Summary
This study presents new genome size (DNA C-value) data for 411 angiosperm species, including 308 novel entries. This significant contribution makes valuable biodiversity data accessible for comparative analyses.
Area of Science:
- Plant biology
- Biodiversity research
- Genomics
Background:
- Genome size (DNA C-value) is a crucial biodiversity character.
- Previous efforts compiled scattered genome size data, but many estimates remained unpublished.
- Unpublished data hinders comparative analyses and biodiversity understanding.
Purpose of the Study:
- To make a large body of valuable, unpublished genome size data accessible to the scientific community.
- To combine databasing expertise with new C-value estimates.
- To encourage the publication of further genome size data.
Main Methods:
- Flow cytometry using propidium iodide was employed to estimate C-values.
- Angiosperm species were selected primarily for horticultural interest.
- Data were compiled into a table format similar to previous publications.
Main Results:
- C-values for 411 taxa are presented, with 308 species not previously listed by Bennett and colleagues.
- The dataset represents 1.5 years of average global published output.
- This work constitutes over 12% of the latest 5-year global target for angiosperm DNA C-value data.
Conclusions:
- The study successfully makes a substantial volume of previously unavailable genome size data accessible.
- This contribution significantly advances the availability of C-value data for biodiversity research.
- The authors hope this work will inspire others to publish their unpublished data.
