Diurnal oscillation characteristics of protein-coding gene transcription in B. napus. A Proportions of genes with different expression signatures of protein-coding genes in B. napus. B The number of genes with overlapping rhythmic exons and introns. C The heatmap illustrates the diurnal oscillation of gene expression in rhythmic genes. D A frequency plot percentage of rhythmic genes with peak expression phase binned in 4h over 24h is presented. E The phase distribution of rhythmic genes, rhythmic exons, and rhythmic introns. F Spatial-specific clustering of time-series curves of rhythmic gene transcription. G Overlapping genes with oscillating exons and introns overlap with rhythmic genes. H Features of gene transcription at the indicated time point of LHY. (From left to right, they are BnaA10G0008600ZS, BnaC03G0001300ZS, and BnaC05G0010100ZS) I Diurnal fluctuations in high-amplitude homologous gene expression of LHY. (The red line represents BnaA10G0008600ZS, the blue line represents BnaC03G0001300ZS, and the green line represents BnaC05G0010100ZS) J Comparing amplitude, peak-to-trough ratio, and median of rhythmic gene expression with global gene expression
