophers and art historians, Subversive Strategies begins by showing how the art reflects current crises and is working them out through bodies gendered and political. The essays raise the question of Chinese identity in a global world and note a blurring of the boundary between art and everyday life.
