Advancements in Genetic Engineering for Enhanced Traits in Horticulture Crops: A Comprehensive Review

Abstract

Genetic engineering has emerged as a powerful tool in the field of horticulture to enhance the traits of crops, leading to improved yield, quality, and resistance to biotic and abiotic stresses. This comprehensive review explores the recent advancements in genetic engineering techniques applied to horticulture crops, providing a detailed overview of the innovative strategies employed to manipulate plant genomes. The review begins by discussing the evolution of genetic engineering in horticulture, highlighting key milestones and breakthroughs that have paved the way for current advancements. It covers a range of techniques such as CRISPR-Cas9, RNA interference, and synthetic biology, shedding light on their applications in modifying specific genes responsible for desired traits. The main focus of the review is on the enhancement of key horticultural traits, including disease resistance, pest resistance, abiotic stress tolerance, and post-harvest attributes. Examples from various horticultural crops, such as fruits, vegetables, and ornamental plants, illustrate the success stories and potential applications of genetic engineering in each category. The ethical and regulatory aspects of genetic engineering in horticulture are also explored, addressing concerns related to environmental impact, biodiversity, and consumer acceptance. The review emphasizes the importance of responsible and sustainable practices in the application of genetic engineering to ensure the long-term benefits without adverse consequences. Furthermore, the review delves into emerging trends and future prospects in the field, including the potential of genome editing for precision breeding, the use of omics technologies for targeted trait improvements, and the integration of genetic engineering with other breeding techniques. It also discusses the challenges and opportunities associated with the global adoption of genetically modified horticulture crops.
