An extinct variety of rye was recovered from a shipwreck at the bottom of Lake Huron

Michigan-Based Team To Resuscitate Shipwrecked Rye Seeds

In 1878, a wooden schooner named the James R. Bentley set sail from
Chicago to Buffalo, New York. But strong winds and rough waters
damaged the ship, and it sank to the bottom of Lake Huron. The crew
was saved, but the ship's cargo--a large shipment of rye--sank with
it. In the years since the shipwreck, that particular variety of rye
has faded out of existence.

Now, almost 150 years later, a Michigan-based team is trying to bring
the long-lost rye back to life. They dove to the shipwreck, retrieved
a tube full of seeds, and are planning to use gene technology to
recreate the rye variety. Their goal is to encourage farmers to grow
it, so that distillers can use it to make whiskey.
