The International Crocodilian Genomes Working Group (ICGWG) originally lead a large-scale effort to examine crocodilian biology by targeting the American alligator (Alligator mississippiensis), saltwater crocodile (Crocodylus porosus), and gharial (Gavialis gangeticus) for genome sequencing.
Those efforts also involved the collection of related data that can be used to enrich our knowledge of crocodilian genomes. These data included:
- Transcriptome data for various tissues
- BAC-end sequences for all three taxa (and some complete BAC sequences)
Initial efforts concluded in late 2014 with the publication of all three genomes in Science. Multiple satellite publications have also resulted from this work.
Current efforts focus on generating reference-based and de novo assemblies for many of the remaining 20+ species of extant crocodilians.
