Chloroplast phylogeny of 38 Rubus species using maximum likelihood (ML) method based on the concatenated LSC, SSC and an IR region. The red fonts represent R. idaeus in this study. Two Rosa species (Rosa sertata and Rosa glomerata) were selected as outgroups. Genbank IDs were listed after the species’ names. Maximum likelihood bootstrap values (BS) are shown at nodes. Branches with no values listed have 100% BS. The following sequences were used: Rubus parvifolius OK127884 (Yu et al. ), Rubus innominatus OK127883 (Yu et al. ), Rubus niveus NC056930, Rubus biflorus NC080344, Rubus phoenicolasius MW115432 (Zhang et al. ), Rubus pileatus NC056947, Rubus irritans NC057600 (Han et al. ), Rubus amabilis NC047211, Rubus sachalinensis NC056965 (Liu et al. ), Rubus idaeus OR698909 (this study), Rubus corchorifolius NC056942, Rubus chingii NC050296 (Wang et al. ), Rubus trianthus NC060616 (Yu et al. ), Rubus hirsutus OK127882 (Yu et al. ), Rubus tsangii NC056940, Rubus rosifolius OL435124 (Yang et al. ), Rubus crataegifolius NC039704 (Yang et al. ), Rubus peltatus NC056937, Rubus xanthocarpus NC056938, Rubus leucanthus MK105853, Rubus columellaris NC056932, Rubus ellipticus NC056929, Rubus wallichianus NC056933, Rubus rufus NC056798, Rubus cochinchinensis NC056289, Rubus pacificus NC064142 (Xiong et al. ), Rubus ichangensis NC056935, Rubus lambertianus OK127886 (Yu et al. ), Rubus buergeri NC072261, Rubus hunanensis OK127885 (Yu et al. ), Rubus tephrodes NC060615 (Yu et al. ), Rubus swinhoei OQ411240, Rubus bambusarum NC056916, Rubus henryi NC056945, Rubus setchuenensis NC056946, Rubus lineatus NC056943, Rubus pentagonus NC056936, Rubus quinquefoliolatus NC063615, Rosa sertata NC066975, Rosa glomerata NC062462 (Chen et al. ).
