John Barleycorn Must DNA

Barley made the news in 2012 when a cadre of international researchers managed to sequence the genome for barley, said to be “one of the world’s most important and genetically complex cereal crops“. Results were published in the journal Nature. Apparently this work could lead to higher barley yields, better resistance to pests, and enhanced nutritional value. It may also help barley adapt to the stresses of climate change.

You know what that means – we can trash the environment and still have beer!

Congratulations to the researchers. A round for all my genome sequencing friends! It made me think of a great old song about barley and its role in the beer and whiskey making process – John Barleycorn Must Die!

And then, after two strong beers,  I thought of how I might take that great old song and ruin it forever.

 

The scientists have done their best
employing all their means
They found out, using every test,
John Barleycorn has genes!

They chopped him up so very small
and put him on display.
Tore him apart to see it all
and mapped his DNA.

If you were him by now you’d know
the sum of all your parts.
What makes you wilt. What helps you grow.
The compounds in your farts.

The sequence tells us who he is,
of what he is composed.
His elements, his spark, his fizz.
John Barleycorn, exposed.
