Comparative genomic analyses of field pennycress with relatives. a Hi-C interaction heatmap for pennycress genome showing interactions among seven chromosomes (Chr1–7). b Genomic features of pennycress (Ta) vs. Brassica rapa (Br). Tracks from outside to inside (a–g) are as follows: chromosomes, retrotransposon density, DNA transposon density, long terminal repeat retrotransposon (LTR) density, gene density, GC content, and collinearity between both genomes. c Maximum likelihood tree and estimation of divergence times in Brassicaceae. d Genome collinearity dot plot and Ks distribution between pennycress (Ta) and A. thaliana (At). e Age distribution of transversion substitutions at fourfold degenerate sites (4DTv) distance values between orthologs of pennycress and its relatives. f Insertion time distribution of LTR of pennycress and its relatives
