Scientists mapped the pepper genome

There had better not be any 7+ million scoville peppers coming out of this though. It takes away from all the competition of trying to breed one if you can just replicate the gene a few extra times have it be stable on the first go.
 
The sequencing also uncovered evidence suggesting that the pungency, or “heat,” of the hot pepper originated through the evolution of new genes by duplication  of existing genes and changes in gene expression after the peppers evolved into species.
 
Well now they are just lying. Peppers didnt evolve.

Whoever wrote this has now clue how genetics works. Peppers didn't "evolve into species". Peppers, once they evolved, where already species. You can't have a lifeform without having a species to put it in. There was never a pepper that wasn't a species. And genes to not 'evolve by duplication' They evolve by mutations. Having more of the heat gene will increase heat. Having more of it will not change what it is into a new gene. Gene expression does not change what a gene is either. Mutation is what changes a gene.
Rant over. As a scientist, that made me cringe.
As a side note, a very interesting article.
 
Interesting article.  (Your's, too, Nigel.)
 
FTA - "The variety, known as Criolo de Morelos 334, has consistently exhibited high levels of disease resistance..."
 
Is anyone growing this variety?
 
FTA - "More than 22 of these “heat”-producing compounds have been isolated..."
 
I knew there were several, but did not know the count was up to 22.

Duplication is a form of mutation. Partial sequences or entire genes can undergo duplication.
 
Here's the actual research paper, it seems to be available for free:

Duplication can be mutation. The chromosome that houses the gene is definitely mutated. They were talking about the gene itself. When parts of a gene duplicate, the usual result is referred to as "it stop being good now" because it would run an essential step twice, leaving extra stuff behind and wasting energy. I can see where the're coming from on that. Thanks for the actual paper, gonna read through this on my spare time.\
 
Edit: also, has Ed released his research paper on cancer affecting rates of peppers? There are some experiments I need to run and I need to run them in a way that he hasn't.

It's worded horribly.
