Scientists have created a moss that can grow on Mars - VIDEO PDF Print E-mail

A group of students from the University of Copenhagen is working on a project to create a genetically modified species of moss that can grow on Mars. According to Danish news agency Ritzaus Bureau, 9 students are trying to adapt to terrestrial plant extremely harsh conditions "red planet" in the hope that someday they will be useful when the idea of ​​colonizing Mars earthlings. For their experiment, the students chose moss species Physcomitrella patens, whose genome has been completely deciphered, and tried to give it a range of new features. The main objective was to make the plant frost resistance, as the poles of Mars at night the temperature can drop to minus 153 degrees Celsius, while the equator - to minus 60. For these purposes, was chosen gene spruce budworm (Choristoneura fumiferana) - species of moths, whose larvae are easily tolerate severe frosts, producing a natural analogue of antifreeze. Under laboratory conditions, it was also recreated other conditions of the Martian surface - oxygen-poor atmosphere, 95% consisting of carbon dioxide, as well as hard radiation. As a substitute of Martian soil was selected with volcanic soil of Hawaii, which closely resembles the composition of the Martian that a few years ago it was established by means of the rover Curiosity. Students say that we have achieved some success, and now better understand the challenges faced by those who ever try to grow plants in the open Martian soil. Thus, the composition of the Martian atmosphere was more fit for living plant organisms than it may seem at first glance. According to the project participants, the ability to grow living organisms in the Martian environment could solve a number of potential problems that may arise during its colonization. One of the most serious is the limit weight that can be lifted into orbit and deliver to another celestial body. Young Danes offer the option of a partial solution to this problem. Their moss or other living organism can be genetically programmed to produce chemical compounds which may be used as a vitamin supplement, seasoning or drugs such as resveratrol - substances which produce many plants for protection against pests, and which thus has an antitumor and antiinflammatory action, and strengthens the cardiovascular system. In the theory of moss can also be plastic, but out of it with the help of three-dimensional printing technology to create the necessary items colonists. Kopengagentskogo University Students recognize that their project is almost ripe for practical applications, but hope to find new scientific approaches to the future relocation from Earth to other planets has turned from a dream into reality. However, the Danish Technical University, Professor Jon Jorgensen indicate a problem that may put an end to the idea of ​​"plant factories". He stressed that the current international agreements is forbidden to deliver to other planets living organic matter, so as not to create a risk to the life that they could potentially exist. The results of the Danish students will demonstrate in Boston (USA) at the end of this month at the international competition in synthetic biology. Nearly 300 of the participating teams will bring to their projects of this new direction of genetic engineering, one of whose goals - to enable a person to create a living organism with a fully pre-specified properties.
