Abstract

How do plants make species-specific leaves and flowers with stereotypical size and shape? A new study in Developmental Cell finds that local spatiotemporal variability in cell growth rate is essential for robustness in organ geometry control, and reactive oxygen species act to suppress this local heterogeneity during organ maturation.

摘要

植物如何形成具有特定大小和形状的种特异性叶片和花朵？发育细胞杂志上的一项新研究发现，细胞生长速率的局部时空变异性对于器官几何形状控制的稳健性至关重要，而活性氧物质在器官成熟过程中会抑制这种局部异质性。
