摘要植物与环境的相互作用受到植物内源信号和环境信号的微调。机械力是调节植物生长发育和塑造植物结构的重要外源刺激。研究表明，机械敏感离子通道在植物对机械信号的响应中起着至关重要的作用。动物Piezos是一组机械敏感的离子通道，其生物学功能已被广泛研究，并被揭示为正常生理过程所必需的。然而，动物Piezo基因的同源基因在植物中的功能知之甚少。我们最近发现AtPiezo在拟南芥响应机械力的根冠中起着重要的作用。在这里，我们进一步表明，AtPiezo在转录水平上对机械刺激做出反应。这些结果为Piezo参与植物的机械反应提供了额外的证据。
ABSTRACT The plant-environment interactions are finely tuned by plant endogenous signals and environmental cues. Mechanical forces serve as important exogenous stimuli regulating plant growth and development and shaping plant structures. Studies have shown that mechanosensitive ion channels play essential roles in the responses to mechanical signals in plants. The biological functions of animal Piezos, a group of mechanosensitive ion channels, have been extensively studied and revealed to be required for normal physiological processes. However, little is known about the functions of the homologous genes of animal Piezo genes in plants. We have recently pinpointed that AtPiezo plays an important role in the root cap in response to mechanical forces in Arabidopsis thaliana. Here, we further show that AtPiezo responds to mechanical stimuli at the transcriptional level. The results provide additional evidence for the involvement of Piezo in mechanical responses in plants.
