三菱化学生命科学研究所微生物化学研究室的坂口健二主任研究组在微生物中首次发现了充当运载基因任务的新奇的线状质体。质体在一般情况下呈环状,而线状质体只有在玉米的雄蕊里才能见到。按每一细胞来说较比普通质体的数多,如能巧妙地加以利用,对新抗生物质的发现是有用的,这一事实引起了人们的注意。在生物细胞里,作为遗传基因(DNA)集合体的核,外侧有质体,也叫核外基因。美国斯坦福大学克 The research team led by Sakagami Kenji, director of the Microbiology Laboratory at the Mitsubishi Chemical Institute of Life Sciences, discovered for the first time in the micro-organism novel novelty plastids that serve as genetic tasks. Plastids are generally ring-shaped, whereas plastids are only visible in the stamens of corn. The fact that the number of cells per cell is more than the number of ordinary plastids, and if cleverly utilized, is useful for the discovery of new anti-biotic substances. This fact has aroused people’s attention. In biological cells, as the nucleus of a collection of genetic (DNA) aggregates, there are plastids on the outside, also called extranuclear genes.
