According to Prof. Jorge Dovchovski from the University of California at Davis and Prof. Leif Andersson from the University of Uppsala in Sweden who studied the genomes of plants and domesticated animals (respectively): during ten thousand years of evolution we adapted the plants and domesticated animals to our needs
Prof. Jorge Dovchovski from the University of California, Davis and Prof. Leif Andersson from Uppsala University in Sweden won the 2014 Wolf Prize for Agriculture for their groundbreaking contribution to plant and animal science research through the use of advanced technologies in genome research. The researchers presented the research that earned them the prize at a conference held last Thursday in the Knesset. The two received the award yesterday (Sunday) from the president of the country together with the winners in the five other fields.
Anderson won the award for a breakthrough in the study of domesticated animals using tools developed for the Genome Project. "For 10,000 years we changed the animals and adapted them to environments that were foreign to them. For most of these years we lived near the animals that were our homes, but in the last generation we lost this connection."
Anderson says that hybrids made over the years have caused differences within populations of animals of the same species. An example of this is that there are many more than one breed of domestic chicken, and there are genetic differences between them. "One of my colleagues conducted such an experiment and bred chickens, where in each generation he selected them according to size and separated the largest and smallest chickens. This is how two populations were created. When we used the systems developed for the human genome project, we saw the genetic differences between the two populations."
"In my laboratory, we study all domesticated animals (cows, chickens, pigs, sheep, horses, as well as pets) and we have been able to carry out studies based on genetic mapping in almost all of them. The goals of the research are to identify the genes and the mutations that occur in them and which cause the differences that manifest themselves in the vast variety of the animals and we intend to develop new knowledge about the biological mechanisms, which will provide us with tools that can be applied in animal breeding Another is to get new information about humans, because many genes are shared or similar between humans and animals."
"Already at the beginning of the era of genome research, in 1989 I decided to try to see what was happening in the animal world and researched how the wild pig could be changed and turned into a domesticated one. We did hybridization and created a hybrid animal characterized by a mixture of genes that were different between the animals. The hybridized pigs had stronger muscles and Lower fat, thanks to a gene related to insulin activity and heart rate, we discovered the binding protein in the sequence of those genes, And we found that it also exists in humans. We actually discovered a new mechanism that regulates the heart rate in humans."
"This is perhaps the most important experiment in my scientific career where we used genetics to show why the difference is so important. After comparing the sequences we saw that the sequence of the wild boar can bind the protein ZBED6 and the domestic pig cannot. Through comparison with other animals we showed that this sequence goes into The genome 200 million years ago and for millions of years the gene disappeared in some animals. The protein is very concentrated and is found in the placenta of all mammals And so we concluded that the genome changed the body's natural selection and removed it in those animals."
"We found mice that don't have this gene and thus we actually returned to the situation of 200 million years ago, and we are investigating what happens in the absence of the gene. This is how we actually showed the relevance of our work on wild boars to human medicine."
As a complement to Anderson's research, the second winner, Prof. Jorge Dybkowski from Rice University in California, USA, told about the nutritional value of wheat as shown by the genome research, which in plants is much greater and more diverse than in animals.
"We know wheat very well. Like animals, wheat also made its home 10,000 years ago, including in the Middle East. Today, everyone eats bread and each year around 650 million tons of wheat are grown all over the world. 20% of the calories we consume every day and more than - 20% of the proteins come from wheat. Wheat came from place to place through humans, and its adaptation to different environments was done through a very flexible gene."
"We tested many sequences of this gene, we have to remember that wheat has 3 times more genes than humans. We know that there are many variations of the gene. The genome of plants changes fantastically, every 5 million years, much more than in animals, so it is very difficult to measure This mechanism and the mutations that occur in it. Only recently were we able to see the sequences thanks to genome sequencing technology."
"We are particularly researching the genes that cause changes in the resistance of wheat. In a million years of evolution, some of the properties of wheat disappeared. The mother of wheat was found in Israel in the sixties. We took this plant and carried out its genetic mapping, together with researchers from the University of Haifa (including Prof. Assaf Disenfeld, who today is Professor at Tel Aviv University) we cloned these plants so we could study them (the original amount was small). Comprehensive genetic mapping of tens of thousands of plants, to find the gene that causes wheat to become non-functional. We discovered that if the gene is replaced with a normal gene, the protein and zinc content in the wheat kernel can be increased by 10%."
"It was a gene that controlled the process of the plant's death, and when the plant dies, it must send all the minerals back to the nucleus in an organized manner and from there to the soil. If you remove the gene, you delay the plant's death. We managed to insert the correct gene into the nucleus, and today it is already grown commercially in the USA." in and in Canada the improved wheat."
The Wolf Prize has been awarded since 1978 to scientists and artists. The 2014 Wolf Prize was won by nine scientists from five countries. The award winners will receive a cash grant of one hundred thousand dollars. Award winners:
• Prof. Jorge Dobchovski (University of Davis, USA), Prof. Leif Andersson (University of Uppsala, Sweden) and Prof. Joachim Messing (University of Potgers, USA) - Award in the field of agriculture

Just as there is an Ig Nobel Prize. We need an Israeli equivalent. And this has nothing to do with the researchers mentioned here.
An important impact on the world's food supply will be if they manage to restore or activate the genes for perennials in wheat, corn, etc.
Regarding genetic engineering in a person. You can learn from the parents of the Chinese basketball player Wu Ming. They are his friend. It is good to give birth to a basketball player. But subconscious preferences lead the person.
Regarding what Kobe claims, it is already true today that all the world records are under the influence of drugs. (All East German medals should be canceled). And about the matter of some types of people. No one person is like another.
Didn't Aharon Aharonson discover the Mother of Wheat at the beginning of the century?
In 20 years they will be playing in the human gardens just as they are playing in the tomato gardens today.
Stronger muscles, better vision and hearing and more.., many combinations, also from combining genes from the animal and plant world.
The splitting of the human species would come from genetic interference, not evolution, and it would have been much faster
Probably already in the next century we had several different species of humans.
The more Israel's position is established, and the more Israeli science gets stronger. The Wolf Prize will become more prestigious. And maybe even equal to the Nobel Prize. The Wolf Prize is named after Ricardo Wolf, who was a Zionist industrialist.
