Genetically modified fruit and vegetable - An overview on senescence regulation, postharvest nutraceutical quality preservation and shelf life extension

Abstract

Genetic engineering techniques offer opportunities for deliberate modulation and enhance the bio-functionality and bio-availability of horticultural crops, particularly fruit and vegetable which can aid in realising the goals of food and nutritional security for the burgeoning world population. The need of the hour calls upon us to use modern-day technologies such as genetic engineering in horticultural field as well for eradication of globally widespread hunger and malnutrition while the population is escalating and climate change is imminent. However, rigorous testing and trials to elucidate any unfounded fear and notion are warranted before the release of genetically modified (GM) crops for ensuring environmental and food safety. In this review, there is an attempt by the authors to compile and discuss the modulation in postharvest biology, edible quality, functional properties and storage life of genetically modified fruit and vegetable along with challenges in their use and consumer acceptance. The review also provides an outline of GM fruit and vegetable research prioritisation along with road map for future work.
