01Narrative
Apodanthera undulata, common name melon loco, is a plant species native to the south-western United States (western Texas, New Mexico, and Arizona) and in Mexico as far south as Oaxaca.Lady Bird Johnson Wildflower Center, University of Texas at Austin, Native Plant Database Apodanthera undulata is a monoecious, foul-smelling, perennial vine with a massive taproot up to 20 cm (8 inches) in diameter. Stems are prostrate, running along the ground up to 2.4 m (8 feet), sometimes climbing with tendrils. Leaves are round to kidney-shaped, up to 15 cm (6 inches) across, decidedly wavy. Flowers are yellow, trumpet-shaped. Fruits are egg-shaped with ridges running lengthwise, up to 10 cm (4 inches) long.McVaugh, R. 2001. Cucurbitaceae. 3: 483–652. In R. McVaugh (ed.)

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 Apodanthera undulata has left across the world's sequence archives.
At a glance
06Genome at a glanceCCDB
The complete instruction manualApodanthera undulata 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. Click any value below to see the underlying records and sources.
