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.
Given that bioconversion of Î²-carotene from Golden Rice is a very efficient process, as highlighted on the homepage of this website, a typical diet containing GR2 has a great potential to help alleviate vitamin A deficiency-induced diseases. The image clearly shows the progress made since the proof-of-concept stage of Golden Rice.
