syntenyPlotteR: a user-friendly R package to visualize genome synteny, ideal for both experienced and novice bioinformaticians

MOTIVATION: The rapid increase in the number of chromosome-scale genome assemblies has renewed interest in chromosome evolution studies. The visualization of syntenic relationships between genomes is a crucial initial step in the study of chromosome rearrangements and evolution. There are few tools available that serve this purpose, and they can be difficult to learn. Moreover, these tools are limited in the number of species comparisons that can be visualized and the size of chromosome rearrangements identified. Thus, the development of novel visualization tools is in strong need. RESULTS: Here, we present syntenyPlotteR, an R package developed to visualize homologous synteny blocks in a pairwise or multispecies manner. This package contains three functions that allow users to generate publication-quality representations of syntenic relationships easily and quickly between genomes of interest. AVAILABILITY AND IMPLEMENTATION: SyntenyPlotteR can be installed from CRAN with the documentation found in https://farre-lab.github.io/syntenyPlotteR/.
