Fig. 1

A circular visualization of chromosomes in Z. latifolia genome. The outermost plot represents ideograms of 17 chromosomes (scale mark = 5 Mb). Moving from the second outermost track to the innermost track, each concentric circle denotes the GC content, density of protein-coding genes, repeat sequence density, Gypsy-like element distribution and Copia-like element distribution. The innermost track indicates genomic synteny among the chromosomes.
