Dr. Dharmendra K. Gupta is Director (S) and Scientist “F” in the Ministry of Environment, Forest and Climate Change, Government of India at New Delhi, India and already published more than 115 refereed research papers/review articles in peer reviewed journals and in books, also edited 18 books from Springer and NOVA publishers. His field of research includes abiotic stress by radionuclides/heavy metals and xenobiotics in plants; antioxidative system in plants, environmental pollution (radionuclides/heavy metals) remediation through plants (phytoremediation). According to google scholar his h-index is 37.           Prof. Francisco J. Corpas is Research Professor of the Spanish National Research Council (CSIC) who has more than 28 years of research experience in the metabolism of Reactive Oxygen, Nitrogen and Sulfur Species (ROS, RNS and RSS, respectively) in higher plants under physiology and environmental stress conditions. Special interests are the implications of these reactive species in fruit ripening and the nitro-oxidative metabolism of plant peroxisome. He was the Head of the Department of Biochemistry, Cell and Molecular Biology of Plants (2014-2018) at Research Institute named “Estación Experimental del Zaidín”-CSIC, Granada Spain. He has already published more than 224 refereed research papers/review articles in peer reviewed journals (according with Scopus database with h-index: 63) and edited seven books.
