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.
