April 25 is DNA Day.
National DNA Day commemorates the successful completion of the Human Genome Project
in 2003 and the discovery of DNA's double helix by James Watson and Francis Crick in 1953.
This annual celebration offers students, teachers and the public many exciting opportunities
to learn about the latest advances in genomic research and explore what they may mean for their
lives.

LifeScience Moment: Frostban sprayed on strawberry plants - first release of genetically altered bacteria in U.S.
On April 24, 1987, Advanced Genetic Sciences (AGS) sprayed Frostban on an acre of
strawberry plants in Brentwood, CA, marking the first release of genetically altered bacteria
in the U.S.
Stephen Lindow at the University of Wisconsin–Madison identifed the bacterium as
P. syringae, and in 1977, discovered the mutant ice-minus strain. In 1983, AGS applied
to the U.S. regulatory authorities to perform field tests with the ice-minus strain of
P. syringae, but were delayed by environmental concerns. In the end, frostban was
never marketed.
