Sonchus brachyotus is an Asian species of plant in the tribe Cichorieae within the family Asteraceae. It is widespread across much of northern Asia, found in Japan, Korea, China, Russia, Mongolia, Thailand, Kazakhstan, Caucasus, Kyrgyzstan, etc.Prof. Summer's Web Garden, Japanese Wild Flowers, Sonchus brachyotus includes photos Sonchus brachyotus is a perennial herb up to 100 cm tall. It produces flat-topped arrays of several flower heads, each head with 170-300 yellow ray flowers but no disc flowers. It grows on grassy slopes on mountains and alongside rivers.

Compounds documented for Sonchus brachyotus 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 Sonchus brachyotus has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualSonchus brachyotus 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.

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.
