A transgenic food crop, which may help in solving the problem of night blindness in developing countries is

  • Flavr savr tomatoes

  • Starlink maize

  • Bt soybean

  • Golden rice

Solution

D.

Golden rice

Vitamin -A deficiency causes night blindness among children. Vitamin - A deficiency often occurs where rice is the staple food since rice grain does not contain Beta carotene. Three transgenic providing phytoene synthase, phytoene desaturase, zeta-carotene desaturase and lycopene cyclase activities were transferred into rice by Agrobacterium mediated transformation. The resulting transgenic rice popularly called golden rice contains good quantities of Beta-carotene.
Flavr savr is genetically modified tomato, which remains fresh and retains their flavour much longer than normal tomato due to blocking of synthesis of fruit softening enzyme polygalacturonase.
