Phylogenetic relationship of ADS protein sequences of A. annua and its Homologous of related species. This phylogenetic tree uses the ML method, and the different colored circular dots of each node in the phylogenetic tree indicate different sizes of bootstrap, gray indicates ≤ 50, yellow indicates 51 ~ 80, and red indicates 81 ~ 100. Different colored shapes in front of the leaf labels indicate different species, please see the illustration for details
