WP-MOD: A multi-omics and taxonomy database for woody plants.

Woody plants, including trees, shrubs, and woody vines, are vital components of terrestrial ecosystems and are critical for maintaining biodiversity, regulating climate, and supporting human livelihoods. Over the past decade, the accumulation of high-throughput sequencing data, multi-omics data, and taxonomic information on woody plants has increased significantly, highlighting the need for an integrative database. Here, we present the Woody Plant Multi-Omics Database (WP-MOD, https://www.woodyplant.com), a comprehensive and user-friendly platform designed to meet the growing need for specialized resources in woody plant research. The WP-MOD integrates extensive taxonomic information and multi-omics data from 373 species across 35 orders and provides a centralized resource for the analysis and exploration of woody plant biology. The database includes high-quality reference genomes and reanalyzed data from RNA sequencing, small RNA sequencing, chromatin immunoprecipitation sequencing, assay for transposase-accessible chromatin sequencing, and bisulfite sequencing, along with 17 tools for sequence and omics analysis. The WP-MOD supports both genetic and molecular research and contributes to the conservation and sustainable management of woody plants. We believe that the WP-MOD will be an essential tool for plant science researchers.
