Transgenic Plants

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

Plant Breeding and Biotechnology

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.

Area of Science:

Agricultural Biotechnology
Food Science
Genetics

Background:

Genetically modified (GM) crops demonstrate rapid adoption in the agribiotech industry, offering a sustainable food supply solution.
Over two decades of commercial GM crop production (1996-2015) show increasing global farmer adoption of genetic engineering.
Stacked traits in GM crops necessitate reliable detection methods for tracing and labeling in the food/feed chain.

Purpose of the Study:

To review the current status of GM crop commercialization worldwide.
To discuss the benefits and limitations of various detection systems for GM organisms (GMOs) in food and feed.
To highlight the importance of regulatory measures for GM crop detection.

Main Methods:

Review of scientific literature on GM crop commercialization and detection technologies.
Analysis of DNA-based detection methods, including conventional and advanced techniques.
Evaluation of whole genome sequencing using next-generation sequencing (NGS) for GMO detection.

Main Results:

GM crops are increasingly adopted globally, with diverse traits and mandatory or voluntary labeling schemes in many countries.
DNA-based detection methods are established, but advanced techniques like NGS offer enhanced capabilities.
Effective regulatory measures and sensitive detection are crucial for managing GM crop controversies.

Conclusions:

The widespread adoption of GM crops requires robust detection systems to ensure food and feed safety and comply with regulations.
Next-generation sequencing (NGS) presents a powerful tool for identifying GMOs with high sensitivity and specificity.
Continued research and development in detection technologies are essential for responsible GM crop management.
