Spatial composition and synteny of the T. fasciculata and T. leiboldiana genomes. A) Circular overview of the main scaffolds of the T. fasciculata (right) and T. leiboldiana (left) genome assemblies. Scaffolds 25 and 26 of T. leiboldiana are not shown due to their reduced size. Going inwards, the tracks show: (1, blue) gene count; (2, yellow) proportion of transposable element (TE) content; (3, red), and GC content per 1-Mb windows. B) TE and GC contents, GC content exclusively in TEs, and genic content in a triplet of syntenic scaffolds between Ananas comosus (LG3, black), T. fasciculata (scaffold 4, gray), and T. leiboldiana (scaffold 1, green; see Supplementary Fig. S6 for other syntenic chromosomes). Species names are abbreviated as A.com, T.fas, and T.lei, respectively. Note that the TE content was directly estimated on the soft-masked positions of the 3 reference genomes. Given that TE annotation approach used on the Tillandsia genomes differs from that on the A. comosus (F153) genome, the observed among-species difference in TE content should not be interpreted too strictly. C) Syntenic plot linking blocks of orthologous genes between A. comosus, T. fasciculata, and T. leiboldiana. The size of each scaffold on the y axis is proportional to genic content and therefore does not represent the true scaffold size. Color-filled boxes indicate scaffolds with reversed coordinates as compared to the sequences in A. comosus.
