PERSEUS: an interactive and intuitive web-based tool for pedigree visualization

Area of Science:

• Genetics and Bioinformatics
• Plant Breeding
• Evolutionary Biology

Background:

• Pedigree-based analyses are crucial for understanding genetic relationships in breeding programs.
• Current lineage visualization tools are limited for public display, exploration, and trait tracing.
• Decoding inherited traits and genotypic variability is key for genomic selection.

Purpose of the Study:

• To introduce PERSEUS, a user-friendly, interactive web-based tool for pedigree visualization.
• To overcome limitations of existing lineage visualization methods.
• To facilitate exploration of phenotypic traits along pedigrees.

Main Methods:

• PERSEUS utilizes directed graph networks with a force-repulsion layout for visualization.
• The tool is web-based, ensuring user-friendliness and accessibility.
• It allows seamless searching and downloading of phenotypic traits.

Main Results:

• PERSEUS provides intuitive and interactive pedigree visualizations.
• The tool showcases individual relationships among accessions effectively.
• Phenotypic traits can be easily searched and downloaded along the pedigrees.

Conclusions:

• PERSEUS is a valuable tool for breeders and scientists.
• It enhances evolutionary, genealogy, and diversity analyses.
• The tool offers improved exploration of genetic relationships and traits.
