agReg-SNPdb-Plants

agReg-SNPdb-Plants catalogs regulatory single nucleotide polymorphisms (rSNPs) in promoter regions of 13 agriculturally important plant species and predicts their effects on transcription factor binding to support interpretation of GWAS and regulatory genomics.

Key Features:

• Extensive Species Coverage: agReg-SNPdb-Plants includes data for 13 plant species and subspecies: Brassica napus, Helianthus annuus, Hordeum vulgare, Oryza glaberrima, Oryza glumipatula, Oryza sativa Indica, Oryza sativa Japonica, Solanum lycopersicum, Sorghum bicolor, Triticum aestivum, Triticum turgidum, Vitis vinifera, and Zea mays.
• Promoter-region rSNP Annotation: SNPs are mapped to gene promoter regions and annotated as regulatory SNPs (rSNPs) affecting potential transcription factor interactions.
• Predicted Impact on Transcription Factor Binding: The database provides predictions of how each rSNP alters transcription factor binding sites (TFBSs) and DNA affinity for transcription factors.

Scientific Applications:

• GWAS Interpretation: Identification of rSNPs and their predicted effects on TF binding aids in pinpointing biologically causative variants underlying trait-associated loci from GWAS.
• Functional Genomics: The rSNP annotations and TFBS impact predictions support studies of gene regulation mechanisms and the identification of regulatory elements involved in development and stress responses.
• Plant Breeding and Genetic Improvement: Information on rSNPs and predicted regulatory effects can be used to prioritize variants for breeding programs targeting yield, disease resistance, or environmental adaptability.

Methodology:

Predictions are generated by computational models and algorithms that analyze promoter sequence data and by bioinformatics tools assessing changes in DNA affinity for transcription factors, integrating empirical data.
