01Narrative

Isocoma hartwegii is a Mexican plant species in the family Asteraceae. It has been found in the states of Jalisco, Zacatecas, Aguascalientes, Hidalgo, Guanajuato, and San Luis Potosí. Isocoma hartwegii is a subshrub. Each flower head has 13-22 disc flowers but no ray flowers.Nesom, G.L. 1991. Taxonomy of Isocoma (Compositae: Astereae). Phytologia 70(2): 69–114 description of I. humilis on pages 91-92, distribution map on page 73

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 hartwegii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Isocoma hartwegii 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.
