Article Synopsis
- Pteronarcys californica, also known as the giant salmonfly, is the largest stonefly species in the western U.S., but its populations have significantly declined and are locally extinct in many rivers, especially in Utah, Colorado, and Montana.
- Previous studies have looked at ecological conditions for its survival, but there's a gap in genetic research due to limited genomic resources.
- This study presents a new, comprehensive genome assembly for P. californica, showcasing a large genome size of 2.40 gigabases and highlighting significant multi-species genomic variations and trends that could aid in understanding the species' genetics and conservation.
Repetitive elements (REs) are integral to the composition, structure, and function of eukaryotic genomes, yet remain understudied in most taxonomic groups. We investigated REs across 601 insect species and report wide variation in RE dynamics across groups. Analysis of associations between REs and protein-coding genes revealed dynamic evolution at the interface between REs and coding regions across insects, including notably elevated RE-gene associations in lineages with abundant long interspersed nuclear elements (LINEs).

- Djulis is an ancient crop from Taiwan, related to quinoa, known for its high nutritional value with complete proteins and essential vitamins.
- Recent genomic research produced a high-quality genome assembly for djulis, revealing 75,056 potential genes and significant repetitive sequences, particularly in its B sub-genome.
- The study also highlighted strong genetic similarities to quinoa, establishing important connections for understanding its genetics and potential conservation efforts amid changing diets and habitat loss among indigenous peoples.
Long-read sequencing is driving a new reality for genome science in which highly contiguous assemblies can be produced efficiently with modest resources. Genome assemblies from long-read sequences are particularly exciting for understanding the evolution of complex genomic regions that are often difficult to assemble. In this study, we utilized long-read sequencing data to generate a high-quality genome assembly for an Antarctic eelpout, Ophthalmolycus amberensis, the first for the globally distributed family Zoarcidae.
