This study presents the high-quality genome assemblies for Populus alba L. Villafranca using PacBio HiFi sequencing. The assembly spans 498.95 Mb, an N50 of 18.18 Mb and the largest contig of 52.03 Mb. BUSCO analysis revealed genome completeness (embryophyta_odb10) with 98.8% of the 1,614 BUSCO groups searched. The Transposable element and repetitive content accounted for ~31.37%. The comparison of P. alba and P. trichocarpa genomes identified 9,741 structural variants (SVs). This comprehensive analysis provides valuable resources for studying poplar genome evolution, domestication, and genetic improvement, underscoring the utility of long-read sequencing for resolving complex genomic features.

The human transcription factor occupancy landscape viewed using high-resolution in situ base-conversion strand-specific single-molecule chromatin accessibility mapping
Chromatin accessibility profiling is a key tool for mapping the location of cis-regulatory elements (cREs) in the genome and tracking chromatin state dynamics during development, in response to various external and internal stimuli, and in disease contexts. Single-molecule footprinting (SMF) methods that rely on the labeling of individual accessible DNA bases have emerged in recent years as a powe...

Gene gain and loss drive the diversification of gig immune genes in teleosts: structural and regulatory insights from Atlantic salmon
Interferon-stimulated genes (ISGs) are key players in vertebrate antiviral immunity. Among teleost ISGs, the grass carp reovirus-induced gene (gig) families 1 and 2 (gig1 and gig2, respectively) are absent in mammals but conserved in fishes and amphibians, and they have been implicated in resistance to viral infections across several aquaculture species. In particular, gig1 and gig2 genes are tran...

Allostery is a widespread cause of loss-of-function variant pathogenicity
Allosteric communication between non-contacting sites in proteins plays a fundamental role in biological regulation and drug action. While allosteric gain-of-function variants are known drivers of oncogene activation, the broader importance of allostery in genetic disease and protein evolution is less clear. Here, we integrate large-scale experimental measurements and neural network models to prov...

Transcriptomic entropy reveals tissue-specific patterns in aging and predicts cancer progression
Aging and cancer share complex molecular mechanisms, yet distinguishing between causative factors and byproducts remains challenging. Here, we investigated the role of transcriptomic entropy in aging and cancer processes by analyzing RNA-sequencing data from thousands of human and mouse samples. We found that entropy changes during aging are highly tissue-specific, with some tissues showing increa...

A single cell multi-omic analysis identifies molecular and gene-regulatory mechanisms dysregulated in the developing Down syndrome neocortex
Down syndrome is the most common genetic cause of intellectual disability, presenting with cognitive, learning, memory, and language deficits. The cellular and molecular mechanisms driving this disorder remain unclear, limited by a lack of systematic studies in the developing human brain. Here, we leveraged single-nucleus multi-omics to profile the mid-gestation neocortex in a cohort of 26 donors....

Mitochondrial Genome-Based Phylogeny of Turbellarians and Evidence for Accelerated Mitochondrial Evolution in Symbiotic Species
Background: Flatworms are a highly diverse phylum with over 26,500 predominantly parasitic species. A minor portion of this diversity comprise predominantly free-living \"turbellarians\" Phylogenetic relationships within turbellarian orders remain debated, with recent mitochondrial genome studies also questioning the monophyly of the \"Neoophora clade\" . Some unique mitochondrial gene features ha...

GLM-Prior: a nucleotide transformer model reveals prior knowledge as the driver of GRN inference performance
Gene regulatory network inference depends on high-quality prior-knowledge, yet curated priors are often incomplete or unavailable across species and cell types. We present GLM-Prior, a genomic language model fine-tuned to predict transcription factor to target gene interactions directly from nucleotide sequence. We integrate GLM-Prior with PMF-GRN, a probabilistic matrix factorization model, to cr...

Single-cell RNA sequencing in Hirschsprungs disease tissues reveals lack of neuronal differentiation in the aganglionic colon segment
The enteric nervous system (ENS) is a complex network of neurons and glial cells. Hirschsprungs disease (HSCR) is a congenital condition characterized by the absence of ganglion cells in the distal colon, leading to functional bowel obstruction. In this study, we used single-cell RNA sequencing (scRNA-seq) and whole genome sequencing (WGS) to analyze healthy and aganglionic colon segments from HSC...

Recombinase Polymerase Amplification of Forensic Short Tandem Repeat Loci
Short tandem repeats (STRs) are highly polymorphic repetitive DNA sequences extensively used in forensic science for identification of individuals. STR genotyping is usually performed by capillary electrophoresis (CE) or next-generation sequencing (NGS) in centralized laboratories. However, there is an increasing need for a low cost, portable and rapid STR genotyping method. Multiple methods for m...
