Dissection of the network underlying agronomic traits in soybean

Many agronomically important traits exhibit modularity and tend to be tightly integrated.The understanding of how traits become
associated or correlated is essential in the improvement of complex traits. Soybean (Glycine max L Merr) is a major crop of
agronomic importance as the predominant source of animal feed protein and cooking oil, which was domesticated fromwild soybean
(G. soja Sieb & Zucc) in China 5,000 years ago. Understanding soybean domestication and improvement and a comprehensive
dissection of the genetic basis of agronomic traits is important for soybean improvement. By analysis of several hundred re-sequenced
wild, landrace and improved soybean accessions, we detected 230 selective sweeps and 162 selected copy number variants. Combined
with previous quantitative trait loci (QTL) information, we find that, of the 230 selected regions, 96 correlate with reported oil QTLs
and 21 contain fatty acid biosynthesis genes, 96 of which correlate with reported oil QTLs. Moreover, we detected more than two
thousands association signals via a comprehensive GWAS for dozens of agronomic traits. Through modeling analysis, we find that
amount of association sites are tightly linked and form a complex network to regulate the modularity of different complex traits. This
study provides valuable resources for genomics-enabled improvements in soybean molecular breeding.
