快速细胞壁软化导致捕蝇草闭合，这一成果由法国艾克斯-马赛大学Yol Forterre团队经过不懈努力而取得。相关论文于2026年6月11日发表在《科学》杂志上。

通过现场液压和机械测量，小组确定了驱动这种转变的马达。封闭发生得太快，无法用水运输来解释，这揭示了一种独特的非水力机制：表皮细胞壁迅速（约一秒钟）软化，释放储存在陷阱中的弹性能量。这代表了在植物中报道的最快的壁力学调节。他们的发现揭示了一种基于材料特性动态调节的植物运动模式，提出了无细胞、仿生驱动的原理。

据悉，植物可以在没有细胞的情况下快速移动，就像Venthem捕蝇草的捕捉叶一样——这是植物生物力学中一个长期存在的难题。圈闭闭合涉及弹性不稳定性，但主动机械驱动仍然是未知的。

Abstract: Plants can move rapidly without muscles, as seen in the Venus flytrap’s snapping lobes—a long-standing puzzle in plant biomechanics. Trap closure involves an elastic instability, but the active mechanical driver has remained elusive. Using in situ hydraulic and mechanical measurements, we identified the motor driving this transition. Closure occurs too quickly to be explained by water transport, revealing a distinct, nonhydraulic mechanism: a rapid (about one second) softening of the epidermal cell wall, releasing elastic energy stored in the trap. This represents the fastest modulation of wall mechanics reported in plants. Our finding reveals a mode of plant motility based on dynamic tuning of material properties, suggesting principles for muscle-free, bioinspired actuation.
