Fig. 2: Genomic features of P. chienii.

a Pictures of a wild P. chienii tree used for genomic DNA sequencing. b Circos plot of P. chienii genome. Track Ⅰ represents the length of the chromosomes (Gb); Ⅱ and Ⅲ represent GC content and gene density, respectively; Ⅳ-Ⅵ represent gene expression without or with MeJA treatment, respectively; Ⅶ-Ⅸ show the distribution of transposons, Gypsy, and Copia LTRs, respectively. These features were calculated in 10 Mb windows. Center, the syntenic regions were linked by curve lines. c Analysis of insertion time based on the total LTR. d Analysis of insertion time based on different types of LTR. e Venn diagram for orthologous protein-coding gene clusters in P. chienii, T. grandis, T. mairei, T. yunnanensis, and T. wallichiana. The number in each sector of the diagram represents the total number of genes across different comparisons. f Gene family expansion and contraction during the evolution of green plants. The maximum likelihood phylogeny was built with a number of low-copy orthologous groups. Numbers on branches are the sizes of expanded (red) and contracted (green) gene families at each node.
