A new database, PlnTFDB, offers comprehensive plant transcription factor sets for five species. This resource aids in understanding plant gene regulation and designing improved plant biomass through cross-species TF analysis.
Area of Science:
- Plant molecular biology
- Genomics
- Bioinformatics
Background:
- Transcription factors (TFs) are crucial regulatory proteins controlling gene expression in plants.
- TFs play vital roles in plant development, stress responses, and evolution.
- A gap exists in accessible, comprehensive TF data for sequenced plant genomes.
Purpose of the Study:
- To create a centralized, web-accessible database of plant transcription factors.
- To provide comprehensive TF sets for multiple plant species.
- To facilitate cross-species TF analysis for plant biomass improvement.
Main Methods:
- Developed PlnTFDB, an integrative plant TF database.
- Included TF data for *Arabidopsis thaliana*, *Populus trichocarpa*, *Oryza sativa*, *Chlamydomonas reinhardtii*, and *Ostreococcus tauri*.
- Provided access to protein sequences, genomic data, and domain architecture.
Main Results:
- Curated putatively complete sets of TFs for five plant genomes.
- Established PlnTFDB with a user-friendly web interface.
- Integrated daughter databases for species-specific TF exploration.
Conclusions:
- PlnTFDB provides a valuable resource for plant TF research.
- The database enables efficient access to TF information for multiple species.
- Future updates will incorporate data from newly sequenced plant genomes.

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
