The predicted function of lncRNAs regulating PCGs in trans. a 1029 PCGs and 387 lncRNAs composed 2072 pairs of positive in trans, the color-axis of heatmap is the log₁₀ ^FPKM+1. The correlation coefficients (r) ≥0.9, p value ≤ 0.05. b 1047 and 369 lncRNAs composed 1803 pairs of negative regulatory modes in trans. The correlation coefficients (r) ≤ −0.9, p value ≤ 0.05. c-d GO analysis and pathway analysis of coding genes associated with negative correlation coefficients, p value ≤ 0.05; (e-f). GO analysis and pathway analysis of PCGs associated with positive correlation coefficients, p value ≤ 0.05. The x-axis of c/d/e/f graphs is the –log₁₀ ^{p value}
