Molecular genetic analysis of plant organ size control

什么控制大小是基础生物学和应用生物学中的一个重要问题，但调节这种控制的内在机制尚未被很好地理解。在本研究中，我们旨在揭示控制植物器官大小的分子机制。以拟南芥为模型系统，我们发现了调控细胞增殖、细胞扩张和细胞分化的新基因，并为植物如何通过调节这些细胞过程来控制器官大小提供了新的分子见解。

What controls size is an important question in both basic and applied biology but the intrinsic mechanism mediating this control is not well understood. In this study, we aimed at unraveling the molecular mechanism controlling organ size in plants. Using Arabidopsis as a model system, we identified novel genes regulating cell proliferation, cell expansion and cell differentiation, and provided new molecular insights into how plants control organ size through modulating these cellular processes.
