01Narrative
Panicum urvilleanum is a species of grass known by the common names desert panicgrass and silky panicgrass. It is native to the southwestern United States and northern Mexico, where it grows in sandy habitat, including the dunes of the deserts. It is also known in parts of South America. This is a stoloniferous perennial grass growing up to a meter tall with hairy leaves up to 45 centimeters long. The inflorescence is a branching, spreading panicle up to 35 centimeters long bearing oval-shaped spikelets coated in downy white or silvery hairs.

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 Panicum urvilleanum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPanicum urvilleanum 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.
