This book focuses on the menace of metal pollution and its impact on plants, particularly food grains, pulse and vegetable plants covering morphological, anatomical, physiological and biochemical aspects. It includes comparative studies among metal hyper-accumulators (metallophytes) and non-accumulators including exogenous hormonal alleviation in them due to metal stress. Low dose stimulation effects are also reviewed. The most significant feature of the book is its extensive coverage of genomics, metabolomics, ionomics, proteomics and transcriptomics in metal non-hyper-accumulators and hyper-accumulators. Being an edited volume, the book incorporates a variety of research perspectives, enhancing the existing knowledge about metal pollution and points to newer avenues to be researched.
