The multi-scale complexity of human genetic variation beyond continental groups.

Traditional clustering and visualization approaches in human genetics often operate under frameworks that assume inherent, discrete groupings. These methods can inadvertently simplify multifaceted relationships, functioning to entrench the idea of typological groups. We introduce a network-based pipeline and visualization tool grounded in relational thinking, which constructs networks from a variety of genetic similarity metrics.

Allopolyploidy expanded gene content but not pangenomic variation in the hexaploid oilseed Camelina sativa.

Ancient whole-genome duplications are believed to facilitate novelty and adaptation by providing the raw fuel for new genes. However, it is unclear how recent whole-genome duplications may contribute to evolvability within recent polyploids. Hybridization accompanying some whole-genome duplications may combine divergent gene content among diploid species.

The genome sequence of the Atlantic mackerel, Linnaeus, 1758.

We present a genome assembly from an individual (the Atlantic mackerel; Chordata; Actinopteri; Scombriformes; Scombridae). The genome sequence has a total length of 764.10 megabases.

Exploring genetic diversity, population structure, and subgenome differences in the allopolyploid : implications for future breeding and research studies.

Camelina (), an allohexaploid species, is an emerging aviation biofuel crop that has been the focus of resurgent interest in recent decades. To guide future breeding and crop improvement efforts, the community requires a deeper comprehension of subgenome dominance, often noted in allopolyploid species, "alongside an understanding of the genetic diversity" and population structure of material present within breeding programs. We conducted population genetic analyses of a diversity panel, leveraging a new genome, to estimate nucleotide diversity and population structure, and analyzed for patterns of subgenome expression dominance among different organs.

Depth-dependent bacterial colonization on model chitin particles in the open ocean.

Sinking particles transport carbon from the surface to the deep ocean. Microbial colonization and remineralization are important ecosystem services constraining ocean biogeochemistry by recycling and redistributing nutrients from the surface to the deep ocean. Fragmentation of particles by zooplankton and the resulting colonization by microorganisms before ingestion, known as 'microbial gardening', allows for trophic upgrading and increased microbial biomass for detritivorous zooplankton.
