Abstract The genomic basis of cladogenesis and adaptive evolutionary change has intrigued biologists for decades. unique insights from a genome-level perspective have revealed striking pattern conserved macrosynteny across huge distances in animals, yet progress many lineages been hampered by the absence data. Here, we show that origin Clitellata, clade composed most freshwater all terrestrial species phylum Annelida, coincided with an unprecedented genome-wide scrambling event resulted massive loss between marine annelids clitellates. This complete breakdown chromosome-level relationships on just one short branch is unlike any other known genome rearrangement, instead resembles chromosome shattering reassembly seen chromoanagenesis. These punctuated rearrangements included formation neocentromeres newly-acquired transposable elements, preceded further period reshaping events including whole duplications macrosyntenic reshuffling clitellate lineages, potentially triggered genes involved stability or homeostasis cell division. Notably, while these broke short-range interactions observed (including Hox), they were reformed as long-range Our study provides evidence via chromoanagenesis leading not only to new animal lineage - ‘hopeful monster’ but also changes facilitating colonisation habitats.

Sex chromosomes play an outsized role in adaptation and speciation, thus deserve particular attention evolutionary genomics. In particular, fusions between sex autosomes can produce neo-sex chromosomes, which offer important insights into the dynamics of chromosomes. Here, we investigate origin previously reported Danaus chromosome within tribe Danaini. We assembled annotated genomes Tirumala septentrionis (subtribe Danaina), Ideopsis similis (Amaurina), Idea leuconoe (Euploeina) Lycorea halia (Itunina) identified their Z-linked scaffolds. found that resulting from fusion a Z autosome corresponding to Melitaea cinxia (McChr) 21 arose common ancestor Danaina, Amaurina Euploina. also two additional as W further fused with synteny block McChr31 I. independent occurred ancestral McChr12 L. halia. tested possible sexually antagonistic selection turnover by analysing genomic distribution sex-biased genes The McChr21 involved are significantly enriched female- male-biased genes, respectively, could have hypothetically facilitated fixation This suggests sexual antagonism Lepidoptera. neo-Z both appear fully compensated somatic tissues, but extent dosage compensation for varies across tissues species.

Charles Darwin presented a unified process of diversification driven by the gradual accumulation heritable variation. The growth in DNA databases and increase genomic sequencing, combined with advances molecular phylogenetic analyses, gives us an opportunity to realize Darwin's vision, connecting generation variation lineages. rate evolution is correlated across animals plants, but relationship between genome change speciation complex: Mutation rates evolve response life history niche; substitution are influenced mutation, selection, population size; acquisition reproductive isolation vary populations; traits, niches, distribution can influence rates. connection mutation one part complex varied story speciation, which has theoretical importance for understanding biodiversity also practical impacts on use understand dynamics over macroevolutionary timescales.

Abstract The evolutionary impact of structural variants, such as chromosomal inversions, is well documented, especially for their role in local adaptation high gene flow systems. However, the other genomic rearrangements like fusions, fissions, and translocations still relatively unexplored. Here we present six chromosome-level Gadid reference genomes non-migratory Atlantic cod ( Gadus morhua ) i.e., Norwegian coastal (NCC), haddock (Melanogrammus aeglefinus), burbot Lota lota ), European hake Merluccius merluccius two keystone Arctic codfishes: polar Boreogadus saida Arctogadus glacialis ). Within a comparative genomics framework, uncovered several lineage-specific resulting reduced number chromosomes compared to ancestral state cold-water adapted codfishes. identified fusions were not homologous, indicating that they originate from independent events. Additionally, partly overlapping inversions between species detected. Using smaller population dataset, degree conservation some (including breakpoint regions), suggesting these regions are under selection, potentially importance. With use genome assemblies, demonstrate how large reorganizations likely play important roles speciation processes thus, particular freezing environmental conditions. Moreover, observe massive rearrangement events can take place across short time scales.

Abstract Research on supergenes, non‐recombining genomic regions housing tightly linked genes that control complex phenotypes, has recently gained prominence in genomics. Heterostyly, a floral heteromorphism promoting outcrossing several angiosperm families, is controlled by the S ‐locus supergene. The been studied primarily closely related Primula species and, more recently, other groups independently evolved heterostyly. However, it remains unknown whether genetic architecture and composition of are maintained among share common origin heterostyly subsequently diverged across larger time scales. To address this research gap, we present chromosome‐scale genome assembly edelbergii , shares same with veris (whose characterized) but from 18 million years ago. Comparative analyses between these two allowed us to show, for first time, can ‘jump’ (i.e. translocate) chromosomes maintaining its function controlling Additionally, found four were conserved reshuffled within supergene, seemingly without affecting their expression, thus could not detect changes explaining lack self‐incompatibility P. . Furthermore, confirmed undergoing degeneration. Finally, investigated evolutionary history Ericales terms whole duplications transposable element accumulation. In summary, our work provides valuable resource comparative aimed at investigating genetics pivotal role supergenes shaping evolution phenotypes.

Sex chromosomes can expand through fusion with autosomes, thereby acquiring unique evolutionary patterns. In butterflies and moths (Lepidoptera), these sex chromosome–autosome (SA) fusions occur relatively frequently, suggesting possible advantages. Here, we investigated how SA affects chromosome features molecular evolution in leafroller (Lepidoptera: Tortricidae). Phylogenomic analysis showed that Tortricidae diverged ∼124 million years ago, accompanied by an between the Merian elements M(20 + 17) MZ. contrast to partial autosomal fusions, fused neo-Z Chromosome developed a hierarchical architecture, which three exhibit heterogeneous sequence Specifically, M17 part had distinct base composition chromatin domains. Unlike M20 MZ, was expressed at same levels as autosomes both sexes, compensating for lost gene dosage females. Concurrently, drove hotspot, accelerating of several genes related ecological adaptation (e.g., ABCC s) facilitating divergence closely species, whereas undercompensated did not show such effect. Thus, accelerated under novel pattern compensation may have favored adaptive radiation this group. This study demonstrates association karyotype variant explains recurrent Lepidoptera.

Summary Karyotype changes are a formidable evolutionary force by directly impacting cross‐incompatibility, gene dosage, genetic linkage, chromosome segregation, and meiotic recombination landscape. These often arise spontaneously commonly detected within plant lineages, even between closely related accessions. One element that can influence drastic karyotype after only one (or few) generations is the alteration of centromere position, number, distribution, or its strength. Here, we briefly explore how these different configurations result in rearrangements, reproduction recombination.
