Plant Transcription Factor Database

Species included in PlantTFDB 4.0 covers the main lineages of green plants. Therefore, PlantTFDB provides genomic TF repertoires across Viridiplantae. To provide comprehensive information for the TF family, a brief introduction and key references are presented for each family. Comprehensive annotations are made for each identified TF, including functional domains, 3D structures, gene ontology (GO), plant ontology (PO), expression information, expert-curated functional description, regulation information, interaction, conserved elements, references, and annotations in various databases such as UniProt, RefSeq, TransFac, STRING, and VISTA. By inferring orthologous groups and constructing phylogenetic trees, evolutionary relationships among identified TFs were inferred. In addition, PlantTFDB has a simple and user-friendly interface to allow users to query based on combined conditions or make sequence similarity search using BLAST. The new version PlantTFDB 5.0 has been incorporated into PlantRegMap http://plantregmap.gao-lab.org/.

PlantTFDB 4.0 所涵盖的物种囊括了绿色植物的各大进化谱系。因此，PlantTFDB 为维管植物类群提供了全面的转录因子基因组资源。为全面介绍转录因子家族，对每个家族均进行了简要介绍及关键文献的引用。对每个已识别的转录因子进行了详尽的注释，包括功能域、三维结构、基因本体（GO）、植物本体（PO）、表达信息、专家审核的功能描述、调控信息、相互作用、保守元件、参考文献以及在 UniProt、RefSeq、TransFac、STRING 和 VISTA 等数据库中的注释。通过推断同源群组并构建系统发育树，推断出已识别转录因子之间的进化关系。此外，PlantTFDB 还具备简洁且易于使用的用户界面，用户可基于组合条件进行查询，或使用 BLAST 进行序列相似性搜索。新版本 PlantTFDB 5.0 已整合至 PlantRegMap（http://plantregmap.gao-lab.org/）。
