Plant proteomics refers to the broad study of proteins focused on their structures and functions as governed by the physiological metabolism of plant cells. It is used in researches for studying gene products and validating their predicted biological functions. It also plays an integral role in understanding the major biochemical signaling pathways involved in the response of plants to their environment. Biotechnological applications in plant breeding rely on the data gathered from proteomic investigations. Proteomics has made it possible to identify a large variety of proteins that are essential for enhancing product quality, preserving crop health and developing resistance to stressors. This book explores the technologies, strategies and applications of plant proteomics. It consists of contributions made by international experts. A number of latest researches have been included herein to keep the readers updated with the latest concepts in this area of study.
