Marker assisted biofortification of rice with pro-vitamin A using transgenic Golden Rice® lines: progress and prospects

Published on

Rice (Oryza sativa L.) is the major staple food crop which
feeds more than half of the world’s population. However,
rice endosperm lacks pathway to synthesize provitamin
A. Therefore, rice eaters particularly children and pregnant
women suffer due to vitamin A deficiency (VAD) which,
besides causing night blindness, also makes them more
prone to a range of ailments. With the aim of overcoming
VAD, Golden Rice® lines were developed by connecting
the missing links of β-carotene pathway in the rice
endosperm through genetic transformation. We present
an overview on the origin of Golden Rice® concept,
development of prototypes, different generations of
Golden Rice®, various events and their characteristics, the
progress in marker assisted development of Golden Rice®
and future prospects in India.
