Gene Banks for a Warming Planet [PDF]

open access: yesScience, 2009
The bicentenary of Charles Darwin's life and work reminds us that the great biodiversity on Earth underlies natural selection, selective breeding, and the biotechnologies required to provide humanity with food, fiber, fodder, and fuels. In particular, biodiversity affords the development of plant varieties with novel genetic combinations, which will be
