From: Interspecific delimitation and relationships among four Ostrya species based on plastomes
Visualization of alignment of the four Ostrya species chloroplast genome sequences using O. trichocarpa as the reference. Grey arrows above the alignment indicate the orientation of genes. The vertical scale indicates the percentage of identity, ranging from 50 to 100%. The horizontal axis represents the coordinates within the chloroplast genome. Genome regions are color coded as protein-coding, rRNA coding, tRNA coding, and conserved non-coding sequences, respectively
