| Research Abstract |
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.
