Advancement of genetic engineering applications for enhancing legume crop improvement in agriculture

Abstract

Legumes are a vital component of agriculture, providing essential nutrients to both humans and soil through their ability to fix atmospheric nitrogen. However, the production of legume crops is often hindered by various biotic and abiotic stresses, limiting their yield and nutritional quality of crops by damaging plant tissues, which can result in lower protein content, reduced levels of essential vitamins and minerals, and compromised seed quality. This review discusses the recent advancements in technologies that are revolutionizing the field of legume crop improvement. Genetic engineering has played a pivotal role enhancing legume productivity. Through the introduction of genes encoding for enzymes involved in nitrogen fixation, leading to higher yields and reducing the reliance on synthetic fertilizers. Additionally, the incorporation of genes conferring disease and pest resistance has significantly reduced the need for chemical pesticides, making legume cultivation more sustainable and environmentally friendly. Genome editing technologies, such as CRISPR-Cas9, have opened new avenues for precision breeding in legumes. Marker-assisted selection and genomic selection are other powerful tools that have accelerated the breeding process. These techniques have significantly reduced time and resources required to develop new legume varieties. Finally, advancement technologies for legume crop improvement are aid and enhancing the sustainability, productivity, and nutritional quality of legume crops.
