Plants encounter a variety of mechanical stimuli during their growth and development. It is currently believed that mechanosensitive ion channels play an essential role in the initial perception of mechanical force in plants. Over the past decade, the study of Piezo, a mechanosensitive ion channel in animals, has made significant progress. It has been proved that the perception of mechanical force in various physiological processes of animals is indispensable. However, little is still known about the function of its homologs in plants. In this study, by investigating the function of the gene in the model plant , we found that plays a role in the perception of mechanical force in plant root cap and the flow of Ca is involved in this process. These findings allow us to understand the function of AtPiezo from the perspective of plants and provide new insights into the mechanism of plant root cap in response to mechanical stimuli.
植物在生长发育过程中会遇到各种机械刺激。目前认为，机械敏感离子通道在植物对机械力的初始感知中起着重要作用。在过去的十年中，对动物中的机械敏感离子通道 Piezo 的研究取得了重大进展。已经证明，动物各种生理过程中对机械力的感知是不可或缺的。然而，关于其在植物中的同源物的功能仍然知之甚少。在这项研究中，通过研究模式植物 中的 基因的功能，我们发现 在植物根冠对机械力的感知中发挥作用，并且该过程涉及到 Ca 的流动。这些发现使我们能够从植物的角度理解 AtPiezo 的功能，并为植物根冠对机械刺激的响应机制提供新的见解。
