Plant Macronutrient Use Efficiency presents an up-to-date overview of the latest research on the molecular and genetic basis of macro-nutrient use efficiency (NUE) in plants, and strategies that can be used to improve NUE and nutrient-associated stress tolerance in crop plants. Plant NUE is a measure of how efficiently plants use available nutrients and an understanding of plant NUE has the potential to help improve the use of limited natural resources and to help achieve global food security. This book presents information important for the development of crop plants with improved macro-NUE, a prerequisite to reducing production costs, expanding crop production into noncompetitive marginal lands with low nutrient resources, and for helping to prevent environmental contamination.

Plant Macronutrient Use Efficiency provides a comprehensive overview of the complex mechanisms regulating macro-NUE in crop plants, which is required if plant breeders are to develop modern crop varieties that are more resilient to nutrient-associated stress. Identification of genes responsible for macro-NUE and nutrient-related stress tolerance in crop plants will help us to understand the molecular mechanisms associated with the responses of crop plants to nutrient stress.

This volume contains both fundamental and advanced information, and critical commentaries useful for those in all fields of plant science research.

Provides details of molecular and genetic aspects of NUE in crop plants and model plant systems Presents information on major macronutrients, nutrient sensing and signaling, and the molecular and genomic issues associated with primary and secondary macronutrients Delivers information on how molecular genetic information associated with NUE can be used to develop plant breeding programs Includes contributions from world-leading plant nutrition research groups

Plant Micronutrient Use Efficiency: Molecular and Genomic Perspectives in Crop Plants presents information on the complex mechanisms regulating micronutrient use efficiency in plants. Understanding this science is essential for the development of new varieties of crop plants that are more resilient to micronutrient stress, as well as plants with increased bioavailable concentrations of essential micronutrients. This book explores the discovery of novel genes and key metabolic pathways associated with micronutrient use efficiency in plants, gives an analyses of the gene expression patterns in plants in response to low and/or high nutrient levels, and investigates the potential functions of these genes and their products.

Strategies to enhance micronutrient use efficiency and stress tolerance, to develop bio-fortified crop, and to improve the sustainable utilization of natural resources are critically evaluated. The book contains both fundamental and advanced information as well as critical commentaries that are useful for those involved in the various fields that make up the plant sciences.

Presents in-depth information on mineral nutrition, including coverage of all the major micronutrients Explores the molecular and genetic aspects of micronutrient use efficiency in crop plants Provides information and critical discussion of the latest developments in the micronutrient biofortification of crop plants with an aim to prevent micronutrient deficiencies in humans Includes contributions from experts in plant micronutrient use efficiency and crop biofortification

This work contains most of the conclusions reached by the geneticists, anthropologists, and linguists at the meeting `Prehistoric Iberia'. The novel conclusions reached include the following: there is no evidence of the demic diffusion model of people substitution in Iberia during the Mesolithic-Neolithic transition; new technologies were probably reached by circum-Mediterranean navigation; present day Iberians are genetically very similar to North African populations and also to other more distant Eastern Mediterraneans, including Turks; Arab invasions in North Africa and Spain in 711 AD did not result in a massive gene flow; North African Berbers and Spaniards have maintained their old genetic identity - this invasion was mostly religious and cultural; Celts in Iberia are difficult to find; and Basque and Berber languages are similar to many other extinct `Usko-Mediterranean' languages (Etruscan, Minoan). These `older languages' were later substituted by the Euro Asiatic languages (Latin, Greek, German).Finally, the Saharan area is considered as a radiation focus of peoples, (and languages) who were forced to emigrate from a fertile area where hyper-arid conditions began to develop after 7000 BC.

As the demand for data reliability increases, coding for error control becomes increasingly important in data transmission systems and has become an integral part of almost all data communication system designs. In recent years, various trellis-based soft-decoding algorithms for linear block codes have been devised. New ideas developed in the study of trellis structure of block codes can be used for improving decoding and analyzing the trellis complexity of convolutional codes. These recent developments provide practicing communication engineers with more choices when designing error control systems. This text combines trellises and trellis-based decoding algorithms for linear codes together in a simple and unified form. The approach is to explain the material in an easily understood manner with minimal mathematical rigour. The book is intended for practicing communication engineers who want to have a fast grasp and understanding of the subject. Only material considered essential and useful for practical applications is included. This book can also be used as a text for advanced courses on the subject.

Boron is one of the essential micronutrients for higher plants growth and development, and more and more studies have been conducted to establish boron as an essential element in animals and humans. This book reviews all aspects of boron research in recent years and is based on the Third International Symposium on all Aspects of Plant and Animal Boron Nutrition which was held in Wuhan, P.R. China. The following issues are discussed:boron sorption mechanisms in soilsdeficiency and toxicity of boronboron fertilizer applicationbasic research on the physiology and molecular biology of plant boron nutritionthe nutritional function of boron in animals and humansThis book is aimed at scientists, Masters or PhD students focusing on boron research field. Furthermore, it provides managers involved in agricultural production with an important reference to recent developments in boron nutrition research.
