01Narrative

Taraxacum californicum, also known as the California dandelion, is an endangered species of dandelion endemic to the San Bernardino Mountains of California. It grows in mountain meadows.California Native Plant Society Rare Plant Profile Taraxacum californicum is a small perennial wildflower which resembles its close relative, the widespread weed known as the common dandelion (T. officinale). T. californicum has green, red-veined, lobed or toothed leaves and yellow flower heads yielding brown and white fruits. There are fewer than 20 occurrences known of the plant, and several occurrences include just a few individuals.The Nature Conservancy The plant can hybridize with the common dandelion, causing genetic pollution.

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 Taraxacum californicum has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Taraxacum californicum 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.
