Spatial Data Objects. The geometry and geography data types support sixteen spatial data objects, or instance types. However, only eleven of these instance types are instantiable; you can create and work with these instances (or instantiate them) in a database.
Rewiring the grain. Metabolic engineering. Golden Rice technology is based on the simple principle that rice plants possess the whole machinery to synthesise Î²-carotene, and while this machinery is fully active in leaves, parts of it are turned off in the grain.
The beginnings of Golden Rice Golden Rice: The First Generation. The first breakthrough in the development of Golden Rice was the result of a collaboration between Peter Beyer and Ingo Potrykus, and was obtained around Easter 1999 (Ye et al., 2000). This paper provided the proof that Î²-carotene could be produced in the rice grain.
