01Narrative

Eutrochium steelei, also known as Appalachian Joe-Pye weed or Steele's eupatorium, is a North American species of plants in the family Asteraceae. It is found only in the Appalachian Mountains of the eastern United States, in the States of Virginia, Kentucky, Tennessee, North Carolina, and Georgia. Eutrochium steelei is a perennial herb sometimes as much as 200 cm tall. Stems are greenish-purple, not hollow. One plant can produce many small pink or purple flower heads, each head with 5-10 disc flowers but no ray flowers.

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 Eutrochium steelei has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Eutrochium steelei 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.
