Methodological approach

Publication search strategy

A search procedure was designed to retrieve scientific documents which included plant sex chromosome data. The databases used were Scopus and WOS (Web of Science). The search strategy consisted of the name of each of the genera covered by the database and several keywords such as "sex chromosome", “karyotype”, “cytotaxonomy” or “cytogenetic*”. In the cases of some genera which had few occurrences, the name of the family was added to the search strategy in order to find possible results. During this process part of the initially recovered documents were discarded and as a result 465 articles, books and meeting proceedings were found to provide significant information of plant sexual chromosomes.

 

Data mining

The information was manually extracted from each source publication and when available (in most cases), the presence and type of sex chromosomes were visually checked in the pictures. Data was introduced in a Google Sheet and the following fields were filled for each entry: (1) clade-upper (large plant group), (2) clade-lower (monocots, eudicots and other divisions), (3) order, (4) family, (5) genus, (6) specific epithet, (7) species name, (8) infraspecific category, (9) taxonomic status, (10) accepted name, (11) accepted authorship, (12) genome size, (13) sexual system, (14) chromosome number (2n), (15) ploidy level, (16) sex determination mechanism, (17) sex chromosomes male, (18) sex chromosomes female, (19) heteromorphic or homomorphic sex chromosomes, (20) source, (21) method for the primary characterisation of sex determining system, (22) miscellaneous genomic information, (23) source (miscellaneous).

 

How to use

Sex-chrom includes 689 data entries. Each entry is ascribed to a plant species, genus, family, order or class. The easiest way to use the database is by inserting the name of a genus or a species in the search box. Certain groups for which more specific information is available (Asparagus officinalis, Cannabis sativa, Carica papaya, Fragaria, Humulus, Marchantia polymorpha, Mercurialis annua, Populus, Rumex acetosa and Silene latifolia) can be accessed by browsing in their own sections.
