Outline of Final Research Achievements

CLE25, a member of CLE peptide family, was added to the root-inducing medium and found to inhibit growth of ‘Hiratanenashi’ persimmon root. The treatment after the formation of root primordia was more effective than that at the start of the root induction. Microscopic observations revealed that the cell division of the cortical tissue in the treated roots was inhibited so that the roots were thinner. The root-inducing medium with CLE25 inhibited elongation of roots of ‘Pino Noir’ grape, whereas the roots did not become thin. CLE25 treatments to shoot apical meristems of ‘Hiratanenashi’ and ‘Pino Noir’ had no effect on their growth. As for CLE14, another plant peptide hormone, the treatment to Arabidopsis seedlings reduced in primary root length and induced excess root hair formation.
