Triplophysa bombifrons, a species of bony fish localized in China, has largely been understudied genetically, with limited data available beyond its mitochondrial genome. This study introduces a chromosome-level genome assembly for T. bombifrons, achieved through the integration of PacBio long-read sequencing and Hi-C chromatin interaction mapping. The assembly reveals a genome structure comprising 25 chromosomes and an overall size of 655.95 Mb. The quality of this assembly is demonstrated by a scaffold N50 length of 24.25 Mb, and a genome completeness evaluation via BUSCO, which shows that 97.4% of the Vertebrata Benchmarking Universal Single-Copy Orthologs are present. Gene prediction methods including de novo, homology-based, and transcript-based, identified 34,211 genes, with 34,151 being functionally annotated. These findings may provide valuable resources in conservation, functional genomics, and molecular breeding of T. bombifrons, as well as the molecular phylogenetics and evolutionary patterns in Triplophysa.

Eriocraniidae (Lepidoptera) are widespread leaf miners and have unique adaptability to hypoxia and low temperatures, causing covert but devastating harm to Fagales (Betulaceae and Fagaceae) plants in the Holarctic. However, the lack of a high-quality genome of this most ancient family within the angiosperm-feeding group largely limits the studies on the phylogeny and environmental adaptation of the primitive Lepidoptera. In this study, utilizing Illumina sequencing, PacBio HiFi sequencing, and Hi-C technology, we constructed a chromosome-level genome assembly of E.

Wild relatives of wheat are valuable sources for enhancing the genetic diversity of common wheat. Aegilops comosa, an annual diploid species with an MM genome constitution, possesses numerous agronomically valuable traits that can be exploited for wheat improvement. In this study, we report a chromosome-level genome assembly of Ae.

The barbel chub Squaliobarbus curriculus, is an economically important freshwater fish in China. The fishery production of the wild populations has declined dramatically, making the development of aquaculture urgently needed. However, the lack of high-quality genome has impeded its artificial breeding and genetic breeding.
