Opiots, like morphine are some of the most powerful and effective pain-killing drugs that are available.

They're made using cultivated opium poppies, which have evolved naturally to produce these chemicals probably as a way to fend off attacks

from insects.

But despite decades of study, scientists hadn't been able to unpick the biochemical production

line controlled by cellular catalysts called enzymes that lead to biochemical production

of these morphin-like chemicals.

One key part of the process remained obscure.

But now, by studying poppy plants carrying genetic changes that prevented

them from making morphine, York University's Ian Graham and his colleagues have

found the missing piece of the puzzle. We've been studying opium poppies for a number of years in

partnership with the pharmaceutical company, LaxoSmithline. In fact, not a lot of
