At any given moment, a number of innovations in life science research occurs. There has always been an ever-increasing demand for the interdisciplinary research in life science to solve the problems of mankind. It is a challenging task to bring the fruits of laboratory level research to the commercial level for the welfare of humans. This book is an attempt to keep abreast with the recent innovations made in various fields of life science research. The book encompasses topics ranging from prokaryotic microscopic organisms to eukaryotic higher plants, distributed in fifteen chapters for the benefit of graduate and postgraduate students as well as young researchers, scientists and professionals. The book deals with topics pertaining to natural sunscreens, secondary metabolites, genome editing, molecular markers, stress biology, crop improvement, herbal medicines, plant diseases, genetic engineering, biotechnology and aspects related to ecology. This book imparts the latest innovations and knowledge in the specific fields of life sciences. In addition, it also provides details of newer and state-of-the art technology/tools employed in achieving the potential of microbes and higher plants to make products that can be readily available for the welfare of humans. An insight for future perspectives has also been provided that makes this book highly useful and a must-read for students, researchers and professionals working in the field of microbiology, botany, biotechnology, agriculture, molecular biology, photobiology, ecology and other streams of life sciences.
