Recently, Greenpeace published a report on the crusade against transgenic papaya.

Reports that contain domestic papaya produce antibiotics resistance genes. Eat the papaya, aggravate the problem of antibiotic resistance. This is a report of the Bureau, therefore, necessary for their interpretation of a scientific nature.

Mentioned in the report, and allow the promotion of papaya, Guangdong Province, is a genetically modified variety of disease-resistant technologies.

However, this kind of resistance to papaya is not of antibiotic resistance genes. Antibiotic resistance genes to plants itself does not have any benefits. Occurs in plants, because it is a good helper for scientists. Scientists use of antibiotic resistance genes for transgenic work easier. Genetically modified, only a small part of the cell can obtain new genes. Find new genes into cells is very difficult, as if you went to the station to meet a stranger.

In the bustling crowd, how to find a stranger is not easy.

? We can advance and strange guests about good: guest you take a Durian. So, as long as you follow the smell of durian, find one with a diameter of about 3 meters, nobody dares to slightly over the region — — station in Central the creased nose, certainly is afar strange guests. Scientists are let into the plant body of target gene took a position of "Durian" — antibiotic gene, and through it to find that accepted the new genes in cells. This antibiotic gene has a named marker gene, that is, the usefulness of this gene is to target genes do a tag, so that it can and other genes.

Scientist extraordinaire, used to mark the antibiotic gene, and how can become a thorn in environmental organizations?

In this report, there is such a saying: "research shows that genetically modified foods antibiotic resistance

genes may by transfection of intestinal bacteria, causing a human resistance to these antibiotics, antibiotic resistance. "(This sentence is not stringent, antibiotics kill the bacteria is not a person, therefore is not possible resistance to antibiotics. ) I followed an article from the famous scientific journal Nature · biotechnology law reference literature. Slightly participated in scientific research work of the people know, the one conclusion or conjecture, plus an information source, is a standard for the presentation of scientific papers. This makes it easier for each peer to verify the reliability of its conclusions, the rationality of the suspect. Therefore, the report of this sentence seems to be talking to the scientific, academic scientists to study the Visual.

But this source not verified.

Read this article, published in 2000, the paper finds that it would not be able to prove that "Greenpeace" by deciding the reasonableness of the assumptions. In fact, this paper introduces a new method, you can put the marker gene from transgenic tobacco remove out. The whole article has one and only one sentence involves a foreign gene transfection of intestinal bacteria. This sentence translated like this: "into the gene have theoretical risk level to intestinal bacteria. " In that sentence before the thesis the author describes the origin of this theoretical assumption — it is not in a scientific experiment data, but from consumer groups on food resistance gene widely distributed. The "Green peace" is playing consumer spokesperson. Scientists just cursory reference "Greenpeace" point of view, "Greenpeace" think scientists in support of their view that it was absurd? also, so-called scientific studies prove that where? as reason to crusade against genetically modified food, and more than 800 years ago to the name of the "unwarranted" kill the rows for that specific Yue Fei!

Although there is no scientific evidence to support t

he genetically modified food in theory of risk, scientists in order to address consumers ' concerns, has developed several ways to remove marker genes in transgenic plants, this report refers to the natural · biotechnology law literature is one example. As technology evolves, we are the future of genetically modified food, you will no longer have the antibiotic resistance marker genes.
