The evolutionary origins of specialized organs pose significant challenges for empirical studies, as most such organs evolved millions of years ago. The Northern snakehead (Channa argus), an air-breathing fish, possesses a suprabranchial organ, a common feature of the Anabantoidei, offering a unique opportunity to investigate the function and evolutionary origins of specialized organs. In this study, a high-quality chromosome-level reference genome of C. argus was constructed using PacBio HiFi sequencing and Hi-C technology. The final genome assembly size is 712.14 Mb, with a scaffold N50 of 28.08 Mb. The assembled sequences were anchored to 24 pseudo-chromosomes and predicted 21,643 protein-coding genes. The genome comprises 27.70% repetitive elements and includes 3,588 (98.6%) complete BUSCOs, demonstrating superior contiguity and functional completeness compared to other published C. argus assemblies. This genome provides valuable genetic resources for exploring the evolution of the aquatic-aerial bimodal breathing system, including clarifying the evolutionary histories and adaptive strategies.

As molecular research on hemp (Cannabis sativa L.) continues to advance, there is a growing need for the accumulation of more diverse genome data and more accurate genome assemblies. In this study, we report the three-way assembly data of a cannabidiol (CBD)-rich cannabis variety, 'Pink Pepper' cultivar using sequencing technology: PacBio Single Molecule Real-Time (SMRT) technology, Illumina sequencing technology, and Oxford Nanopore Technology (ONT).

A significant portion of human cancers utilize a recombination-based pathway, alternative lengthening of telomeres (ALT), to extend telomeres. To gain further insights into this pathway, we developed a high-throughput imaging-based screen named TAILS (telomeric ALT in situ localization screen) to identify genes that either promote or inhibit ALT activity. Screening over 1,000 genes implicated in DNA transactions, TAILS reveals both well-established and putative ALT modulators.
