Customize and get the most out of your reduced-representation sequencing experiment with the new simulation software RADinitio

Marvin Choquet

Summary: Whole-genome sequencing remains difficult, costly, and time-consuming, but the emergence of genome reduced-representation sequencing protocols like RADseq has provided access to genome-wide information. The new software RADinitio allows for simulation of RADseq data and precise identification of failure sources in designing RADseq experiments. This advancement in RADseq data simulation is likely to improve success in RADseq experiments.

The genome of Draba nivalis shows signatures of adaptation to the extreme environmental stresses of the Arctic

Michael D. Nowak et al.

Summary: The research team completed the chromosome-scale genome assembly of the plant Draba nivalis adapted to the harsh Arctic environment, revealing expanded gene families associated with drought and cold stress, possibly driven by transposable elements. Tests of positive selection identified candidate genes associated with meiosis, photoperiodism, cold, drought, and oxidative stress responses.

Reference genome and demographic history of the most endangered marine mammal, the vaquita

Phillip A. Morin et al.

Summary: The vaquita is the most critically endangered marine mammal, with fewer than 19 remaining in the wild. Research has shown that its genome has a stable historical population size and low heterozygosity, potentially allowing for the purging of highly deleterious alleles and maintaining the necessary diversity for population health.

A chromosome level genome assembly of Propsilocerus akamusi to understand its response to heavy metal exposure

Xiaoya Sun et al.

Summary: Chironomidae species are commonly used in studying pollutants in aquatic systems, with the nonbiting midge Propsilocerus akamusi being a suitable bioindicator for metal stress in urban streams. The first chromosome-level genome of P. akamusi was sequenced, revealing an expansion of haemoglobin genes and potential role in copper tolerance. The high-quality genome assembly and transcriptomic analyses provide new insights into the molecular mechanisms of heavy metal stress, offering valuable resources for understanding the evolutionary history, genetics, and ecology of this species and other midges.
