| Outline of Final Research Achievements |
Arabidopsis helical growth mutants include those which twist to form right- or left-handed helices in their epidermal cell files and those twist in random directions. Microtubule (MT)-related mutants show fixed handedness. To test a helical growth model of axial organs, MT-related and -unrelated growth regulating genes are expressed in cortex or epidermis of Aarbidopsis roots, by using cell layer-specific promoters. When MT-related genes are expressed, twisting phenotypes partially agree with the model, but specificities of the promoters and inter-cell layer movement of the expressed proteins make interpretation difficult. Experiments involving MT-unrelated genes are on-going.
