ISBN: 9781633215931 出版年：2014 页码：260 Dharmendra Kumar Gupta Soumya Chatterjee Germany) Nova Science

Plants have a very specific and efficient mechanism to obtain, translocate and store nutrients from the surrounding environment. The precise mechanism that helps a plant in nutrient translocation from root to shoot also, in the same way, transfers and stores toxic metals within their structure. Metal toxicity generally causes multiple direct or indirect effects on plants, affecting nearly all of their physiological functions. Plant tolerance to heavy metals depends largely on plant efficiency in uptake, translocation and sequestration of heavy metals in specific cell organelles or specialized tissues. The main purpose of this book is to present a holistic view of the recent advancement in the field of accumulation and remediation using plants, the green solar powered alternative to ameliorate heavy metal from the polluted environment. The key features of the book are related to metal transporters and metal accumulation mechanisms under heavy metal stress in plants, plant transcriptional regulation and responses under metal contamination, multiple toxic metal contaminations and its phytoremediation approaches etc. Based on the advancement of research in recent years, the information compiled in this book will bring an in-depth knowledge on the bioaccumulation of metals, their transportation in natural conditions or genetically modified plants and their strategy to cope with the toxicity to survive in the hostile environment.
