Figure 3: Whole-genome alignment and expansion of the G. arboreum genome.
From: Genome sequence of the cultivated cotton Gossypium arboreum
(a,b) Whole-genome alignments of G. arboreum on G. raimondii (a) and of G. raimondii on G. arboreum (b). Chromosomes from both genomes were plotted according to their assembled lengths. Each of the 13 chromosomes in a and b is designated by color; white blocks represent regions that could not be aligned. Only syntenic blocks of ≥2 Mb in length are shown. (c) Analysis of LTR number and insertion time in G. arboreum (Ga) and G. raimondii (Gr). Bars (left y axis) indicate the number of LTRs inserted at any specific time point, whereas curves (right y axis) represent the accumulated total number of LTRs throughout evolution. (d) In-depth study of a microsyntenic block on chromosomes 7 of G. arboreum (Ga07) and G. raimondii5 (Gr07). Yellow bars, gene models; green lines, syntenic gene pairs; blue bars, TEs present at the corresponding chromosomal locations in each genome. The total number of genes and TEs found in each region is shown beneath each schematic.
