Euterpe oleracea est une espèce de palmiers de la famille des Arecaceae, originaire du Nord de l'Amérique du Sud. Il est appelé wassaï ou pinot en Guyane et ailleurs en France, mais c'est le vocable brésilien açaï qui tend à s’imposer sur les deux autres termes ailleurs en France sauf en Guyane. Il pousse en touffe serrée de plusieurs tiges. Le stipe (faux-tronc) principal peut faire au plus de 20 m de hauteur et 18 cm de diamètre. Sa couronne comporte de 8 à 14 feuilles pennées. Les fruits, nommés açais, sont des drupes violet très foncé, comestibles, et très réputées pour leur niveau élevé en antioxydants. L’açai est considéré comme l’une des espèces les plus naturellement abondantes dans les plaines inondables de l’estuaire de l’Amazone. La pulpe broyée du fruit, additionnée d’eau, donne une boisson onctueuse appelée jus de wassey en Guyane, et vinho de açaí au Brésil, bien qu’elle ne soit pas fermentée. La pulpe d'açai se dégrade rapidement et doit donc être consommée dans les 2 à 3 jours après la cueillette du fruit, ou être lyophilisée en usine. L’açai est maintenant planté pour la production de cœur de palmier. Il est cultivé comme ornemental en raison de l'élégance de ses palmes.

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 Euterpe oleracea has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Euterpe oleracea 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.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
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.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.
Record type7 871 records
Origin
Range
Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.
Museum / Voucheredphysical evidence
Backed by a physical specimen — a herbarium sheet, sample or voucher held in a collection. “Vouchered” means supported by material evidence, not just an observation.
Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Euterpe oleracea 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.
Signal

How strong is each trace?
Modelled climatemodelled
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.
