Potato ring rot caused by has been a devastating disease in the U.S. since 1930. In this study, we isolated a recent strain, K496, from potato tubers showing discolorations of the vascular cylinder or pith tissues. We de novo assembled the genome sequence of K496 with 1,924,544,313 bp of Nanopore reads (N = 13,785 bp) using Flye v2.9 and polished it with 2 × 150 bp paired-end Illumina reads (855,788,703 bp in total). The resulting genome of K496 consists of a single circular chromosome 3,266,016 bp long and a linear plasmid of 135,489 bp. Using the NCBI PGAP v5.3, this genome was predicted to have 3,301 genes, encompassing 3,247 protein-coding genes, 90 pseudogenes, two 5S rRNA-coding, two 16S rRNA-coding, two 23S rRNA-coding sequences, 45 tRNAs, and three noncoding RNAs. The chromosome and plasmid sequences have been deposited at the NCBI GenBank database under the accession numbers CP088266 and CP088267, respectively.

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).

Long non-coding RNAs (lncRNAs) play crucial roles in numerous biological processes and are involved in complex human diseases through interactions with proteins. Accurate identification of lncRNA-protein interactions (LPI) can help elucidate the functional mechanisms of lncRNAs and provide scientific insights into the molecular mechanisms underlying related diseases. While many sequence-based methods have been developed to predict LPIs, efficiently extracting and effectively integrating potential feature information that reflects functional attributes from lncRNA and protein sequences remains a significant challenge.

Objectives: Associations of ABO blood group specifying transferases A/B (ABO) and fucosyltransferase 2 (FUT2) with CP remain inconclusive. We aimed to comprehensively investigate the associations by Chinese sequencing cohorts and external cohorts.

Methods: First, we analyzed the distributions of ABO blood groups and FUT2 status, along with lead single nucleotide polymorphisms (SNPs) at ABO (rs8176693 C/T) and FUT2 (rs632111 A/G) gene loci in Chinese low-coverage whole-genome sequencing discovery cohort.

Background: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) has become essential for diagnosing pancreatic ductal adenocarcinoma (PDAC) and is increasingly utilized for comprehensive genome profiling (CGP) to advance precision medicine. This systematic review and meta-analysis assess the feasibility and clinical utility of EUS-TA samples for CGP in PDAC.

Methods: We conducted a thorough systematic literature search in PubMed, EMBASE, and the Cochrane Library up to October 2023.

Microsatellites, or simple sequence repeats (SSRs), are short tandemly repeated DNA sequences widely dispersed throughout the genome. Their high variability, co-dominant inheritance, and ease of detection make them valuable genetic markers, frequently used to study genetic diversity, population structure, and evolutionary processes. In the context of malaria research, particularly with Plasmodium falciparum (P.
