Plant Cells and their Organelles

About the EditorsWilliam V. Dashek, Emeritus Professor, Mary Baldwin College, USA Dr. Dashek is the recipient of BS, MS and Ph.D. degree from Marquette University where he was a National Institute of Health pre-doctoral trainee. He was a post-doctorate fellow at the Michigan State University Plant research Laboratory. Subsequently, he began a lengthy Academic teaching and research career. Currently, Dashek is retired writing advanced textbooks. Gurbachan S. Miglani, Visiting Professor, School of Agricultural Biotechnology, Punjab Agricultural University, IndiaDr. Miglani obtained B.Sc. (Agri. & A.H.) and M.Sc. (Genetics) from Punjab Agricultural University (PAU), Ludhiana, Punjab, India and Ph.D. from Howard University, Washington, D.C. During his 35-year teaching stint at PAU he taught general and specialized courses in genetics. Even after retirement Miglani is still teaching molecular genetics and biotechnology at PAU. In addition to research and review papers, popular science articles, laboratory manuals he has published a dozen books and presently he is writing his next book.
