Genome size is a plant character with far-reaching implications, ranging from impacts on the financial and computing feasibility of sequencing and assembling genomes all the way to influencing the very ecology and evolution of species. The increasing recognition of the role of genome size in plant science has led to a rising demand for comprehensive and easily accessible sources of genome size data. The Plant DNA C-values database has established itself as a trusted and widely used central hub for users needing to access available plant genome size data, complemented with related cytogenetic (ploidy level) and karyological (chromosome number) information where available. Since its inception in 2001, the database has undergone six major updates to incorporate newly available genome size information, leading to the most recent release (Release 7.1), which comprises data for 12,273 species across all the major land plant and some algal lineages. Here we describe how to use the database efficiently, making use of its different query and filtering settings.
基因组大小是一个具有深远意义的植物特征，从影响测序和组装基因组的财务和计算可行性，一直到影响物种的生态和进化，都有着广泛的影响。越来越多的人认识到基因组大小在植物科学中的作用，导致人们对全面、易于获取的基因组大小数据的需求不断增加。植物 DNA C 值数据库已成为用户获取可用植物基因组大小数据的可信且广泛使用的中心枢纽，其中还包含了可用的相关细胞遗传学（倍性水平）和核型学（染色体数量）信息。自 2001 年成立以来，该数据库已经进行了六次重大更新，以纳入新的基因组大小信息，最终形成了最新版本（版本 7.1），其中包含了来自所有主要陆地植物和一些藻类谱系的 12,273 个物种的数据。在这里，我们将描述如何有效地使用该数据库，利用其不同的查询和过滤设置。
