Owing to the sessile nature of their lifestyle, plants have to respond to a wide range of signals, such as the force of the wind or the impedance of the soil, to entrain their development to prevailing environmental conditions. Indeed, mechanically responsive growth has been documented in plants for many years but new work on lateral root formation strongly supports the idea that biophysical forces can elicit complete de novo developmental programs. In addition, only recently have molecular candidates for plant mechanosensors emerged. Such advances in understanding plant mechanoresponsive development have relied heavily on comparison with mechanosensors characterized in organisms such as Saccharomyces cerevisiae and Escherichia coli, but key questions remain about the cellular basis of the plant mechanosensory system.
由于植物固着的生活方式，它们必须对各种信号做出反应，如风的力量或土壤的阻力，以便使其发育与当前的环境条件同步。事实上，植物中机械响应性生长已被记录多年，但关于侧根形成的新研究有力地支持了生物物理力能够引发全新发育程序的观点。此外，直到最近植物机械传感器的分子候选物才出现。在理解植物机械响应性发育方面的这些进展在很大程度上依赖于与酿酒酵母和大肠杆菌等生物体中已明确的机械传感器进行比较，但关于植物机械传感系统的细胞基础仍存在关键问题。
