Bacterial species take on a wide variety of shapes, but the mechanisms by which specific shapes evolve have remained poorly understood. A recent study demonstrates that two Asticcacaulis species repurposed an ancestral regulatory protein to rewire the modules of stalk regulation, localization, and synthesis, thereby generating new shapes.
细菌物种呈现出各种各样的形状，但特定形状进化的机制一直未得到充分理解。最近的一项研究表明，两种Asticcacaulis细菌物种重新利用了一种祖先调节蛋白，以重新连接茎干调节、定位和合成的模块，从而产生了新的形状。
