01Narrative

Isocoma rusbyi, the Rusby's goldenbush, is a North American species of plants in the family Asteraceae. It has been found in the States of Arizona, Utah, New Mexico, and Colorado in the southwestern United States. Some of the populations lie inside Grand Canyon and Petrified Forest National Parks, others in the Glen Canyon National Recreation Area.Nesom, G.L. 1991. Taxonomy of Isocoma (Compositae: Astereae). Phytologia 70(2): 69–114 description of I. rusbyi on pages 106-107, distribution map on page 75Biota of North America Program 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapter Isocoma rusbyi is a shrub up to 90 cm (3 feet) tall. Each flower head contains about 19-25 disc flowers but no ray flowers.Flora of North America, Isocoma rusbyi Greene, 1906. Rusby’s jimmyweed

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 rusbyi has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Isocoma rusbyi 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.
