Roles of novel mechanosensitive calcium channels in perception of physical stimuli in Arabidopsis

本研究以拟南芥为材料，研究了机械敏感性钙通道MCA1和MCA2在物理刺激感知中的作用。这两种蛋白质是我们的研究小组在2007年首次报道的。在这里，我们已经表明，MCA 1，这是在根尖表达，是参与感知琼脂培养基的硬度。相比之下，MCA 2在那里没有表达，不负责感知它。此外，我们已经证明MCA 1和MCA 2都在感知冷休克中发挥作用。

In this project, we studied on the roles of novel mechanosensitive calcium channel candidates, MCA1 and MCA2, in perception of physical stimuli in Arabidopsis. The two proteins were first reported by our research group in 2007. Here, we have shown that MCA1, which is expressed at the root tip, is involved in perception of hardness of agar medium. By contrast, MCA2, which is not expressed there, is not responsible for perception of it. In addition, we have shown that both MCA1 and MCA2 function in perception of cold shock.
