Researchers at Simon Gilroy's lab in the Department of Botany at the University of Wisconsin-Madison this afternoon greeted a truck carrying small containers holding more than 1,000 frozen plants that germinated and grew aboard the International Space Station.
On Tuesday, when Gilroy's team inspected the plants at the Kennedy Space Center in Florida, they saw exactly what they wanted: Petri dishes holding seedlings that sprouted and grew in weightlessness.
After their arrival in Madison, the plants went directly into a deep freeze. After being thawed in a few months, they will donate their RNA to an instrument that will measure the activity of all of their approximately 30,000 genes.
