Circular chloroplast (CP) genome map of Stephania tetrandra. Genes drawn outside the circle are transcribed anti-clockwise, while those inside the circle are transcribed clockwise. Large single copy (LSC) region, inverted repeat (IRA, IRB) regions and small single copy (SSC) region are shown in the figure. The darker gray in the inner circle corresponds GC content whereas the lighter gray corresponds AT content. Different colors of genes represent their different functions
