Phenotypic diversity of flowering plants stems from common basic features of the plant body pattern with well-defined body axes, organs and tissue organisation. Cell division and cell specification are the two processes that underlie the formation of a body pattern. As plant cells are encased into their cellulosic walls, directional cell division through precise positioning of division plane is crucial for shaping plant morphology. Since many plant cells are pluripotent, their fate establishment is influenced by their cellular environment through cell-to-cell signaling. Recent studies show that apart from biochemical regulation, these two processes are also influenced by cell and tissue morphology and operate under mechanical control. Finding a proper model system that allows dissecting the relationship between these aspects is the key to our understanding of pattern establishment. In this review, we present the embryo as a simple, yet comprehensive model of pattern formation compatible with high-throughput quantitative assays.
开花植物的表型多样性源于具有明确身体轴、器官和组织组织的植物体模式的共同基本特征。细胞分裂和细胞特化是形成身体模式的两个过程。由于植物细胞被包裹在它们的纤维素壁中，通过精确定位分裂平面进行定向细胞分裂对于塑造植物形态至关重要。由于许多植物细胞是多能的，它们的命运确立通过细胞间信号传导受到其细胞环境的影响。最近的研究表明，除了生化调节外，这两个过程还受到细胞和组织形态的影响，并在机械控制下运作。找到一个合适的模型系统来剖析这些方面之间的关系是我们理解模式建立的关键。在这篇综述中，我们将胚胎作为一个简单而全面的模式形成模型，它与高通量定量分析兼容。
