Map of the soybean (Glycine max) chloroplast genome. This genome was used to engineer biotic stress tolerance against insects and herbicides. The quadripartite structure includes two copies of an IR region (IRA and IRB) that separate large single-copy (LSC) and small single-copy (SSC) regions [18]. a Circular form. The GC content graph (gray circle inside) marks the 50 % threshold of GC content. b Linear form. Different colors indicate genes in different functional groups. IR inverted repeat, LSU large subunit, SSU small subunit
