01Narrative

Elymus pungens, the sea couch grass, is a species of grass of the genus Elymus in the family Poaceae. It is a common grass species native to Europe and Asia. Elymus pungens is typically found in sandy, and saline environments and can tolerate harsh weather conditions; because of this it is a common pioneer species typically associated with sand dunes.

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 Elymus pungens has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Elymus pungens 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.
