AbstractPolyploidy is an important driving force in speciation and evolution; however, the genomic basis for parallel selection of a particular trait between polyploids and ancestral diploids remains unexplored. Here we construct graph-based pan-genomes for diploid (A2) and allotetraploid (AD1) cotton species, enabled by an assembly of 50 genomes of genetically diverse accessions.

Highlights Insights into the evolution of regulatory networks are emerging from studies of the 3D structure of chromatin and its role in transcriptional regulation. The development of regulome technologies has advanced our understanding of the evolutionary principles governing regulatory elements and chromatin organization.

AbstractPolyploidy complicates transcriptional regulation and increases phenotypic diversity in organisms. The dynamics of genetic regulation of gene expression between coresident subgenomes in polyploids remains to be understood. Here we document the genetic regulation of fiber development in allotetraploid cotton Gossypium hirsutum by sequencing 376 genomes and 2,215 time-series transcriptomes.
