Transgenic golden rice

The production of fi-carotene-rich crops is an important agricultural topic. The availability of carotenoid biosynthetic genes, as well as new molecular techniques, has opened the doors for metabolic engineering. This has resulted in transgenic plants with improved nutritional quality the development of golden rice [41]. The levels of fi-carotene in the endosperm (1 to 2 p,g fi-carotene/g FW rice endosperm) although higher than wild-type rice, as this is a tissue that normally does not... 

Transgenic plants that possess nutritionally enhanced traits are also currently under development. The most recent example of this is found in the case of golden rice, an enriched rice that derives its name from its golden... 

Fig. 8.6 Bi ochemical properties and biological activity of rhLF. (A) rhLF in Coomassie blue-stained gel. Lanes 1 and 2 represent non-transgenics of Golden Promise (barley) and TP309 (rice), respectively lanes 3 and 4 show rhLF from the endosperm extracts of transgenic barley and rice, respectively lanes 5-7 indicate native human LF standard, titrated to 6, 8 and 10 pg per lane, respectively. M indicates molecular mass marker.
