Golden rice: Transgenic Rice with pro-vitamin A

Updated on March 2, 2014

Biotechnology, is it useful for the common people. How?

Biotechnology means 'applications of scientific and engineering principles to biological processes to provide goods and services'. Full understanding of biological processes is possible with detailed analysis of gene structure and function. Now we reach the world of Genetic Engineering. What is it? 'It means the introduction of manipulated genetic material (DNA) into a cell in such a way as to replicate and be passed on to progeny cells'. The outcome is attractive and promising.

124 million children are suffers of Vitamin A

Vitamin A is required by all individuals, deficiency of vitamin A causes night blindness. Throughout the world 124 million children are suffers of Vitamin A.

You know that rice is used as staple food almost in every country. Rice provides as much as 80 percent or more of the daily caloric intake of 3 billion people, which is half the world’s population.

Golden rice: This Rice could Save a million KIDS a year

Prof. Ingo Potrykus and Peter Beyer produced genetically enginneered rice by introducing three genes associated with the biosynthesis of carotenoid.The transgenic rice was rich in pro-vitamin A. Grains of transgenic rice is yellow in color due to pro-vitamin A, the rice is commonly known as" golden rice".

How ?

Vitamin A is synthesized from carotenoid.

The addition of 2 genes in the rice genome will complete the biosynthetic pathway

1. Phytoene synthase (psy) – derived from daffodils

2. Lycopene cyclase (crt1) – from soil bacteria Erwiniauredovora produces enzymes and catalysts for the biosynthesis of carotenoids (β-carotene) in the endosperm.

      Great hub (voted up).

      BTW: I am one of the few hubbers, that are not afraid of GM food.

      When it enters your body, it is broken to basic compounds before entering the blood stream.

      Probably nothing bad will happen if you eat slightly modified food. And if this food helps the starving or Vitamin deficient kid - all the better.

      Thank you very much for your interest.

      I totally agree with you, in third world countries vitamin A deficiency is severe problem.

      This is interesting hub... Some rice types are just empty with nutrients which are supposedly there. Such poor quality of rice are delivered to below-poverty-line communities in various parts of the world. I hope one of these days, biotechnology would mean fair provision of nutritious rice to all.
