Slowly many of the species are being freed from cultivating without the authorization of the U.S. Department of Agriculture (USDA). Freeing them from being cultivated without the authorization will be helping in higher cultivation of the said products and thus will be enhancing their cultivating land.

A kind of special species which is being genetically engineered a type of mushroom is been freed from the regulation the same way by the U.S. Department of Agriculture (USDA). This means that further it can be cultivated and sold without the USDA been overseen over the matter. This has came to light after the recent news report being published online in Nature. In the similar way about 30 genetically modified organisms have been freed in a similar way by USDA.

Newer Technology of genetic editing: CRISPR-Cas9

The most special thing about the mushroom being edited is that it is the first species being edited using the technology being known as CRISPR-Cas9 which currently making waves in the field of genome is editing. It is being commonly known as the white button mushroom, which was being genetically engineered by Yinong Yang from the Pennsylvania State University by the use of the CRISPR-Cas9. This in particular engineered mushroom are not easily browned when they are sliced. This will be helping in improving the shelf-life by rendering them valuable commercially.

The coloring of the form of brownish in the mushroom is being caused by an enzyme being called as polyphenol oxidase (PPO). The above effect on the mushroom may be achived by the removing genetically their code of the enzyme. By this removal, Dr. Yang got successfully rid of one of the six PPO genes which reduced the enzymatic activity by 30 percent. The process quite didn’t introduced the foreign DNA by removal from the other viruses and bacteria. This process is perhaps the main reason behind why the mushroom is being given the green signal.

Advances in the BioTechnology

Cultivation of the genetically modified crops is one of the huge industry and is undergoing the massive rethink being undergoing the three-prolonged argument, with the industry on the side. The biologists over the another and activists also opposing it from the third. The US National Academy of Sciences, Engineering and Medicine will be meeting on 18th April for the discussion of the issue and will be bringing out a report for the prediction of the advances which will be made in the biotechnology products over the upcoming years.

There are also a kind of the whole spectrum of the rules in the countries around the world when it is being concerning to the research over the genetic engineering and the corresponding implementation of the results outside the lab. The case is being pointing out that of the kind of germline editing using the CRISPR over which research is being banned over many of the countries. Regarding the genetically modified crops the U.S is quite liberal and is likely to be more.

The organisms which are currently been given the green signal is involving some of the simple steps of editing which involves knocking off a set of the genes for the creation of the desired effect. With the corresponding advances in the technology more complex procedures are being about to be initiated and the complete process of the regulation of it will need to be reviewed as they happens.
