  1. ...-reserved 3D architecture of A. avenae. (A) Hi-C heat map of two haplotype sets of A. avenae; from top to bottom are nine pairs of homologous chromosomes 1–9. (B) Circos plot (Krzywinski et al. 2009) of A. avenae haplotype-resolved T2T genomic features. I: The collinearity between two sets of haplotypes; II...
  2. ...the significance of fast-evolving ubiquitination and protein degradation pathways in driving genomic divergence, and suggest a potential link between incompatible immunity and speciation.Genomes undergo continuous variations, thereby enabling organisms to adapt to dynamic shifts in both extrinsic and intrinsic...
  3. ...Barcelona, Spain Corresponding authors: claudia.carareto@unesp.br, cristina.vieira@univ.lyon1.frAbstractHost shifts in insects are considered a key process with the potential to contribute to reproductive isolation and speciation. Both genomic and transcriptomic variation are attributed to such a process...
  4. ...this study, we present two new chromosomal-level assemblies for the alligator gar (Atractosteus spatula) and longnose gar (Lepisosteus osseus) to investigate the dynamics of genomic structural and sequence evolution in living fossils. Our objectives are to (1) characterize the chromosome evolution...
  5. ...increased, opening exciting new avenues for studying human evolution. Here, we review recent methodological advances in the study of archaic introgression. We begin by providing an overview of the genealogical and genomic signatures left behind by introgression events before reviewing recent methods...

  7. ...of this group. This study demonstrates the association between a karyotype variant and adaptive evolution and explains the recurrent SA fusion in the Lepidoptera.Large-scale chromosomal rearrangements such as fusions may promote ecological adaptation and speciation (Guerrero and Kirkpatrick 2014; Lucek et al...
  8. ...and the development of key agronomic traits in crops (Willson 2020). Comparative genomics studies have demonstrated that speciation often involves chromosome karyotype changes, such as chromosome end fusions or the insertion of one chromosome near another's centromere (Mandáková et al. 2020; Lysak 2022). Chromosomes...
  9. ...DNA fraction, we performed two-dimensional (2D) agarose gel electrophoresis of total genomic DNA, followed by Southern blotting with specific probes (Fig. 7A). Besides signals from linear chromosomal DNA, both satellites appeared at arc positions, confirming their presence in the eccDNAs. Another potential...
  10. ...@tamu.edu, jje@uci.eduAbstractMany essential functions of organisms are encoded in highly repetitive genomic regions, including histones involved in DNA packaging, centromeres that are core components of chromosome segregation, ribosomal RNA comprising the protein translation machinery, telomeres that ensure...
