主要工作：Here, we present Sex‐chrom: a database on plant sex chromosomes (www.sexchrom.csic.es), which aims to provide an easily accessible and organized information source for scientists and a general audience interested in this field.

基础模块：Basic data such as complete taxonomic classification of the species, chromosome number, genome size (2C), ploidy level, sex determination mechanism, presence of homomorphic or heteromorphic sex chromosomes and their corresponding sources are readily available for 178 species of 84 genera and 65 families.

升级模块：Besides, the database contains specific sections for 10 selected model systems in plant sex chromosome research such as Silene latifolia and Rumex acetosa. In these sections, more detailed information also is available, including data on sex‐linked genes, transposable elements or tandemly repeated DNA present in sex chromosomes.

数据来源：Data have been extracted from 431 sources published between 1919 and 2020.
