Produktbeschreibung

Abiotic stresses caused by drought, salinity, toxic metals, temperature extremes, and nutrient poor soils are among the major constraints to plant growth and crop production worldwide. While crop breeding strategies to improve yields have progressed, a better understanding of the genetic and biological mechanisms underpinning stress adaptation is needed. Genes For Plant Abiotic Stress presents the latest research on recently examined genes and alleles and guides discussion of the genetic and physiological determinants that will be important for crop improvement in the future.

Genes For Plant Abiotic Stress follows a logical approach, covering water stress, poor quality soil, and temperature extremes independently, and then demonstrating how signal pathways transmitting different stress conditions can be shared. Each section covers key genes in future crop improvement strategies, and provides an in-depth analysis of the molecular mechanisms by which these genes might influence plant stress adaptation. Special emphasis is given to the technical challenges associated with practical application. Contributed by global experts in the field, this book will be an invaluable reference for researchers, industry personnel and students in agronomy, horticulture, crop breeding, biotechnology, plant biology and molecular genetics.

Key Features:
Highlights key genes that can be manipulated to develop stress resistance in crops
Covers the spectrum of major abiotic stresses ranging from temperature and water stress to poor soil conditions
Coalesces current knowledge and provides direction for future research
Features chapters from leading experts worldwide
