Geometric features are embedded in the body of living organisms such as plants, animals, and fungi. Aremarkable geometric feature shared by multicellular organisms is the distribution of identical bodyparts around an imaginary axis, known as SYMMETRY. Symmetry in biology is not only a veryfascinating process to be understood, but also a necessity as it provides the foundation for organshape and function. Thus, symmetry establishment and breaking ultimately support adaptation andevolutionary advantages. Despite its fundamental importance, how a type of symmetry, i.e., bilateraland radial symmetry, is established and/or switched during the development of multicellularorganisms is still poorly understood. Symmetry foundation, the polarity of the body-axes, andcell/tissue fate determination are intertwined processes during multicellular development of bothanimals and plants. This project will investigate how tissue/organ identy and polarity are coordinatedwith symmetry establishment during the development of flower organs in Arabidopsis thaliana, withthe final aim to discover the genetic, molecular and cellular principles necessary to set up a groundsymmetric type during plant organogenesis.

几何特征嵌入到生物体内，如植物、动物和真菌。多细胞生物体共有的一个显著的几何特征是完全相同的身体部位围绕一个假想的轴分布，称为对称性。生物学中的对称性不仅是一个非常令人着迷的理解过程，而且也是一种必然性，因为它为组织形态和功能提供了基础。因此，对称性的建立和打破最终支持适应和进化优势。尽管对称性具有基本的重要性，但在多细胞生物的发育过程中，如何建立和/或转换一种对称性，即双边和径向对称性，仍然知之甚少。对称性基础、体轴的极性和细胞/组织命运的决定是动植物多细胞发育过程中相互交织的过程。本项目将研究在拟南芥花器官发育过程中，组织/器官的同一性和极性如何与对称性的建立相协调，最终目的是发现在植物器官发生过程中建立地对称型所必需的遗传、分子和细胞学原理。
