The phylogenetic tree with bootstrap support (BS) values was inferred from the ML analysis based on 30 cp genome sequences. The blue module and purple module represent the tribe Senecioneae and tribe Anthemideae (outgroup), respectively. The whole phylogenetic clade of Sinosenecio is marked with red, and the phylogenetic position of Sinosenecio globigerus is highlighted by the red star. Genbank number is given after each species name. The cp genome sequences used for phylogenetic analysis were all referenced and derived from Liu et al. (2023) study, as follows: Ligularia fischeri 729822, Ligularia jaluensis MF539931, Ligularia intermedia MF539930, Parasenecio latipes ON749759, Parasenecio palmatisectus ON749760, Sinosenecio globigerus OR752442, Sinosenecio albonervius OL678114, Sinosenecio baojingensis MZ325394 Sinosenecio jishouensis MT876597, Sinosenecio oldhamianus MN013404, Petasites fragrans LC735682, Petasites japonicus LC735683, Petasites tatewakianus LC735685, Roldana aschenborniana MK170177, Roldana barba-johannis MK170178, telanthophora grandifolia MK170179, arnoglossum atriplicifolium MK170176, Gynoxys asterotricha MK044798, Gynoxys megacephala MN328892, Gynoxys mandonii MK056106, Dendrosenecio battiscombei MK756016/MK756031, Dendrosenecio elgonensis MK756018, Dendrosenecio brassiciformis MK756022, Senecio keniophytum MH483946, Senecio vulgaris MK654722, Senecio roseiflorus MH483948, crassocephalum crepidioides MW362305, Chrysanthemum indicum MW633069, Soliva sessilis KX063863.

... The plastid genomes of diverse plant taxa exhibit fine collinearity for comparative analysis, while genomic variation is also important for unraveling large-scale evolution (Zhang and Li 2011;Wang et al. 2023). In recent years, as more and more plastid genomes from species of the S. oldhamianus group were published Zhou et al. 2021;Xie et al. 2022;Wang et al. 2024), a foundation has been laid for the study of the genetic structure and genetic diversity of plastomes in the genus. In this context, we newly report the plastid genome of S. eriopodus C. Jeffrey & Y. L. Chen (1984), a member from the Sinosenecio s.s. ...
... The S. eriopodus plastome was structurally similar to that of other Sinosenecio species and was more consistent in terms of gene counts Zhou et al. 2021;Xie et al. 2022;Wang et al. 2024), suggesting that the plastid genomes of species in this genus were highly conserved. We reconstructed the phylogeny of Sinosenecio based on the whole plastid genome sequence and determined the S. eriopodus phylogenetic position. ...
... We reconstructed the phylogeny of Sinosenecio based on the whole plastid genome sequence and determined the S. eriopodus phylogenetic position. Compared with prior phylogenomics that sampled exclusively within the S. oldhamianus group Zhou et al. 2021;Xie et al. 2022;Wang et al. 2024), the present study reaffirmed the polyphyly of Sinosenecio. The relationships among the five species of the S. oldhamianus group have been supported in previous studies (Zou et al. 2020;Wang et al. 2024), and this group was closely related to some genera of the subtribe Tephroseridinae (such as Nemosenecio and Tephroseris) (Liu 2010;Zou et al. 2020). ...
The genus Sinosenecio B. Nordenstam (1978) is a challenging taxonomic group with complex infrageneric relationships. Here, we newly report the plastid genome of S. eriopodus (Cumm.) C. Jeffrey & Y. L. Chen (1984). Whole genome exhibited a typical quadratic structure with a total size of 151,212 bp and 132 genes. We revealed for the first time that the matK and rpoA were positively selected genes within Sinosenecio. Phylogenetic reconstruction based on whole plastid genome sequences indicated that S. eriopodus was not clustered into a monophyletic clade with members belonging to the S. oldhamianus group of Sinosenecio but rather was closely related to some genera in the subtribe Tussilaginae s.s. of Asteraceae.
