The supernumerary mostly dispensable B chromosomes are nuclear components of about 15% of eukaryotic phyla. For a long time, B chromosomes have been studied, generating an enormous bulk of knowledge, diluted in the vastness of the scientific literature. In order to provide better access to this information, we created B-chrom ( www.bchrom.csic.es ), an online database with comprehensive information on Bs for plants, animals, and fungi. It was released in 2017 and first updated in 2021, by adding 334 entries and 123 new species. Currently, the resource provides information for 2951 species coming from 3292 sources. During this time, the usefulness of this database has been proven by the number of visits (more than 207,000 since its release) and by the scientific community, having been cited in more than 60 publications until present. This chapter explains the database composition and tips on how to use it.
额外的、大多是可有可无的 B 染色体是约 15%真核生物门的核组成部分。长期以来，B 染色体一直是研究的对象，产生了大量的知识，但这些知识在浩瀚的科学文献中被稀释了。为了更好地获取这些信息，我们创建了 B-chrom（www.bchrom.csic.es），这是一个在线数据库，包含植物、动物和真菌的 Bs 综合信息。它于 2017 年发布，并于 2021 年首次更新，增加了 334 条记录和 123 个新物种。目前，该资源为来自 3292 个来源的 2951 个物种提供信息。在此期间，该数据库的实用性已通过访问量（自发布以来超过 207000 次）和科学界得到了证明，截至目前已被引用超过 60 次。本章介绍了数据库的组成和使用方法。
