ChromoDB is a curated database of chromosome counts for vascular plants compiled from published scientific literature. The dataset provides taxon names, accepted names when available, chromosome numbers expressed as n and/or 2n, geographic origin of the studied material when reported, bibliographic sources, and links to the corresponding ChromoDB records. This first GBIF release includes a selected subset of non-problematic records that have undergone taxonomic and bibliographic review. Additional information, updates, and extended contextual data are maintained in the ChromoDB web portal.

The dataset has global geographic scope. Geographic information refers to the reported origin of the material studied in the original chromosome-count publications, when available. Records with unclear or problematic geographic origin are excluded from this first GBIF release.

This dataset covers vascular plants. The first GBIF release includes chromosome-count records for selected taxa whose names and bibliographic sources have been reviewed in ChromoDB.

The purpose of ChromoDB is to make curated chromosome-count data for vascular plants more accessible, reusable, and citable. This GBIF publication provides a standardized subset of validated records, while the ChromoDB web portal remains the main source for extended information and more frequent updates.
Chromosome numbers are fundamental data for plant cytogenetics, taxonomy, systematics, evolution, biodiversity research, and conservation biology. ChromoDB compiles chromosome counts from published scientific literature and links them to taxonomic, geographic, and bibliographic information. This first GBIF release focuses on records considered suitable for publication after taxonomic and bibliographic review.
Each record corresponds to a chromosome-count report extracted from the scientific literature and associated with a plant taxon, the reported geographic origin of the studied material when available, chromosome numbers expressed as n and/or 2n, and the bibliographic source. Users requiring additional context, later corrections, or extended fields should consult the corresponding record in the ChromoDB web portal.
The development and curation of ChromoDB has been carried out by the research team at the Universitat de Barcelona, with the support and guidance of GBIF Spain for the publication of this dataset through GBIF.
The dataset will be updated progressively as additional ChromoDB records are curated, taxonomically checked, and bibliographically validated. The ChromoDB web portal may contain more frequent updates than the GBIF version.

1. Chromosome-count records were extracted from published scientific literature.
2. Taxon names were reviewed and linked to accepted names when possible.
3. Chromosome numbers were recorded as n and/or 2n according to the original source.
4. Geographic origin of the studied material was recorded when explicitly reported.
5. Bibliographic references were checked and standardized when possible.
6. Records considered problematic or insufficiently documented were excluded from this first GBIF release.
The study area is global and taxonomic in scope, covering chromosome-count data for vascular plants reported in published scientific literature.
Data were not generated through direct field sampling. Records were compiled from published chromosome-count studies and bibliographic sources. Each record corresponds to a chromosome-count report associated with a taxon, a reported geographic origin when available, and a bibliographic reference.
Records included in this first GBIF release were selected after taxonomic and bibliographic review. Problematic records, unresolved names, unclear bibliographic sources, doubtful chromosome numbers, and records with insufficient information were excluded from this initial publication.

ChromoDB is an ongoing project aimed at compiling, curating, and publishing chromosome-count data for vascular plants from scientific literature.
The project focuses on chromosome-count data for vascular plants at global scale, based on published scientific literature.
The dataset is based on bibliographic extraction, taxonomic review, data cleaning, and progressive validation of chromosome-count records. This first GBIF release includes only selected non-problematic records.
