植物在生长发育过程中会受到各种各样的机械刺激。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至关重要的作用。在过去的十年中,动物的机械敏感离子通道Piezo的研究取得了重大进展。事实证明,对机械力的感知在动物的各种生理过程中是必不可少的。然而,关于其同系物在植物中的功能仍然知之甚少。本研究通过对模式植物拟南芥AtPiezo基因功能的研究,发现AtPiezo基因在植物根冠对机械力的感知中发挥重要作用,并与Ca2+的流动有关。这些发现使我们能够从植物的角度理解AtPiezo的功能,并为植物根冠响应机械刺激的机制提供新的见解。
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 AtPiezo gene in the model plant Arabidopsis thaliana, we found that AtPiezo plays a role in the perception of mechanical force in plant root cap and the flow of Ca2+ 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.
