To assess genome-wide structural and gene content variations across soybean genotypes and characterize their genomic distribution and functional associations.
Assessed structural variation and gene content variation across four soybean (Glycine max) genotypes.
Identified genomic differences using array hybridization and targeted resequencing.
Detected prominent regions of copy number and presence-absence variation on chromosomes 3, 6, 7, 16, and 18, despite low structural variation across many other chromosomes.
Showed that structural variation specifically enriches within gene-rich regions harboring clustered multigene families, primarily nucleotide-binding and receptor-like protein classes involved in biotic defense.
