01Narrative

Prunus brigantina, called Briançon apricot (), Briançon plum (), marmot plum (), and Alpine apricot, is a wild tree species native to France and Italy.Altervista Flora Italiana, Prunus brigantina Vill. includes photos and European distribution map Its fruit is edible and similar to the commercial apricot P. armeniaca, but it is smooth unlike apricots. An edible oil produced from the seed, 'huile des marmottes', is used in France. It is disputed whether P. brigantina is an apricot or a plum. It is grouped with plum species according to chloroplast DNA sequences, but more closely related to apricot species according to nuclear DNA sequences.

05DNA & barcoding3 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 Prunus brigantina has left across the world's sequence archives.

06Genome at a glanceCCDB · GoaT · NCBI

The complete instruction manual Prunus brigantina 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≈259 721 188 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. Click any value below to see the underlying records and sources.

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.

09Environmental DNA3 detections

Where the DNA of Prunus brigantina 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
