Ding Yamei, Associate Researcher at the South China Botanical Garden, Chinese Academy of Sciences, has long been dedicated to studying the role of hybridization and introgression in plant speciation and adaptation. She systematically integrates multi-omics data, identifies adaptive introgression signals, and resolves complex phylogenetic relationships, achieving significant breakthroughs. Her related work has been published in prestigious international journals such as Nature Communications and Genome Biology.

By employing methods from population genomics, comparative genomics, and phylogenetic genomics, she systematically analyzes the impact of gene flow on genetic differentiation, species boundary maintenance, and adaptive evolution across multiple scales. Her research elucidates how cultivated walnuts (Juglans regia) facilitate the domestication of wild relatives through introgression, offering new insights into the domestication of perennial plants.

Against the backdrop of ancient polyploidization and gene flow, she optimizes subgenome partitioning and data processing, combining phylogenetic methods to precisely reconstruct the evolutionary relationships of complex polyploid species. This provides methodological support for robust inference of polyploid phylogeny and reveals their complex evolutionary history.

Using the fig-fig wasp obligate mutualistic system as a model, she systematically analyzes the role of persistent gene flow in speciation and adaptive evolution, while also evaluating the system's response and adaptive potential under future environmental changes. Her research findings provide a scientific basis for plant resource conservation, tree breeding, and high-quality germplasm resource management.
