The Visayan Warty Pig (Sus cebifrons) Genome Provides Insight Into Chromosome Evolution and Sensory Adaptation in Pigs.

ABSTRACT: It is largely unknown how mammalian genomes evolve under rapid speciation and environmental adaptation. An excellent model for understanding fast evolution is provided by the genus Sus, which diverged relatively recently and lacks postzygotic isolation. Here, we present a high-quality reference genome of the Visayan warty pig, which is specialized to a tropical island environment. Comparing the genome sequences and chromatin contact maps of the Visayan warty pig (Sus cebifrons) and domestic pig (Sus scrofa), we characterized the dynamics of chromosomal structure evolution during Sus speciation, revealing the similar chromosome conformation as the potential biological mechanism of frequent postdivergence hybridization among Suidae. We further investigated the different signatures of adaptiv
