Fig. 3

The fraction of P. trichocarpa chloroplast genome covered by the assemblies of the simulated short reads under multiple k-mer values. The resulting assemblies with genome fractions > 128 kbp are shown in this figure. The quadrant structure of the chloroplast genome is composed of large single-copy (LSC) and small single-copy (SSC) regions separated by a pair of inverted repeats (IRa and IRb); the regions of both IRa and IRb are labeled with the wide transparent yellow band. The x-axis and y-axis represent the genome assemblies for the simulated reads data and the locations of the reference genome covered by contigs from the genome assemblies, respectively
