With similar modification, rice seeds can contain two to four times the usual content of iron in them. Yellow-coloured rice seeds with 'beta carotene' precursor of Vitamin A in it or crops with salt resistant genes that can be grown in coastal areas.
Transgenic plants hold out a hope to farmers if they are so modified to resist to a specific pest.
A virus resistant papaya has already been commercialised and grown in Hawaii since 1996. Use of pest-resistant transgenic plants would also lead to reduced use of pesticides, benefitting the environment. A salt tolerance gene from mangroves has been identified, cloned and transferred to other plants. These transgenic plants were found to be tolerant to higher concentrations of salt. Such crops could be used for cultivation in the coastal areas.
