PlantTFDB
Plant Transcriptional Regulatory Map




Introduction
Systematical identification of transcription factors (TFs), regulatory elements and interactions between them is essential for investigating the functional mechanisms and evolution of transcriptional regulatory systems. With the aim to provide a comprehensive, high-quality resource for the study of transcriptional regulation in plants, we developed PlantRegMap. It includes TF repertoires and comprehensive annotation, multiple types of regulatory elements and genome-wide regulatory interactions derived from literature, high-throughput assays and/or genome comparison, as well as the architectures and evolutionary features of plant transcription regulatory systems. To take full advantage of our enrich data and pipelines, we set up multiple webservers for TF identification, regulation prediction and functional enrichment analyses. We wish our data and tools can promote users to explore the functional mechanisms and evolutionary features of plant transcriptional regulatory system.
What's new

  Update in July 2019

  1. Updated annotations for the TFs of 165 species in TF knowledge base.
  2. Set up a module "extended TF repertoires" (TFext) to release the TF repertoires of newly sequenced species in time.
  3. Established the genome-wide, base-resolution conservation landscapes (conserved elements, PhastCons and PhyloP scores) based on the whole genome alignments for 63 plants in seven lineages, covering main lineages of angiosperms (download), and set up a genome browser for users to navigate them (cis-map).
  4. Developed a new algorithm (FunTFBS) to screen for functional TF binding sites by employing the evolutionary footprints from base-varied binding affinities of TFs. The assessment showed that our algorithm is significantly superior to existing methods in accuracy.
  5. Using FunTFBS and the conservation landscapes established above, we further identified over 21,997,501 million functional TFBSs (download) and 2,196,397 regulatory interactions (download), charting the functional regulatory maps for the 63 plants for the first time.
  6. Updated the set of tools for transcriptional regulatory analyses using the newly released algorithm and resources (Regulation Prediction / TF Enrichment).
