Legumes are an imperative source of food and proteins across the globe. They also improve soil fertility through symbiotic nitrogen fixation (SNF). Genome editing (GE) is now a novel way of developing desirable traits in legume crops. Genome editing tools like clustered regularly interspaced short palindromic repeats (CRISPR) system permits a defined genome alteration to improve crop performance. This genome editing tool is reliable, cost-effective, and versatile, and it has to deepen in terms of use compared to other tools. Recently, many novel variations have drawn the attention of plant geneticists, and efforts are being made to develop trans-gene-free cultivars for ensuring biosafety measures. This review critically elaborates on the recent development in genome editing of major legumes crops. We hope this updated review will provide essential informations for the researchers working on legumes genome editing. In general, the CRISPR/Cas9 novel GE technique can be integrated with other techniques like omics approaches and next-generation tools to broaden the range of gene editing and develop any desired legumes traits. Regulatory ethics of CRISPR/Cas9 are also discussed.
