Outline of Final Research Achievements

CLE25, whose activity is higher than CLV3, a plant peptide hormone regulating development of the shoot apical meristem, was used in tissue culture of fruit trees. The roots from Japanese persimmon shoots growing in the medium supplemented with CLE25 were found to become thin, and the microscopic observation on the roots revealed that the number of cells in cortical layer decreased. However, the roots from grape shoots treated with CLE25 did not become thin, although their growth was inhibited by CLE25. We identified five CLV3-like genes from grape. Expression analyses showed that the five grape CLV3-like genes are expressed in leaves, stems, roots and axillary buds with significant differences in their levels of expression. The differential expression suggests that they play different roles in different organs and developmental stages.
