Fig. 2From: Phylogenomic and comparative analyses of Coffeeae alliance (Rubiaceae): deep insights into phylogenetic relationships and plastome evolutionObserved negligible ndhF genes shift of IRB/SSC boundaries of representative chloroplast genomes of the Coffeeae alliance tribes. The IR, LSC, and IR border regions of chloroplast genomes for Coffeeae alliance tribe are indicated. Numbers below and above the gene indicate a gap between gene ends and boundary site in base lengths (bp). The genes are denoted by colored boxesBack to article page
