Coordination of organ identity and symmetry establishment in flower organs

几何特征存在于植物、动物和真菌等生物体内。多细胞生物共有的一个显著几何特征是，相同的身体部位围绕一个假想的轴线分布，这被称为对称性。生物学中的对称不仅是一个非常迷人的过程，而且是必要的，因为它为器官的形状和功能提供了基础。因此，对称的建立和打破最终支持适应和进化优势。尽管具有基本的重要性，但在多细胞生物的发育过程中，一种对称，即双边和径向对称，是如何建立和/或转换的，人们仍然知之甚少。对称基础、体轴极性和细胞/组织命运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建立协调，最终目的是发现植物器官发生过程中建立地面对称型所需的遗传、分子和细胞原理。

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.
