The alteration of crops to improve their production was performed through the basis of selection before the creation of transgenics. This selection has been going on for thousands of years. By the year 2050, world population may reach nine billions. Food production will need to increase at the same rate or more in order to satisfy the needs of such an enormous number of people in some older centuries. So, there is a need to use the genetic techniques to improve crops over the recent decades.Continue Reading Transgenic Plants – Botany Notes – For W.B.C.S. Examination.

Through the use of transgenics, one can produce plants with desired traits and even increased yields. The transgenics would allow for more crops that last longer and withstand pests and diseases. Transgenic plant production will allow us to feed the growing population and to produce more desirable products. The future of GM crops remains a vital debate, as its applications have several advantages and disadvantages.

Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics.They are identified as a class of genetically modified organism (GMO).

Transgenic plants are able to produce medicine of desired therapeutic value. They consist of elements of two different species. Transgenics helps scientists to develop organisms that express a novel trait not found in a species normally; for example, potatoes (protein rich) or rice that has elevated levels of vitamin A (known as “golden rice”) . These may be used to save endangered species, e.g., American Chestnut tree, currently being repopulated by Chinese–American chestnut hybrids specifically engineered with a genetic resistance to the chestnut blight (the deadly fungus that nearly decimated native populations in the early 1900s) . Transgenic have also been used to develop novel vaccines such as edible vaccines. A transgenic plant project, known as the “glowing plant project,” incorporated a gene from a firefly into a houseplant, resulting in plants displaying a soft illumination in the darkness. This was to create trees that could illuminate streets and pathways, thereby saving energy and reducing our dependence upon limited energy resources. However, this has sparked a heated debate related to potential environmental consequences via using highly GE plants into natural ecosystems.
