Abstract
A time-dependent mechanism mediated by SPL9 highlights how age-related growth reprogramming influences leaf shape modifications in simple- and complex-leaved, related plants. Extending cell proliferation and delaying differentiation drives the mechanism, offering insights into the shared developmental processes underlying leaf form diversification.
摘要
由 SPL9 介导的时空调控机制突出了与年龄相关的生长重编程如何影响简单叶和复叶相关植物的叶片形状改变。延长细胞增殖并延缓分化推动了这一机制，为叶片形态多样化的共同发育过程提供了新的认识。
