Comparison of the differentially expressed genes (DEGs) in response to submergence stress in soybean. (a) The number of up- and down-regulated genes under submergence conditions. (b) A cluster heat map of DEGs resulting from submergence treatment. Red, up-regulated genes; blue, down-regulated genes. Darker color indicates greater significance. (c) Venn diagram of common DEGs under 3, 6, 12 and 24-h submergence treatments in soybean seedlings. CK: Control; F: Flooding (submergence treatment).
