The Multi-Synteny Viewer is an interactive visualization tool designed for exploring syntenic relationships across multiple genomes simultaneously. It enables researchers to identify conserved genomic regions, track chromosomal rearrangements, and analyze large-scale evolutionary patterns across diverse plant species. With support for dynamic filtering, comparative analysis, and exportable visual outputs, this tool facilitates in-depth investigation of genome structure, duplication events, and lineage-specific adaptations across extensive genomic datasets.
