The data are the means from four biological replicates. The fold changes was calculated using the formula ${log}_{2}^{(s a l t / c o n t r o l)}$ . Values were presented as the mean ± standard deviation of four biological replicates. CK, control treatment; NS, neutral-salt stress; AS, alkaline salt stress. W, wild soybean; S, semi-wild soybean; M, cultivated soybean.

Significant difference at p < 0.05.
