Fig. 2From: Molecular adaptation to salinity fluctuation in tropical intertidal environments of a mangrove tree Sonneratia albaSignificant expression clusters in leaves. The lines represent mean expression levels (means of log2(FPKM value + 1)) of all genes in a cluster. The error bars represent the standard deviation. The observed and expected numbers of genes belonging to each cluster are labeled on the top of each graph. A permutation test was used to evaluate the significance of differences. The clusters with statistically significant difference in the number of DEGs are marked with triple (P-value < 0.01) asterisksBack to article page
