01Narrative

Isocoma coronopifolia, the common goldenbush, is a North American plant species in the family Asteraceae. It has been found on both sides of the Río Grande, in Tamaulipas, Coahuila, Nuevo León, Chihuahua, and southern Texas. Isocoma coronopifolia is a shrub up to 120 cm (4 feet) tall. The plant produces flower heads in clusters on the tips of branches, each head containing 12-15 disc flowers but no ray flowers.Nesom, G.L. 1991. Taxonomy of Isocoma (Compositae: Astereae). Phytologia 70(2): 69–114 description of I. coronopifolia on pages 86-87, distribution map on page 74

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 Isocoma coronopifolia has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Isocoma coronopifolia 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.
