Legumes form symbiotic relationship with root-nodule, rhizobia. The nitrogen (N2) ?xed by legumes is a renewable source and of great importance to agriculture. Symbi- otic nitrogen ?xation (SNF) is constrained by multiple stresses and alleviating them would improve SNF contribution to agroecosystems. Genetic differences in adaptation tolerance to various stresses are known in both host plant and rhizobium. The discovery and use of promiscuous germplasm in soybean led to the release of high-yielding cul- tivars in Africa. High N2-?xing soybean cultivars are commercially grown in Australia and some countries in Africa and South America and those of pea in Russia. SNF is a com- plex trait, governed by multigenes with varying effects. Few major quantitative trait loci (QTL) and candidate genes underlying QTL are reported in grain and model legumes. Nodulating genes in model legumes are cloned and orthologs determined in grain le- gumes. Single nucleotide polymorphism (SNP) markers from nodulation genes are available in common bean and soybean. Genomes of chickpea, pigeonpea, and soy- bean; and genomes of several rhizobium species are decoded. Expression studies revealed few genes associated with SNF in model and grain legumes. Advances in host plant and rhizobium genomics are helping identify DNA markers to aid breeding of legume cultivars with high symbiotic ef?ciency. A paradigm shift is needed by breeding programs to simultaneously improve host plant and rhizobium to harness the strength of positive symbiotic interactions in cultivar development. Computation models based on metabolic reconstruction pathways are providing greater insights to explore genotype?phenotype relationships in SNF. Models to simulate the response of N2 ?xation to a range of environmental variables and crop growth are assisting re- searchers to quantify SNF for ef?cient and sustainable agricultural production systems. Such knowledge helps identifying bottlenecks in speci?c legume?rhizobia systems that could be overcome by legume breeding to enhance SNF. This review discusses the recent developments to improve SNF and productivity of grain legumes. MenosLegumes form symbiotic relationship with root-nodule, rhizobia.
