Fig. 1From: Comparative chloroplast genome analyses of Amomum: insights into evolutionary history and species identificationChloroplast (cp) genome maps of A. villosum, A. longipetiolatum and A. maximum. Genes inside the circle are transcribed clockwise, and those outside are transcribed counter-clockwise. Genes in different functional groups are color-coded. The small (SSC) and large (LSC) single copy regions and inverted repeat (IRa and IRb) regions are noted in the inner circleBack to article page
