Release 6.0 of the Plant DNA C-values database

Since December 2010 when release 5.0 went live, new genome size data have continued to be published at a considerable rate. This new release contains data for over 1400 species not listed in any previous compilation taken from 90 reference sources. Of these, the vast majority are for angiosperms with new values for over 1200 species. Nevertheless, there has also been a considerable increase in the amount of data for gymnosperms with first estimates reported for over 150 species, including representatives for all cycad genera. There has also been some progress made for pteridophytes with first reports of genome size data for over 40 species, including representatives of both the monilophytes and lycophytes. Sadly there have been no new reports for bryophytes comprising mosses, liverworts and hornworts, despite their key phylogenetic position representing the earliest groups of land plants.

Release 5.0 of the Plant DNA C-values database

The last major update of the Plant DNA C-values database (release 4.0) was in October 2005. Since then interest in genome sizes has remained high with first estimates for over 2200 C-values published, including over 1800 species not listed in any previous release. These data, taken from over 150 reference sources, have now been added to the database. The majority of the new data are for angiosperms but additional values for other land plant groups have been added where available.

Release 4.0 (October 2005) of the Plant DNA C-values database

Since release 3.0 of the Plant DNA C-values database in December 2004 new data for 411 angiosperm species (including 308 species not previously listed) have been published in Zonneveld et al. (2005). These data have now been added to the database. A full list of the new data together with associated footnotes is published in hard copy in Zonneveld et al. (2005). The total number of angiosperm species listed with C-values is now 4427.

Future updates planned

As new data become available we will periodically update the database. We welcome receiving published offprints, preprints, and personal communications giving DNA amount estimates for plants not already included in this database.

Please send DNA C-value data to Dr Ilia Leitch at the Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AB.
