控制植物器官大小的机制综述。植物生长对人类文明具有无与伦比的重要性,但我们才刚刚开始了解其机制。植物器官的生长速率和最终大小受遗传和环境因素的制约。调控输入在两个控制点起作用:增殖;以及增殖和分化之间的过渡。细胞自主和短程生长信号分生组织域内的行为,而从分化的部分增殖细胞的扩散信号提供几何形状和大小和通道环境输入的措施。
A review of the mechanisms that control organ size in plants. Plant growth has unparalleled importance for human civilization, yet we are only starting to gain an understanding of its mechanisms. The growth rate and final size of plant organs is determined by both genetic constraints and environmental factors. Regulatory inputs act at two control points: on proliferation; and on the transition between proliferation and differentiation. Cell-autonomous and short-range growth signals act within meristematic domains, whereas diffusible signals from differentiated parts to proliferating cells provide measures of geometry and size and channel environmental inputs.
