Book excerpt: Postharvest environmental conditions of fruits and vegetables significantly affect quality and shelf life. Bioengineering fruits and vegetables, however, can enhance their value and durability. This book addresses the issues related to postharvest losses in fruits and vegetable crops using cutting-edge technologies, bringing together the most recent developments, such as gene overexpression approaches (enzymes, transcriptional factors, or combinatorial engineering), promoter engineering, enhancing postharvest stability (shelf life), epigenetic regulation, antioxidant-regulated expression, metabolic engineering, and regulation of postharvest pathogen infection and decay using biotechnological tools and much more. The book throws light on the current status as well as future prospects in this field as well.
