Symmetry breaking and re-establishment is an important developmental process that occurs during the development of multicellular organisms. A new report determines that transcription factors regulate a symmetry transition event in plants by modifying the direction of auxin transport. This provides one of the first mechanistic descriptions of a transition from bilateral to radial symmetry in plants.
对称性破缺与重建是多细胞生物发育过程中的一个重要的发育过程。一项新的研究报告表明，转录因子通过改变生长素运输的方向来调节植物中的对称转换事件，这为植物从双边对称到辐射对称的转变提供了第一个机制描述之一。
