Unripe fruit and thorns Solanum linnaeanum is a nightshade species known as devil's apple and, in some places where it is introduced, apple of Sodom. The latter name is also used for other nightshades and entirely different plants elsewhere, in particular the poisonous milkweed Calotropis procera. This poisonous plant bearing tomato-like fruit is native to many African countries Kenya, Tanzania, South Africa,AWC (2004) Zimbabwe and Mozambique,Species Fact Sheet, Queensland Government and is considered to be an invasive species in Australia,DAF-WA [2006] New Zealand,Roy et al. (2005) Hawaii, Fiji, New Caledonia, other Pacific Islands, the Aseer region of Saudi Arabia, and northern areas of Pakistan.Information on Solanum linnaeanum as relevant to Pacific Islands also in Aseer region in Saudi Arabi and northern areas of Pakistan When raw its fruits are green and look exactly like the Thai eggplant and when ripe they are yellow. In Ukambani eastern Kenya children in the villages in summer season use the poisonous yellow fruit as football, cautiously. Solbec Pharmaceuticals attempted to develop Coramsine,SP [2006] a 1:1 mixture of the alkaloids solamargine and solasonine extracted from Solanum linnaeanum, as a cancer drug. Preliminary clinical trials were initially promising,Millward et al. (2005) but the drug was ultimately unsuccessful. Solanum linnaeanum may be confused with Solanum cinereum (Narrawa burr) in Australia, the neotropical Solanum capsicoides, or Solanum incanum in Africa.

Compounds documented for Solanum linnaeanum across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Solanum linnaeanum has left across the world's sequence archives.

The complete instruction manualSolanum linnaeanum 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.
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.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

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.
