The pan-genome represents the complete genomic diversity of specific species, serving as a valuable resource for studying species evolution, crop domestication, and guiding crop breeding and improvement. While there are several single-species-specific plant pan-genome databases, the availability of multi-species pan-genome databases is limited. Additionally, variations in methods and data types used for plant pan-genome analysis across different databases hinder the comparison and integration of pan-genome information from various projects at multi-species or single-species levels.

Article Synopsis
  • Single-cell transcriptome-wide association studies (scTWAS) is a cutting-edge method that enhances gene-trait association analysis by focusing on cellular precision and addressing issues of cell-type diversity inherent in traditional TWAS.
  • The scTWAS Atlas is a new comprehensive database that compiles over 2.7 million gene-trait associations linked to various traits and cell types, featuring tools for data visualization and multi-omics regulatory network construction.
  • This user-friendly platform facilitates in-depth exploration of genetic mechanisms within specific cell types, providing valuable insights for research related to human health and biological processes.

Article Synopsis
  • Human endogenous retroviruses (HERVs) make up about 8% of the human genome and have been linked to various diseases, but there hasn't been a complete resource summarizing these associations.
  • The HervD Atlas is a new knowledgebase that compiles 60,726 HERV-disease associations from 254 publications, covering a wide range of HERVs, diseases, and related genes.
  • It features an interactive knowledge graph and a user-friendly interface, making it easier to explore HERV-disease connections and potentially aiding in the development of new diagnostic and treatment options.

Cancer cell lines are essential in cancer research, yet accurate authentication of these cell lines can be challenging, particularly for consanguineous cell lines with close genetic similarities. We introduce a new Cancer Cell Line Hunter (CCLHunter) method to tackle this challenge. This approach utilizes the information of single nucleotide polymorphisms, expression profiles, and kindred topology to authenticate 1389 human cancer cell lines accurately.

Compared with conventional comparative genomics, the recent studies in pan-genomics have provided further insights into species genomic dynamics, taxonomy and identification, pathogenicity and environmental adaptation. To better understand genome characteristics of species of interest and to fully excavate key metabolic and resistant genes and their conservations and variations, here we present ProPan (https://ngdc.cncb.

Single-cell studies have delineated cellular diversity and uncovered increasing numbers of previously uncharacterized cell types in complex tissues. Thus, synthesizing growing knowledge of cellular characteristics is critical for dissecting cellular heterogeneity, developmental processes and tumorigenesis at single-cell resolution. Here, we present Cell Taxonomy (https://ngdc.

Genotype imputation is a statistical method for estimating missing genotypes from a denser haplotype reference panel. Existing methods usually performed well on common variants, but they may not be ideal for low-frequency and rare variants. Previous studies showed that the population similarity between study and reference panels is one of the key factors influencing the imputation accuracy.
