Pocket K No. 2: Plant Products of Biotechnology


Plant products of biotechnology have been available in the market for 23 years in 2018.  These modified crops look like their traditional counterparts, but they possess special characteristics that make them better. These crops offer several benefits both farmers and consumers.  Farmers gain higher crop yields and have increased flexibility in management practices while consumers have “healthier crops” (i.e., crops grown with fewer pesticides and/or with healthier nutritional characteristics).

Plant products of biotechnology approved for food use have been modified to contain traits such as:
•     Insect resistance
•     Disease resistance
•     Herbicide tolerance
•     Altered nutritional profile
•     Enhanced storage life

BIOTECH SOYBEAN

Soybean is the oil crop of greatest economic relevance in the world. Its beans contain proportionally more essential amino acids than meat, thus making it one of the most important food crops today. Processed soybeans are important ingredients in many food products.

 

Herbicide tolerant soybean
Herbicide tolerant soybean varieties contain a gene that provides resistance to one of two broad spectrum herbicides.

This modified soybean provides better weed control and reduces crop injury. It also improves farm efficiency by optimizing yield, using arable land more efficiently, saving time for the farmer, and increasing the flexibility of crop rotation. It also encourages adoption of no-till farming - an important part of soil conservation practice. These varieties are the same as other soybeans in nutrition, composition, and in the way they are processed into food and feed. *Approved (for import or cultivation) in the following countries: Argentina, Australia, Bolivia, Brazil, Canada, Chile, China, Colombia, Costa Rica, European Union, India, Indonesia, Iran, Japan, Malaysia, Mexico, New Zealand, Nigeria, Paraguay, Philippines, Russia, Singapore, South Africa, South Korea, Switzerland, Taiwan, Thailand, Turkey, United States of America (USA), Uruguay, and Vietnam.

Insect resistant soybean
This biotech soybean exhibits resistance to lepidopteran pests through the production of Cry1Ac protein. Insect resistant soybean was developed to reduce or replace high insecticide applications and at the same time maintain soybean yield potential.*Approved (for import or cultivation) in the following countries: Argentina, Australia, Brazil, Canada, China, Colombia, EU, India, Indonesia, Iran, Japan, Malaysia, Mexico, New Zealand, Nigeria, Paraguay, Philippines, Russia, Singapore, South Africa, South Korea, Taiwan, Thailand, Turkey  USA, Uruguay, Uruguay.

Oleic acid soybean
This modified soybean contains high levels of oleic acid, a monounsaturated fat. According to health nutritionists, monounsaturated fats are considered “good” fats compared with saturated fats found in beef, pork, cheese, and other dairy products.

Oil processed from these varieties is similar to that of peanut and olive oils. Conventional soybeans have an oleic acid content of 24%. These new varieties have an oleic acid content that exceeds 80%.*Approved (for import or cultivation) in the following countries: Argentina, Australia, Brazil, Canada,China, Columbia, EU, Indonesia, Iran, Japan, Malaysia, Mexico, New Zealand, Nigeria, Philippines, Singapore, South Africa, South Korea, Taiwan, Turkey, US, and Vietnam.

 


BIOTECH MAIZE

Maize is one of the three most important grains of the world. It is used as livestock feeds, processed as cooking oil and food additives, and currently as feedstocks for biofuels.

Herbicide-tolerant maize
These maize varieties work in a similar manner as herbicide-tolerant soybean. They allow growers better flexibility in using certain herbicides to control weeds that can damage crops.*Approved (for import or cultivation) in the following countries: Argentina, Australia, Brazil, Canada, China Colombia, Costa Rica, Cuba, EU, Honduras, Indonesia, Iran, Japan, Malaysia, Mexico, New Zealand, Nigeria, Pakistan, Panama, Paraguay, Philippines, Russia, Singapore, South Africa, South Korea, Switzerland, Taiwan, Thailand, Turkey, USA, Uruguay, Vietnam, and Zambia.

Insect resistant maize
This modified maize contains a built-in insecticidal protein from a naturally occurring soil microorganism (Bacillus thuringiensis) that gives maize plants season-long protection from corn borers. This means most farmers do not have to spray insecticide to protect maize from harmful pests, which can cause significant damage and yield loss in many areas. Bt maize also reduces toxin contamination arising from fungal attack on the damaged grain. The Bt protein has been used safely as an organic insect control agent for over 50 years. *Approved (for import or cultivation) in the following countries: Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, European Union, Honduras, Indonesia, Iran, Japan, Malaysia, Mexico, New Zealand, Nigeria, Pakistan, Panama, Paraguay, Philippines, Russia, Singapore, South Africa, South Korea, Switzerland, Taiwan, Thailand, Turkey, USA, Uruguay, Vietnam, and Zambia.

 

BIOTECH RICE

Rice is life for more than half of humanity. It is the staple food for over 3 billion people, more than 90% of whom are Asians.

Herbicide-tolerant rice
These rice varieties work in a similar manner to herbicide-tolerant soybean. They contain a gene that provides resistance to one of two broad spectrums, and environmentally benign herbicides. *Approved (for import or cultivation) in the following countries: Australia, Canada, Colombia, Honduras, Mexico, New Zealand, Philippines, Russia, South Africa, and the USA.

CONCLUSION

In developed countries , the use of GM crops has evidently resulted in significant benefits. These “first generation” crops have proven their ability to increase crop yields, reduce farm costs, increase farm profit, and help protect the environment. With the “second generation” of GM crops, the focus has been on increased nutritional, pharmaceutical, and/or industrial traits. These varieties should prove valuable in countries where millions of people suffer from dietary deficiencies and have difficulties in accessing vaccines and medicines.
