a Characterization of the centromere of chromosome 6 in P. lindheimeri. From top to bottom are the sequences of the centromere satellite repeats, Gypsy/CRM type retrotransposons, Copia/Ale type retrotransposons, genes and RNA-Seq data from five different tissues. Centromeric regions extend 1 Mb to the left and right. b Satellite sequence motifs in the centromeric regions of three Physaria species. c Segmental duplications and tandemly duplicated genes in P. lindheimeri. Heatmaps in the circos plot represent gene density. Linkage regions represent SD regions between chromosomes, and colored markers on chromosomes represent centromeric regions. d GO enrichment analysis of tandemly duplicated genes. Statistical analysis was performed using a one-sided hypergeometric test and the Benjamini-Hochberg (BH) method to control the false discovery rate (FDR). Source data are provided as a Source Data file.
