The plasmid database


PLSDB


This resource is database of plasmids by NCBI.
Plasmids can be explored and filtered using the browsing tables.
Nucleotide sequences can be searched in the database by either using Mash for longer sequences (e.g. contigs or long reads), or by using BLASTn for shorter sequences, e.g. genes.

What is new in v. 2024_05_31_v2?
  • 12,465 new records
  • Enhanced data retrieval. Incorporation of Archaea kingdom and unification of Biosample attributes. Example.
  • Identical Plasmids. Preservation of biologically relevant contextual information during the removal of duplicates. Example.
  • Improved Disease and Ecosystem Classification. Expanded classifications now include environmental ecosystems (e.g., aquatic, terrestrial) and enriched information on host-associated ecosystems (e.g., Homo sapiens, gastrointestinal system, fecal). Example.
  • Plasmid Features Annotation. Comprehensive annotation of functional structures, including protein-coding genes, MOB typing, antimicrobial resistance genes, and biosynthetic gene clusters. Example.
  • Webserver redesign. To accommodate these improvements, the webserver of PLSDB has also been reconstructed, resulting in decreased response times and enhanced visualization of features while ensuring that users have access to a more efficient and user-friendly interface.

What is new in v. 2023_11_23_v2?
  • 25382 new records
  • Removal of redundancy: elimination of Identical feature
  • New features: Assembly coverage, Taxonomy up to strain level
  • Table header names: Find the name conversions here.
