Transgenic Plants

8.3K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Plant Breeding and Biotechnology

21.2K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Key Elements for Plant Nutrition

23.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Area of Science:

  • Agricultural biotechnology
  • Nutritional science
  • Plant genetics

Background:

  • Malnutrition is a major global health issue.
  • Widely consumed crops often lack essential nutrients.
  • Biofortification enhances the nutritional value of food crops.

Purpose of the Study:

  • To summarize efforts in biofortifying crops with essential nutrients like iron and folate.
  • To examine the potential of biofortified foods to influence gut microbiota.
  • To highlight the need for bioavailability studies in biofortified crops.

Main Methods:

  • Utilizing advances in molecular biology for crop biofortification.
  • Exploring genetic modification to increase nutrient concentrations (e.g., beta-carotene, iron, folate).
  • Investigating the impact of modified foods on gut microbiota.

Main Results:

  • Genetic modification offers a rapid approach to enhance crop nutritional quality.
  • Golden Rice serves as a prominent example of genetically biofortified crops.
  • Research is ongoing to increase iron and folate levels in crops.

Conclusions:

  • Biofortification, particularly through genetic engineering, holds promise for combating malnutrition.
  • Public apprehension regarding genetically modified organisms remains a significant challenge.
  • Further research is crucial to demonstrate the bioavailability of nutrients from biofortified crops and assess their impact on gut health.
