“Secret Codes in Bacteria”

In Michael Stackpole’s book I, Jedi, set in the Star Wars universe a few years after Return of the Jedi, the main character must develop his latent Jedi abilities in order to track down and rescue his kidnapped wife. Unfortunately, the late and unlamented Emperor has done a very thorough job of wiping out all the Jedi lore he could find (as well as almost all of the Jedi and their offspring), and there’s little for Corran to go on.

His adopted grandfather, who had been a liaison with the Jedi who was Corran’s real grandfather before the Emperor rose to power, had done more than altering records and adopting Corran’s father when he saw what was happening. He’d also encoded all the Jedi lore that he could find in a place that none of the Emperor’s minions would think to look for it: the DNA of the flowers that he now breeds in his retirement.

If that wasn’t the impetus for these scientists, it should have been 🙂
