This study aims to explore the genetic determinants of root architecture in legumes and their implications for nutrient uptake efficiency. By examining various genetic traits and mechanisms, the study seeks to provide a comprehensive understanding of how root system development influences nutrient acquisition in legume crops. The study identifies several key genetic traits and mechanisms that significantly influence root system architecture (RSA) and nutrient uptake in legumes. Notable traits include root length, root branching, root diameter, and root proliferation rate, which are genetically defined and can enhance water and nutrient uptake under stress conditions. Genome-wide association studies (GWAS) have revealed significant single nucleotide polymorphisms (SNPs) and quantitative trait loci (QTLs) associated with these root traits, providing insights into the genetic architecture of legume roots. Advances in high-throughput phenotyping and omics approaches have further facilitated the dissection of genomic, proteomic, and metabolomic structures of these traits, aiding in the development of drought-tolerant and nutrient-efficient cultivars. Understanding the genetic basis of root architecture in legumes is crucial for improving crop cultivation and nutrient efficiency. By identifying and utilizing beneficial genetic variations, breeders can develop legume varieties with optimized root systems that enhance water and nutrient uptake, thereby improving yield and resilience under various environmental conditions. This knowledge is pivotal for addressing food security challenges and promoting sustainable agricultural practices.
