Panicum virgatum, le panic érigé ou millet vivace, est une espèce de plantes monocotylédones de la famille des Poaceae (graminées), sous-famille des Panicoideae, originaire d'Amérique du Nord. Ce sont des plantes herbacées, vivaces, très répandues aux États-Unis, autrefois considérées comme des céréales sauvages. L'espèce est présente sur tout le territoire américain. Le gouvernement des États-Unis considère, depuis 2006, le panic érigé comme une source potentielle d'agrocarburants, plus respectueuse de l'environnement que d'autres, et qui pourrait réduire la dépendance des États-Unis à l'égard du pétrole. Les anglophones lui ont donné de nombreuses dénominations vernaculaires « Tall panic grass », « Wobsqua grass, « Lowland switchgrass », « Blackbent », « Tall prairiegrass », « Wild redtop », « Thatchgrass » ou tout simplement « Switchgrass ».

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 Panicum virgatum 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 Panicum virgatum 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.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Panicum virgatum 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
Where its DNA was found
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.
