Molecular control of division site establishment in plants

植物的形态是由其细胞壁的网络决定的。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的位置形成。因此，细胞的形状是由其周围的壁建立的，并且关键地取决于细胞分裂的方向和细胞扩增的方向，需要对细胞周期和细胞分裂平面进行细致的空间控制。细胞分裂和扩张都由细胞骨架控制，细胞骨架促进各种细胞组分的分布和组织，包括细胞壁物质的受限沉积。在整个细胞分裂过程中，细胞分裂素依赖的分裂平面的建立、识别和维持机制还知之甚少。我们的目标是阐明这些机制，使用遗传工具沿着共聚焦成像。

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.
