01Narrative

Ranunculus ambigens, common names water-plantain spearwort, water plantain, and spearwort, is a plant found in North America. It is listed as endangered in Connecticut,"Connecticut's Endangered, Threatened and Special Concern Species 2015". State of Connecticut Department of Energy and Environmental Protection Bureau of Natural Resources. Retrieved 17 January 2018. (Note: This list is newer than the one used by plants.usda.gov and is more up-to-date.) and New Hampshire, as endangered and extirpated in Maryland, as a special concern in Kentucky, as possibly extirpated in Maine, as threatened in Michigan, and as a special concern in Rhode Island.

05DNA & barcodingmolecular

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Ranunculus ambigens has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Ranunculus ambigens carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.

Chromosomes & ploidyhow the DNA is packaged

2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.
