01Narrative
Crotalaria rotundifolia is a flowering plant in the genus Crotalaria. It is a perennial dicot with yellow flowers that grows in the Southeastern United States. It is part of the pea family (Fabaceae). The flower arrangement is raceme and the leaf type is simple. They die back in freezing temperatures. Common names for the species include rabbitbells.

Compounds documented for Crotalaria rotundifolia across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Crotalaria rotundifolia has left across the world's sequence archives.

The complete instruction manualCrotalaria rotundifolia 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.
