一种群居性的阿米巴(Dictyostelium discoideum)可在两种形态间转换,一种是孤立的单细胞生物,另一种是高等真核生物典型的细胞分异和协作的多细胞形式,使其成为了解细胞信号传导和分异方式的一种关键模式生物。由德国、英国和美国等国科学家协作完成了这种变形虫的完整基因组序
A dominant group of Dictyostelium discoideum can switch between two forms, one is isolated single-celled organisms and the other is a multicellular form typical of higher eukaryotes that differentiate and collaborate It becomes a key model organism for understanding cell signaling and differentiation patterns. The complete genome sequence of this amoeba has been completed by scientists from Germany, the United Kingdom and the United States
