Description
Fernando Cruz and colleagues present an improved chromosome-level genome assembly for the jaguar, in a 2026 data description. Jaguar numbers have fallen with habitat loss across the Americas, and conservation work depends on a reliable reference genome. Earlier assemblies were more fragmented. The team sequenced two animals with long-read and short-read methods, then used chromosome contact data to order the pieces.
Nearly all of the assembled sequence landed on chromosomes, and the team annotated more than twenty-five thousand protein-coding genes. Contiguity improved markedly over the existing reference. The authors position the new assembly, named mPanOnc3.5, as a firmer base for tracking jaguar populations, comparing individuals, and studying how this big cat evolved. Such a resource also helps planners judge genetic health when designing protection programs.
