Features of the expression dynamics of lncRNAs. a The Log2(FPKM) expression level of coding RNAs, lncRNAs and TE-lncRNAs, based on the maximum expression of each lncRNA across datasets. b The correlation (log2(Fold Change)) of TE -lncRNAs and the closest neighboring gene under different stress conditions. The blue curve indicates the best fit across all of the plotted points and clearly indicates a strong positive correlation from when log2(Fold Change) varies between roughly − 5 and 5. The linear correlation of r = 0.48 is indicated in the graph. c This figure reports the number of differentially expressed lncRNAs under different stress conditions and developmental stages. The blue histogram on the left shows how many lncRNAs were differentially expressed under different conditions. The red histogram, coupled with the dot plot below, represent the distribution of differentially expressed lncRNAs among stress and stages. For example, the blue graph on the left indicates that 187 lncRNAs were differentially expressed under heat stress in V3. Of these, 38 were detected only under heat stress, as indicated by the graph in red, while 11 were differentially expressed under heat stress at both the V3 and V4 stages and 6 were differentially expressed under heat stress at both the V3 and V6 stages
