RNA structure contributes to translational subgenome asymmetry in tetraploid Kronos. a Scatter plot showing the correlation between the absolute values of difference of average base-pairing probability (BPP) and translation efficiency (TE) difference between the A and B subgenome homoeologs (n = 4283, P < 10-16). b Arc diagram showing the RNA structure of the homoeologous pair of protein translation factor SUI1, TRITD2Av1G085990 in the A subgenome, and TRITD2Bv1G091150 in the B subgenome, with higher TE in the A subgenome than in the B subgenome. Every arc corresponds to one base pair, the pairing nucleotides with pairing probability lower than 0.4, between 0.4 and 0.8, or over 0.8.are indicated by lines in yellow, green, or blue, respectively. c Arc diagram showing the RNA structure of the homoeologous pair of 60S ribosomal protein L18a, TRITD1Av1G210460 in the A subgenome, and TRITD1Bv1G213890 in the B subgenome, with lower translation efficiency in the A subgenome than that in the B subgenome. Otherwise in Fig. 4b. d Volcano plot showing the correlation coefficients between difference of average BPP and TE difference, for genes related to different GO functions. The red line indicates the cut-off P value of 0.05, the points above the red line indicate a significant correlation between the BPP difference and TE difference for the groups of homoeologs with specific functions. The GO function items related to abiotic stress response, biotic stress response, metal ion response, phytohormone signaling are colored in red, orange, purple, or black, respectively
