Project description:Phylogenomic discordance is driven by wide-spread introgression and incomplete lineage sorting during rapid species diversification within rattlesnakes (Viperidae: Crotalus and Sistrurus)
Project description:Developmental gene function is conserved over deep time, but similar cis-regulatory sequence conservation is rarely found. However, rapid sequence turnover, paleopolyploidy, structural variation, and limited phylogenomic sampling have impeded conserved non-coding sequence (CNS) discovery. Using Conservatory, an algorithm that leverages microsynteny and iterative alignments to map CNS-gene associations over evolution, we uncovered ~2.3M CNSs, including over 3,000 predating angiosperms, from 284 plant species spanning 400 million years of diversification. Ancient CNSs were enriched near developmental regulators, and mutagenizing those near HOMEOBOX genes produced strong phenotypes. Tracing CNS evolution uncovered key principles: CNS spacing varies, but order is conserved; genomic rearrangements form new CNS-gene associations; and ancient CNSs are preferentially retained among paralogs but often are lost as cohorts or evolve into lineage-specific CNSs.

Project description:Phylogenomics of a genus of Great Speciators reveals rampant incomplete lineage sorting, gene flow, and mitochondrial capture in island systems
Project description:Phylogenomic Discordance in the Eared Seals is best explained by Incomplete Lineage Sorting following Explosive Radiation in the Southern Hemisphere
Project description:Extensive genome-wide phylogenetic discordance is due to incomplete lineage sorting and not ongoing introgression in a rapidly radiated bryophyte genus
Project description:Bryophytes comprise mosses, liverworts and hornworts. The chromatin landscapes of mosses and liverworts are different, leaving open the question regarding the identity of the chromatin landscape of all bryophytes. To address this question we obtained a genome wide profile of 5-methylated cytosine from a model hornwort, Anthoceros agrestis.
