Gene-modified silkworms spin natural six-color silk
A fine map of the silkworm genome has been successfully drawn. At the Southwest University Silk Culture Festival yesterday, Professor Xia Qingyou from the School of Biotechnology of the school revealed the good news. It is understood that this scientific research project was jointly completed by Chinese and Japanese scientists.
Chinese and Japanese experts worked together to overcome difficulties
According to Xia Qingyou, chief scientist of the silkworm gene project team of the National “973” Program of Southwest University and professor of Southwest University, the silkworm genome framework map It has been announced a long time ago, but in order to figure out which gene mutation occurs in silkworms and how to solve it, we must rely on a detailed map of the genome to find the value of each gene. According to reports, in the past five years of research, the project team has mastered 2,670 trait markers of more than 600 varieties of silkworms, and thus conquered the gene cloning technology of silkworms. In cooperation with Japanese scientists, biological information was used to Using a new method of learning, 16,329 genes in the silkworm were successfully obtained and a detailed map of the silkworm genome was drawn. It is understood that silkworms are very similar to humans in terms of their basic life system, material metabolism, energy metabolism and genetic methods. Through gene cloning technology and the successful drawing of precise genome maps, it can help humans in disease control and the development of new drugs. research has a significant impact.
Natural colored cocoons appear
Yesterday, at the opening of the Silk Culture Festival, a picture of “Chang’e flying to the moon” made of colorful cocoons is the gene of the silkworm A result of the research. These colorful cocoons have not been processed at all. Instead, the genes of the silkworms have been changed through the silkworm genome framework map drawn by Southwest University. During the silkworm raising process, no special pigments are fed, let alone dyeing after cocooning, before they are spit out. Natural golden, goose yellow, green, pink, white, ocher silk, and never fade. According to He Songzhen, the classmate in charge of this cultural festival, this is the first time that colorful cocoons have gone out of the laboratory to meet with students. At the scene, the traditional silk reeling and silk pulling demonstrations also attracted quite a lot of attention.
