The morphology of a plant is determined by the network of its cell walls. Unlike in other multicellular eukaryotic organisms plant cells are immobilized by cellulosic walls and formed in the positions were they are needed during development. Thus, the shape of a cell is established by its surrounding walls and critically depends on the orientation of cell division and the direction of cell expansion, requiring meticulous spatial control of cell cycle and cell division planes. Both, cell division and expansion are controlled by the cytoskeleton, which facilitates the distribution and organization of a variety of cellular components, including the confined deposition of cell wall material. The cytoskeleton-dependent mechanisms governing the establishment, recognition and maintenance of the division plane throughout cell division are yet poorly understood. Our goal is to elucidate these mechanisms using genetic tools along with confocal imaging.

植物的形态取决于其细胞壁的网络。与其他多细胞真核生物不同，植物细胞被纤维素壁固定，并在发育过程中需要在位置形成。因此，细胞的形状是通过其周围的壁建立的，并且非常取决于细胞分裂的方向以及细胞膨胀的方向，需要对细胞周期和细胞分裂平面的细致空间控制。细胞分裂和膨胀都受细胞骨架控制，这促进了各种细胞成分的分布和组织，包括细胞壁材料的密闭沉积。依赖于整个细胞分裂的划分平面的建立，识别和维护的细胞骨架依赖机制尚不清楚。我们的目标是使用遗传工具以及共共聚焦成像阐明这些机制。
