Summary
The Plant Promoter Database (ppdb) annotates Arabidopsis and rice promoters using species-specific elements and local distribution of short sequences (LDSS) for detailed structural analysis.
Area of Science:
- Genomics
- Bioinformatics
- Plant Biology
Background:
- Plant promoter annotation is crucial for understanding gene regulation.
- Existing databases may lack species-specific promoter element details.
- Transcription start site (TSS) data is essential for precise promoter mapping.
Purpose of the Study:
- To introduce the Plant Promoter Database (ppdb) as a comprehensive resource for plant promoter analysis.
- To provide detailed annotation of Arabidopsis and rice promoters.
- To facilitate the identification of core promoter structures and regulatory elements.
Main Methods:
- Utilizing a position-sensitive extraction method, local distribution of short sequences (LDSS), to identify promoter elements.
- Integrating full-length cDNA clone data and extensive TSS tag data.
- Developing species-specific sets of promoter elements for enhanced accuracy.
Main Results:
- ppdb offers detailed promoter structure information for Arabidopsis and rice.
- The database identifies core promoter regions, regulatory elements, and TSS clusters.
- Species-specific promoter element sets improve the analysis of promoter architecture.
Conclusions:
- ppdb provides a valuable, species-specific resource for plant promoter research.
- The database aids in understanding plant gene regulation through detailed promoter annotation.
- Enhanced identification of promoter elements and TSS distribution is achievable with ppdb.

02:40The Eukaryotic Promoter Region
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences. The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...
01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
01:25Cell Signaling in Plants
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
