Introduction

The growing global population coupled with the increasing challenges of climate change, limited arable land, and environmental stressors pose significant threats to global food security. Meeting the ever-rising demand for food requires innovative approaches to enhance crop productivity while minimizing the environmental impact of agriculture. Genetic engineering, with its ability to introduce precise modifications into crop genomes, holds immense promise for addressing these challenges and revolutionizing agricultural practices [1]. Genetic engineering techniques, such as gene editing, transgenic approaches, and RNA interference, have opened up new possibilities for crop improvement. These techniques enable scientists to precisely manipulate the genetic material of plants, allowing for the introduction of desired traits or the modification of existing ones. By targeting key genes involved in yield, disease resistance, nutrient uptake, and stress tolerance, genetic engineering offers a powerful tool for enhancing crop productivity and sustainability. The advantages of genetic engineering in crop improvement are manifold [2-5]. It offers the potential for accelerating the breeding process by bypassing the lengthy and unpredictable traditional breeding methods. Genetic engineering can introduce specific traits into crops that may not be readily available in their natural gene pool, such as resistance to devastating pathogens or tolerance to abiotic stresses like drought or salinity. Furthermore, the precise nature of genetic modifications allows for targeted changes without disrupting the overall genetic integrity of the plant. However, the adoption of genetically engineered crops is not without controversy. Concerns over the safety of genetically modified organisms (GMOs) have raised public scrutiny and regulatory challenges [6, 7]. It is imperative to thoroughly assess the potential risks and benefits associated with genetically engineered crops and ensure their responsible deployment. This review aims to provide an overview of the current state of research on improving crop productivity through genetic engineering. We will explore the latest advancements in genetic engineering techniques, the specific traits targeted for improvement, and the outcomes achieved in various crop species. Furthermore, we will discuss the implications, challenges, and future prospects of genetic engineering in crop improvement, considering both scientific and societal perspectives. By critically examining the existing literature and synthesizing the findings, this review seeks to contribute to the understanding of how genetic engineering can be effectively harnessed to enhance crop productivity and sustainability [8-14]. Ultimately, this knowledge can guide future research efforts and inform decisionmaking processes for the responsible implementation of genetically engineered crops.
