The data are the means from four biological replicates. The fold changes was calculated using the formula log2(salt/control). 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.
