Research of Special Interest
Functions of plant cytoskeleton proteins.
The functions of Arabidopsis Kinesin AtKP1 and cotton kinesin GhKCH2 are studied at the genetic, cellular, and biochemical levels. Both AtKP1 and GhKCH2 have CH domain, a specific domain for plant microfilament-binding proteins. It is significant to uncovering the special roles of microtubule-based motor proteins, AtKP1 and GhKCH2, during plant growth and development.
