Tropidocarpum gracile is a species of flowering plant in the family Brassicaceae known by the common name dobie pod. It is native to California and Baja California, where it can be found in many types of habitat from coastal canyons to inland mountains and deserts in chaparral, scrub, woodlands, beaches, valleys, and washes. It is an annual herb producing a decumbent to erect, spreading, branching stem 10 to 50 centimeters in length. It is coated in short and long rough hairs. The basal leaves are up to 10 to 15 centimeters long and are divided into elongated lobes along the edges; leaves higher on the stem are shorter and sometimes less divided. The inflorescence is an open raceme of mustardlike flowers with four petals each about 4 millimeters long. The petals are yellow and sometimes purple-tinged. The fruit is a narrow silique several centimeters in length containing tiny brown seeds.

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 Tropidocarpum gracile has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualTropidocarpum gracile 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.

Where the DNA of Tropidocarpum gracile was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
