1.1当在半固体表面上生长时，P. vortex通过产生旋转模块（称为漩涡）来组织其菌落，每个模块由许多细胞组成，这些细胞用作整个殖民地的构建块[1-17]，如图S1所示。每个漩涡都由许多细胞组成，这些细胞以大约10微米/秒的速度集体围绕它们的共同中心聚集（见电影S1）。根据它们在殖民地中的位置，漩涡的大小从数千到数百万个细菌不等。涡旋中的细胞复制，涡旋的大小扩大，并作为一个单位向外移动，留下一条运动但通常不复制的细胞的痕迹-涡旋分支。旋涡的动力学过程非常复杂，包括旋涡的吸引、排斥、合并和分裂。然而，从这个复杂的，看似混乱的动态，一个复杂的，但非任意组织的殖民地出现。每个漩涡中的细菌也具有高度的长度变异性。透射电子显微镜（TEM）观察显示，细长的细胞有几个染色体。
1.1 Complex modular organization When grown on semi-solid surfaces, P. vortex organize its colonies by generating rotating modules (termed vortices), each consisting of many cells, which are used as building blocks for the colony as a whole [1-17] as is illustrated in Figure S1. Each vortex is composed of many cells that swarm collectively around their common center at about 10 micron/sec (see Movie S1). The vortices vary in size from tens to millions of bacteria, according to their location in the colony. The cells in the vortex replicate, and the vortex expands in size and moves outward as a unit, leaving behind a trail of motile but usually non-replicating cells – the vortex branch. The dynamics of the vortices is quite complicated and includes attraction, repulsion, merging and splitting of vortices. Yet, from this complex, seemingly chaotic dynamics, a colony with complex but non-arbitrary organization emerges. The bacteria in each vortex also have high length variability. Transmission electron microscope (TEM) observations revealed that the elongated cells have several chromosomes.
