# PPGV: a comprehensive database of peach population genome variation

## TL;DR

PPGV is a new database that compiles peach genome data and variation information from 1,378 samples to support genetic research and breeding.

## Contribution

The novel contribution is the creation of a comprehensive peach genome variation database with integrated tools for data analysis and breeding assistance.

## Key findings

- PPGV includes 10 peach genome datasets and variation data from 1,378 samples.
- The database offers tools like BLAST, gene ID conversion, and enrichment analysis for functional studies.
- Resequencing data was aligned with three high-quality reference genomes for mutation detection.

## Abstract

Peach tree is one of the most important fruit trees in the world, and it has been cultivated for more than 7,500 years. In recent years, the genome and population resequencing of peach trees have been published continuously, which has effectively promoted the research of peach tree genetics and breeding. In order to promote the further mining and utilization of these data, we integrated and constructed a comprehensive peach genome and variation database (PPGV, http://peachtree.work/home). The PPGV contains 10 sets of published peach tree genome data, as well as genomic variation information for 1,378 peach tree samples (the resequencing data of 1,378 samples were aligned with the high-quality genomes of Lovell, CN14 and Chinesecling, respectively, for mutation detection). A variety of useful and flexible tools, such as BLAST, Gene ID Convert, KEGG/GO Enrichment, Primer Design and Gene function, were also specially designed for searching data and assisting in breeding.
