All of them have challenges in production in their specific agroecosystems under stress due to pests, diseases, salinity, drought, cold among others. Gene editing through CRISPR/Cas is a key tool for addressing critical challenges in agriculture by improving resilience to biotic and abiotic stress, increasing yield and enhancing the nutritional value of the crops. This approach allows precise mutation on site-specific gene at the DNA level, obtaining desirable traits when its function is altered. The CRISPR/Cas system could be used as a transgene-free genome editing tool when the ribonucleoprotein (RNP) acts as a carrier to delivered the CRISPR/Cas components into the plant cell protoplasts, or when the tRNA-like sequence (TLS) motifs are fused to single-guide RNA (sgRNA) and Cas mRNA sequence and expressed in transgenic plants rootstock to produce \"mobile\" CRISPR/Cas components to upper tissue (scion). Those innovations could be a potential approach to strengthen the Peruvian agriculture, food security and gricultural economy, especially in the tropical, Andean and coastal regions. This review article examines the advances and strategies of gene editing, focusing on transgene-free methodologies that could be adopted for research, development and use, and also identifies potential applications in key crops for Peru and analyzes their impact in the productivity and reduction of agrochemicals dependence.

Grain legumes have long been identified as a valuable nutritional source for humans. However, their significance extends beyond nutrition to global food security, reducing reliance on chemical fertilizers, improving soil health and increasing resilience to climate change. Recognizing their vital importance in nutrition and agricultural production, scientists have worked persistently to uncover new genetic traits in legumes, resulting in enhanced yields, improved nutritional value and increased stress tolerance. Recently, the availability of genomic resources for new traits in grain legume plants has greatly increased, laying the groundwork for the adoption of advanced breeding technologies. Gene editing has shown significant potential to improve crop outcomes. This review critically examines the latest developments in gene-editing techniques specific to major grain legumes, focusing on their application in enhancing legume crops with significant agronomic characteristics. The article also shows the potential advantages associated with these advancements. Over the years, advancements in technologies such as Transcription Activator-Like Effector Nucleases (TALENs), Zinc Finger Nucleases (ZFNs), Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR/Cas9), and the more recent Prime Editing technique have significantly contributed to genetic enhancements. These innovations have improved nutritional and market traits, boosted farming incomes, and increased the accessibility of affordable nutritious food, particularly in developing nations.
