Research Abstract |
It was elucidated that the N-terminus conserved region of PHS1 showed the activities of dissipation of cortical microtubules in Arabidopsis. The region phosphorylated PHS1 oneself andα-tubulins, directly. Moreover the activities ware repressed by the C-terminus region of PHS1. Thus, these results indicated the possibility that the existence or dissipation of cortical microtubules may be controlled by PHS1 protein, which possesses both kinase domain and phosphatase domain. It was also shown that the PHS1-mediated phospholylation ofα-tubulins was induced by salt stress.
