Plant metal interaction : emerging remediation rechniques


Plant metal interaction : emerging remediation rechniques by Ahmad, Parvaiz

This edited volume Plant Metal Interaction: Emerging Remediation Techniques includes 25 chapters that will shed light on different heavy metals, their impact on plants, and remedial approaches. Chapter 1 is an overview on aluminum toxicity in plants, in which the author describes the impact of aluminum on plants, nutrient uptake, gene expression, and so on. Chapter 2 is about the effect of copper stress on plant growth, photosynthesis, and signal transduction. Chapter 3 discusses the effect of lead on plant and human DNA and its damages and its impact on the environment. Chapter 4 describes resistance of plants to Cu stress (transgenesis) and includes a discussion of Cu as an essential element, the toxic effects of high concentrations of Cu, maintenance of intracellular Cu homeostasis, construction of transgenic plants resistant to heavy metals, etc. Chapters 5, 6, and 7 throw light on boron toxicity, chromium toxicity, and antioxidative properties of selenium on plants. Chapter 8 is about the mitigation of heavy metal stress by brassinosteroids in plants. Chapters 9, 10, and 11 are related to plant metallothioneins and phytochelatins; biosynthesis of phytochelatins, phytochelatins, mediated redox homeostasis, and metallothioneins are also well-documented. Chapters 12, 13, and 14 describe the role of plants in detoxification and tolerance of heavy metals such as mercury and trace elements from the soil and water. Chapter 15 is related to phytoextractiondthe use of plants to remove heavy metals from soil. Chapters 16, 17, 18, and 19 explain the efficient role of different plants in accumulating heavy metals from water and soil. Genetic strategies for phytoremediation potential in plants are also thoroughly explained. Chapters 20 and 21 are related to phytoremediation of heavy metals in the presence of microbes and plant growthepromoting rhizobacteria. Chapters 22 and 23 are about the molecular mechanism and role of adenosine triphosphatase (HMA2, HMA3, and HMA4) in the hyperaccumulation of heavy metals. Chapters 24 and 25 explain the impact of heavy metals on plants and their role in signaling.
