01Narrative

Спо́рыш распростёртый — однолетнее растение, вид рода Спорыш (Polygonum) семейства Гречишные (Polygonaceae). Встречается также под устаревшим синонимичным названием Горе́ц распростёртый. Отличительной чертой вида является супротивное расположение значительной части листьев, в особенности нижних. Распространён в Евразии и на северо-западе Северной Америке, объединяет два морфологически и географически обособленных подвида.

05DNA & barcoding7 specimens

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 Polygonum humifusum has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Polygonum humifusum 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.

09Environmental DNA8 detections

Where the DNA of Polygonum humifusum 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.
