Introduction
Like other legumes, G. max requires low inputs of nitrogen fertilizer.G. max has root nodules that support nitrogen-fixing bacteria, which convert inaccessible atmospheric nitrogen to ammonia, a form readily accessible to plants. Nodulation by the bacteria,Bradyrhizobia japonicum, provides 50-75% of the nitrogen needed to support soybean production. Biological information![]() Glycine max has a complex and large genome (1.1 gigabases) with 20 haploid
chromosomes. G. max is a diplodized tetraploid (2n = 40). Ancestral genomic duplication created a genome where many soya genes (~75%) are represented by multiple copies. However, chromosomal changes have diplodized the tetraploid genome, so that the 20 haploid chromosomes now segregate like the homologous pairs of a diploid.
