AI Article Synopsis
- The bay scallop (Argopecten irradians) is important commercially, culturally, and ecologically, primarily found on the eastern U.S. coast but also farmed in China.
- Researchers assembled a detailed chromosome-level reference genome for the bay scallop, with a total size of 845.9 Mb across 1,503 scaffolds and confirmed 16 chromosomes.
- The genome includes a significant amount of repetitive elements (36.2%), is highly complete (96.2% according to BUSCO analysis), and contains 33,772 protein-coding genes, providing a resource for future evolutionary and conservation studies.
Article Abstract
The bay scallop, Argopecten irradians, is a species of major commercial, cultural, and ecological importance. It is endemic to the eastern coast of the United States, but has also been introduced to China, where it supports a significant aquaculture industry. Here, we provide an annotated chromosome-level reference genome assembly for the bay scallop, assembled using PacBio and Hi-C data. The total genome size is 845.9 Mb, distributed over 1,503 scaffolds with a scaffold N50 of 44.3 Mb. The majority (92.9%) of the assembled genome is contained within the 16 largest scaffolds, corresponding to the 16 chromosomes confirmed by Hi-C analysis. The assembly also includes the complete mitochondrial genome. Approximately 36.2% of the genome consists of repetitive elements. The BUSCO analysis showed a completeness of 96.2%. We identified 33,772 protein-coding genes. This genome assembly will be a valuable resource for future research on evolutionary dynamics, adaptive mechanisms, and will support genome-assisted breeding, contributing to the conservation and management of this iconic species in the face of environmental and pathogenic challenges.

Background: Fervidobacterium is a genus of thermophilic anaerobic Gram-negative rod-shaped bacteria belonging to the phylum Thermotogota. They can grow through fermentation on a wide range of sugars and protein-rich substrates. Some can also break down feather keratin, which has significant biotechnological potential.

The ratmouth barbel (Ptychidio jordani) is a critically endangered freshwater fish from the Cyprinidae family, primarily due to overfishing and habitat disruption. To address the challenges of its shrinking wild populations and the difficulties in artificial reproduction, we sequenced, assembled, and annotated a high-quality chromosome-level genome of P. jordani using next-generation short-read sequencing, third-generation long-read sequencing, and Hi-C sequencing.

In recent years, third-generation sequencing (TGS) technologies have transformed genomics and transcriptomics research, providing novel opportunities for significant discoveries. The long-read sequencing platforms, with their unique advantages over next-generation sequencing (NGS), including a definitive protocol, reduced operational time, and real-time sequencing, possess the potential to transform plant genomics. TGS optimizes and enhances the efficiency of data analysis by removing the necessity for time-consuming assembly tools.

Adeno-associated virus (AAV) has emerged as a powerful and effective tool for the delivery of exogenous genes into various cells or tissues. To improve the gene delivery efficiency, as well as the safety and specificity of AAV's cell-targeting capabilities, extensive investigations have been conducted into its molecular biological characteristics, including capsid structure, cellular tropism, and the mechanisms underlying its entry, replication, DNA packaging, and capsid assembly. Significant differences exist between human and non-human primate AAVs regarding tissue targeting and transduction efficiency.
