Cereus jamacaru est une espèce de cactus. Il est commun dans le Nordeste, au Brésil, où il atteint couramment 5 mètres de hauteur. Une forme inerme est utilisée pour nourrir les animaux. Le type le plus courant est très épineux et est également utilisé pour l’alimentation animale, après avoir brûlé ou coupé les épines. Le Mandacaru est hautement résistant à la sécheresse. Les fleurs sont blanches et d'environ 30 centimètres de long. Les boutons floraux apparaissent généralement à la mi-printemps et chaque fleur éclot seulement pendant une nuit. Ils fleurissent au crépuscule et se fanent au matin. Son fruit a une très forte coloration violette. La pulpe est blanche avec des petites graines noires, et il est considéré comme étant très savoureux. Beaucoup d’oiseaux s'en nourrissent, tels que le « gralha-cancã » et la « periquito-da-caatinga » de la caatinga brésilienne.

05DNA & barcoding4 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 Cereus jamacaru has left across the world's sequence archives.

The complete instruction manualCereus jamacaru 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
Genome size≈1 472 447 148 bp assembly estimate
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.

Where the DNA of Cereus jamacaru 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.
