Transcriptome-wide association studies of SCC. a, b Manhattan plot of TWAS results (FDR < 0.05) for SCC at 20 DAF (a) and 40 DAF (b). Each point represents a single gene tested. Genomic positions of genes are plotted on the X-axis and the log-transformed FDR values of association between gene expression and SCC are plotted on the Y-axis. The genes positively or negatively associated with the SCC are plotted above or under the black bold line, respectively. The golden dots indicate genes involved in the phenylpropanoid biosynthesis pathway and secondary cell wall development identified in Arabidopsis. The dashed gray horizontal lines represent the significance level. c Venn diagram showing shared genes between significant genes identified by TWAS at 20 DAF and 40 DAF. d GO enrichment analysis of overlapped significant genes identified by TWAS at 20 DAF and 40 DAF. The dot size and color indicate the gene number and the range of FDR values, respectively
