Botanists Use Radiation to Design New Foods for Developing Countries

The results of random launches show how instantaneous transformations create a diversity that determines the path of selective evolution and reproduction.


The use of radiation to change genetic material within crops, a process that produces these genetic transformations, such as red grapefruit or the disease-resistant cocoa or the unusual barley Special Scotch Whiskey.


"I'm doing the same," said Lagoda, playing the four dice. I do not do anything different from what nature does. I use anything that does not exist in the genetic material itself. "


Dr. Lagouda runs a genetics and reproduction facility at the International Atomic Energy Agency (IAEA). It is very difficult to take into account the public's concerns about radiation and the risks of food manipulated by their genetic material.His work combines the two fields, but nevertheless, it has achieved prosperity.


The process leaves no radioactive waste or signs of human intervention, they simply create a new generation of crops with new characteristics.


Although little is known about the genetic improvement of improved varieties through the use of radiation, there are thousands of products transformed by radiation all over the world. mutants are several types of rice, wheat, barley, pears, cotton, mint, sunflower, peanut, grapefruit, sesame, banana, cassava and sorghum. Rradiado is used for baking and for making pasta, and converted barley is used in the manufacture of beer and whiskey of good quality.


"Automatic transformations are the engine of evolution, we imitate nature in this field, we focus on time and space for the generator to do its job during its life." We are focusing on how mutants appear, with the potential to reach 10,000 to 1 million to choose the right thing. "


The breeding of new food groups is being used in developing countries thanks to the efforts of the International Atomic Energy Agency (IAEA), Bangladesh, Brazil, China, Costa Rica, Egypt, Ghana, India, Indonesia, Japan, Kenya, Nigeria, Pakistan, Peru, Sri Lanka, Sudan, Thailand and Vietnam.


Plant scientists say that the use of radiation may play a role Important in the future: By increasing the flexibility of the grain, billions of mouths can be fed despite the decrease in land and water, high oil and chemical fertilizer costs, greater soil depletion, greater resistance of insects to deadly chemical products and climate change. Worldwide, food prices are rising rapidly.


J. Neil Rutger, director of the Pompers Center of the National Rice Research Center in Stuttgart, Arkansas, said: "This will not solve the global food crisis, but it will help – modern plant breeders use every means they can."


This method was discovered nearly 80 years ago when Louis Stadler of the University of Missouri used X-rays to expose barley seeds to radiation. The emerging seedlings were white, yellow and pale yellow, some of which had white lines, and nothing of practical value.


but the possibility was obvious. By planting large amounts of seeds and young plants, the scientists produced more transformations and found some hidden positive transformations. The peanut crust has become more solid. Barley, oats and wheat have become more productive. The black raisins are more developed.


The process was activated because the radiation randomly mixed the genetic material of the plants. The scientists were able to control the intensity of the radiation and, therefore, the extent of the damage but not the result. To know the following results they had to cultivate the material exposed to the radiation and let it grow and then study the results. The gene that crawls often kills seeds and plants or leaves them in the midst of strange transformations. But in some cases, the process has achieved benefits.


In the 1950s and 1960s, the United States promoted this method as part of its "atoms for peace" program and achieved notable successes. In 1960, the disease largely destroyed beans in Michigan, with the exception of a promising new breed that originated through breeding induced by radiation. And soon he replaced the old beans.


In the early 1970s, Dr. Rutger, in Davis, California, released gamma rays on rice. He and his colleagues found dwarf-like mutants that gave much higher yields, in part because they produced more grains.


Dr. Rutger said that currently almost half of the rice produced in California is derived from this short type. The retired scientist in the Woodland area of ​​California said he lived a few miles from where the new species grow. Dr. Lagoda said there was a jar that threatened Japanese pears, but there was resistance on a tree branch that was not exposed to radiation. He pointed out that the Japanese had cloned it and started producing a new crop and paid the prize for 30 years.


The IAEA in Vienna has helped scientists fight a virus that kills cocoa trees in Ghana, whose cocoa production accounts for 15 percent of the world's chocolate. This virus has caused the elimination of millions of cacao trees.


In Accra, the capital of Ghana, scientists at the Ghana Atomic Energy Commission (IAEA) showed the gamma shoots of gamma rays. The variables resulting from this process included a plant with better resistance to the virus. This resistant plant was planted later in 25 farms in Ghana, and there was no further growth of the virus. The IAEA has achieved similar success in the Andes of Peru, where three million people live off agriculture. The area is characterized by bad weather, but nine new varieties of barley have helped improve the blockade to the extent that farmers have surplus crops for sale.


In 2006, Professor Gómez Pando received an award in Peru for her efforts and work in products derived from the change of radiation.


In Vietnam, the agency worked closely with local scientists to improve rice production, which is food for approximately 70 percent of the population. "These new types of products have had clear economic and social effects and have helped eliminate the poverty spectrum in some provinces," the scientists said. "
