A thoroughly up-to-date exploration of nutrient uptake in plants
In Plant Ionomics: Sensing, Signaling and Regulation, accomplished botanists and researchers Dr. Vijay Singh and Dr. Manzer Siddiqui deliver an up-to-date discussion on the sensing, signaling, and regulation of nutrient uptake in plants under a variety of conditions. The book offers an accessible and easy-to-use reference for researchers with an interest in plant ionomics, combining the latest research from leading laboratories around the globe.
The authors provide coverage of a variety of critical topics, including plant and soil nutrient stoichiometry, nutrient management and stress tolerance in crops, and the relationship between agricultural production and nutrient applications. Readers will also find: - A thorough introduction to nutrient regulation and abiotic stress tolerance in plants - In-depth discussions of nutrient uptake and transport in plants and the role of nutrients in ROS metabolism - Practical explorations of nutrient and sugar signaling and associated gene networks in plants - Extensive treatments of the role of nutrients in plant-microbe interactions and nutrient-use efficiency in plants
Perfect for students, researchers, academics, and scientists with an interest in plant nutrition, Plant Ionomics: Sensing, Signaling and Regulation will also earn a place in the libraries of professionals in the agriculture and pharmaceutical industries.
