AI Article Synopsis

  • The text discusses the importance of chromosome number in understanding species genomes but highlights the challenges in studying its evolution due to limited access to karyotype data.
  • It introduces a new curated database (karyotype.org) designed to provide easy access to chromosome number and sex chromosome system data specifically for amphibians.
  • The database features an open web interface that allows users to create custom plots and tables, as well as download data for further analysis.

Article Abstract

One of the first characteristics that we learn about the genome of many species is the number of chromosomes it is divided among. Despite this, many questions regarding the evolution of chromosome number remain unanswered. Testing hypotheses of chromosome number evolution using comparative approaches requires trait data to be readily accessible and associated with currently accepted taxonomy. The lack of accessible karyotype data that can be linked to phylogenies has limited the application of comparative approaches that could help us understand the evolution of genome structure. Furthermore, for taxonomists, the significance of new karyotype data can only be determined with reference to records for other species. Here, we describe a curated database (karyotype.org) developed to facilitate access to chromosome number and sex chromosome system data for amphibians. The open web interface for this database allows users to generate customized exploratory plots and tables of selected clades, as well as downloading CSV files for offline analyses.
