Comparative analysis shows high level of lineage sorting in genomic regions with low recombination in the extended Picea likiangensis species complex.

•Phylogenomic analysis uncovers widespread discordance in the extended Picea likiangensis complex.•Introgression (54.99%) and incomplete lineage sorting (ILS; 33.12%) are key drivers of this incongruity.•Recombination rates shape ILS and introgression, with high rates correlating with elevated levels.•Genes linked to abiotic stress responses exhibit significant introgression and ILS, suggesting adaptive evolution.•Lower recombination rates improve accuracy in species relationships.

期刊介绍： Plant Diversity (formerly Plant Diversity and Resources) is an international plant science journal that publishes substantial original research and review papers that advance our understanding of the past and current distribution of plants, contribute to the development of more phylogenetically accurate taxonomic classifications, present new findings on or insights into evolutionary processes and mechanisms that are of interest to the community of plant systematic and evolutionary biologists. While the focus of the journal is on biodiversity, ecology and evolution of East Asian flora, it is not limited to these topics. Applied evolutionary issues, such as climate change and conservation biology, are welcome, especially if they address conceptual problems. Theoretical papers are equally welcome. Preference is given to concise, clearly written papers focusing on precisely framed questions or hypotheses. Papers that are purely descriptive have a low chance of acceptance. Fields covered by the journal include: plant systematics and taxonomy- evolutionary developmental biology- reproductive biology- phylo- and biogeography- evolutionary ecology- population biology- conservation biology- palaeobotany- molecular evolution- comparative and evolutionary genomics- physiology- biochemistry
