The recent work by DeLoache, et al. on a synthetic opiate-precursor production pathway in yeast has generated a lot of scare stories in the media about people homebrewing heroin as easily as they would beer.
In connection with DeLoache and coworkers' research, the New York Times has claimed
Their DNA could be put on a watch list, as sequences for anthrax and smallpox are, so any attempt to buy them from DNA supply houses would raise flags.
I have never heard of such a watch list, and a thorough googling turned up nothing relevant save for the NYT article itself. Does this watch list exist?
