Book Chapter Title:

Genetic Improvements of Traits for Enhancing NPK Acquisition and Utilization Efficiency in Plants

Book Chapter Number: 15

Abstract

Nitrogen, phosphorus, and potassium (NPK) are three important essential macronutrients for plant growth and development. As soil has been frequently overexploited, their availability might be an issue in modern agricultural practices. NPK macronutrients are limiting factors and therefore frequently added as chemical fertilizers in the agricultural system. The high cost of fertilizers use and adverse environmental impact underscore the importance of improving the efficiency of plants to capture these nutrients from soil. A better understanding about the biochemical and genetic pathways, key regulatory steps, genes, and quantitative trait loci involved in the acquisition and utilization of NPK nutrients by plants is necessary for the development of important tools for modern plant molecular breeding. The root system and rhizosphere processes play important role in the acquisition of mineral nutrients, including NPK, and effective root system architecture is important in breeding crop genotypes for high NPK use efficiency. The use of molecular markers has revolutionized the pace and precision of molecular-assisted breeding. The tremendous advances in the evolution of molecular marker systems and respective detection platforms provide new opportunities for the development of NPK-efficient genotypes through molecular breeding programs, which are discussed in this chapter.

This book presents the latest understanding of molecular and genetic bases of macro-nutrient use efficiency to develop strategies for improvement of overall nutrient use efficiency and nutrient stress tolerance. Plant Nutrient Use Efficiency (NUE), represents a question of process optimization in response to the increasing fragility of the natural resource base and threats to food grain security across the globe. This book is the first to present information key to the further improvement of macro NUE, a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. Plant Macro-Nutrient Use Efficiency improves understanding of the complex mechanisms regulating macro NUE for developing modern varieties that are more resilient to nutrient stresses. Identification of the potential novel genes responsible for NUE and nutrient stress tolerance in crop plants will contribute to understanding the molecular mechanisms of crop responses to nutrient stresses. This edited volume is an excellent, all-inclusive reference source of knowledge with both foundational and translational insights and is useful for those in all fields of plant science research.
