Solidago ptarmicoides, the prairie goldenrod, white flat-top goldenrod or upland white aster, is a North American perennial flowering plant in the family Asteraceae. It is native to the central and eastern Canada (from New Brunswick to Manitoba) and parts of the United States (mostly Great Lakes region, the Northeast, the Ozarks, and the northern Great Plains, with isolated populations in Wyoming, Colorado, Oklahoma, and scattered locations in the Southeast. It has also been called upland white solidago, upland white goldenrod, and sneezewort goldenrod

The complete instruction manualSolidago ptarmicoides 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 size929 100 000 bp
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.

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.
