Phylogenetic trees serve as a fundamental tool for understanding plant classification and identification, providing a clear depiction of evolutionary relationships between species. The construction of precise phylogenetic trees is not only computationally intensive but also demands the dedicated effort of researchers. Despite these challenges, there is still a significant hurdle in making these resources accessible for easy retrieval, communication, and display to the public. Our research synthesized data from existing phylogenetic tree databases, academic literature, and research datasets, employing advanced methods such as Python programming and LLM models for data cleaning and integration. We meticulously identified taxonomic groups and specific species associated with each tree, culminating in a compilation of 385,143 phylogenetic trees from 10,011 phylogenetic research papers. Each entry includes detailed information and access links to the original papers, metadata of phylogenetic trees, and storage in various formats such as Newick, Nexus, and PhyloXML. Building upon this foundation, we developed the PlantTreeDB website. This platform delivers a multi-keyword, rapid, and user-friendly phylogenetic tree search service, including fuzzy searches for taxonomic groups, and supports a variety of visualization and editing methods. PlantTreeDB allows for bulk data download and submission, with specialized optimization for plant group data retrieval and submission to ensure accuracy. PlantTreeDB is set to significantly foster the sharing and exchange of plant phylogenetic data, thereby providing a substantial impetus to the advancement of research in plant evolution and systematics.
