Submergence

Water stagnation and submergence are major factors in rice growing. Water stagnation and submergence happen as a result of excessive rainfall or flash floods. The duration of submergence can last several weeks, and the level of water may be as high as 100 cm. This impacts rice yields. This book analyzes different aspects, viz., morphology, physiology, biochemistry and genetics, and reviews the suitability of different varieties for better sustainability and reduction of yield loss. It also reviews the different types of floods, and studies biological changes in indigenous and recently developed rice varieties. There are seven chapters: Introduction, History of floods, Diversity of submergence, Adoptive morphology, Physiological aspects, Molecular and genetic aspects, and Yield and yield-gaps. It is comprehensive with scientific dogma, findings and reasonings for students at universities and researchers.

In the face of the enormous destruction caused by the December 26, 2004 Indian Ocean tsunami event, it is necessary to utilize more effective means of tsunami mitigation to prevent such tragedies. Based on the experiences gathered in storm wave damping by using submerged structures, Agnieszka Strusinska examines the applicability of artificial reefs as an integrated part of a multi-defence line strategy for tsunami attenuation. In her study, she first discusses the results of laboratory experiments in order to identify the difference in the nonlinear interaction of storm and tsunami-like solitary waves with an impermeable sub¬mer¬ged structure of a finite width (including generation of wave breaking and wave fission). With this basic knowledge, the damping performance of an artificial reef under tsunami impact is determined as a ratio of wave transmission, wave reflection, and wave energy dissipation for varying reef geometries and incident wave conditions using a Boussinesq-type numerical model.

A fully revised review of the latest research in molecular basis of plant abiotic stress response and adaptation Abiotic stressors are non-living environmental stressors that can have a negative impact on a plants ability to grow and thrive in a given environment. Stressors can range from temperature stress (both extreme heat and extreme cold) water stress, aridity, salinity among others. This book explores the full gamut of plant abiotic stressors and plants molecular responses and adaptations to adverse environmental conditions. The new edition of Plant Abiotic Stress provides up-to-date coverage of the latest research advances in plant abiotic stress adaptation, with special emphasis on the associated and integrative aspects of physiology, signaling, and molecular-genetics. Since the last edition, major advances in whole genome analysis have revealed previously unknown linkages between genes, genomes, and phenotypes, and new biological and –omics approaches have elucidated previously unknown cellular mechanisms underlying stress tolerance. Chapters are organized by topic, but highlight processes that are integrative among diverse stress responses. As with the first edition, Plant Abiotic Stress will have broad appeal to scientists in fields of applied agriculture, ecology, plant sciences, and biology.
