A. Mujib is senior lecturer at the Department of Botany, Hamdard University, New Delhi, India. He received his Ph.D. degree from the University of Kalyani (India) working on in vitro studies of bulbous ornamentals. Later he was appointed to a position in the Department of Chemical Engineering, Indian Institute of Technology (IIT), Kharagpur. He teaches molecular genetics, cytogenetics, and plant biotechnology. His current research interests include somatic embryogenesis and gene expression, analysis of somaclonal variants with a focus on transposons, and in vitro mutagenesis using cell culture as a system. His scientific work has resulted in more than 55 publications including research papers, review articles, and book chapters. Jozef Samaj received his Ph.D. degree from the Comenius University in Bratislava, Slovakia. He completed three post-doctoral programmes supported by Eurosilva, the Alexander von Humboldt Foundation, and the EU Marie Curie Programme in well-recognized laboratories in Toulouse, Bonn, and Vienna. His scientific work has focused on the cell biology of somatic embryogenesis, lignification in tree species, arabinogalactan proteins, the cytoskeleton, and signalling proteins. Jozef Samaj has co-authored more than 60 research papers, reviews, and book chapters. Currently he is a senior lecturer and associate researcher at the Institute of Cellular and Molecular Botany in Bonn, Germany. His main research interest centers on the role of stress-induced MAP-kinase cascades in relation to vesicular trafficking and the cytoskeleton during stress responses in Arabidopsis thaliana.
