The world’s population presently experiences a period of unprecedented growth, increasing the need to further intensify the agricultural production (Garnett et al.2013). At the same time, recent climate trends and model predictions suggest shifting temperature, precipitation and circulation patterns on global and regional scales (Shepherd 2014). In this context, the risk of temporal or unseasonal drought is increasing in many regions worldwide (Pachauri et al. 2014). Agriculture accounts for about 75 % of human water use (Wallace 2000). However, the availability of water is the most limiting abiotic factor for plant production (Boyer 1996). Therefore, agricultural production and food security are highly susceptible to increased incidences of drought. Improving the water-use efficiency (WUE) of crop plants and cropping systems is therefore an important strategy to face the current challenges of global change (Pinstrup-Andersen et al. 1999).

The world’s population reached 7.3 billion in 2015 and according to the United Nations, the world’s population will continue to grow by 1.18 % per year, projected to reach 8.5 billion in 2030 and 9.7 billion in 2050 (United Nations, 2015). Consequently, global demand for food is steadily rising and exerts a pressure on the need for more efficient crop production. However, efficient crop production is hampered by biotic and abiotic stress factors, such as drought. Drought poses the most important limitation to crop productivity in the world (Lauer et al. 2012) and increases in the frequency and intensity of drought events are predicted (Pachauri and Meyer 2014).

Changing Climate and Resource Use Efficiency in Plants reviews the efficiencies for resource use by crop plants under different climatic conditions. This book focuses on the challenges and potential remediation methods for a variety of resource factors. Chapters deal with the effects of different climatic conditions on agriculture, radiation use efficiency under various climatic conditions, the efficiency of water and its impact on harvest production under restricted soil moisture conditions, nitrogen and phosphorus use efficiency, nitrogen use efficiency in different environmental conditions under the influence of climate change, and various aspects of improving phosphorus use efficiency. The book provides guidance for researchers engaged in plant science studies, particularly Plant/Crop Physiology, Agronomy, Plant Breeding and Molecular Breeding. In addition, it provides valuable insights for policymakers, administrators, plant-based companies and agribusiness companies. Explores climatic effects on agriculture through radiation, water, nitrogen, and phosphorus-use efficiency Guides the planning and research of, and recommendations for, fertilizer application for different crops under various climatic conditions Discusses efficiency improvements for plant and molecular breeders seeking to maximize resource use

Plants cope with drought stress conditions by adjusting transpiration and simultaneously optimizing their carbon assimilation rates. Continuous stress however, increases compounds known as reactive oxygen species (ROS) being toxic to the plants. One of the key nutrients, which aids the plants under environmental stress, is Potassium (K). It is known that optimization of K supply will mitigate the impacts of osmotic stress via increased stomatal conductance and improved assimilate translocation leading to less ROS production. In this study, we have investigated the impacts of K supply on plant water relations (e.g. water use efficiency WUE, stomatal conductance gs and assimilation AN) under osmotic stress conditions. Moreover, the dynamics of most important ROS (hydrogen peroxide H2O2, and Super oxide O2-) and antioxidants enzymes (catalase CAT, glutathione reductase GR, ascorbate peroxidase APX and super oxide dismutase SOD) were studied. Finally, Massive Analysis of CDNA Ends (MACE) was performed to observe the whole genome transcriptional responses to potassium supply under osmotic stress conditions. K supply had a positive effect on biomass-WUE, AN and gs leading to increased biomass under osmotic stress conditions. Contrarily, when low K supplied plants were treated with osmotic stress, reduced biomass was observed caused by severe ROS damage. Under the latter conditions, high activity of GR and APX was observed; nevertheless, these high activities were not sufficient to detoxify high H2O2 and O2- levels. The whole genome transcriptional response showed that low K supply plants exposed to osmotic stress were subjected to massive whole genome expression in order to resist the stress condition, costing them considerable energy consumption and eventuating in limited yield achievement. It is concluded that potassium supply under osmotic stress mitigated the photo-oxidative damage mainly via improved photosynthesis and avoiding ROS generation rather than high antioxidant activity. Optimization of K nutrient under osmotic stress recovers most of the changes in the metabolism pathways back to control conditions.

This is the first volume to provide comprehensive coverage of the biology of water use efficiency at molecular, cellular, whole plant and community levels. While several works have included the phenomenon of water use efficiency, and others have concentrated on an agronomic framework, this book represents the first detailed treatment with a biological focus. The volume sets out the definitions applicable to water use efficiency, the fundamental physiology and biochemistry governing the efficiency of carbon vs water loss, the environmental regulation of this process and the detailed physiological basis by which the plant exerts control over such efficiency. It is aimed at researchers and professionals in plant physiology, biochemistry, molecular biology, developmental biology and agriculture. It will also inform those involved in formulating research and development policy in this topic around the world.

This book explores the impact of soil water deficiency on various aspects of physiological processes in plants. The book explains the effects under soil water deficit condition such as lowering of plant water content, disturbance in carbon metabolism such in photosynthesis, photorespiration and respiration as well as effects of soil water deficit on nitrogen metabolism. The book also educates the readers about, mineral nutrition under soil water deficit condition and roles of different nutrient to overcome water deficit. Changes in growth and development pattern of plant under soil water deficit condition and effects on growth and development are elaborated. This book is of interest to teachers, researchers, scientists in botany and agriculture. Also the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, soil science, and environmental sciences. National and international agricultural scientists, policy makers will also find this to be a useful read. The in depth description of the major physiological issues in plants under soil water deficit that are presented in this book will help breeders tailoring crops for desirable physiological survival traits in the face of increasing soil water deficit. This book is an impactful addition to the library of any faculty members, researchers, agricultural policy planner, post graduate or student studying in plant physiology, biochemistry, microbiology and other subjects related to crop husbandry.
