OK—this GM crop really will glow in the dark

A group of USDA-ARS and university researchers has developed tissue markers for transgenic corn lines using green fluorescent protein, making it easier to sort through the various kernel tissues: the plant embryo, the endosperm surrounding the embryo, and the hard outer pericarp. The light-emitting gene comes from a jellyfish, and has been spliced into corn lines to glow in the embryo or endosperm portions of the kernels. Full story: Agricultural Research Service
