Identification of QTN-by-environment interactions and their candidate genes for soybean seed oil-related traits using 3VmrMLM.

The above results indicated that GEIs, together with drought response genes in co-expression network, may respond to drought, and play important roles in regulating seed oil-related traits together with oil metabolism genes. These results provide important information for genetic basis, molecular mechanisms, and soybean breeding for seed oil-related traits.
