Cerium(IV) ion is attached to the 5′-end of a 19-mer DNA by use of iminodiacetate ligand. At pH 7.2 and 30 °C, the hybrid selectively cuts a 40-mer DNA, which has 19-mer sequence complementary with the DNA in the hybrid, at the target site (the 3

DNA hydrolysis by Ce(IV) effectively proceeds both in the presence and in the absence of molecular oxygen. Addition of hydrogen peroxide induces undesired oxidative side-reactions and suppresses the hydrolysis. Participation of molecular oxygen and h

Novel ruthenium complexes coordinated with various chiral diphosphines were synthesized by reactions of polynuclear [RuCl2(cycloocta-1,5-diene)]n with the respective diphosphines in the presence of triethylamine. The compositions of the complexes thu

The ruthenium trihydride complex [RuH3(dppf)2]PF6 (dppf = 1,1′-bis(diphenylphosphino)ferrocene) was prepared by contacting [RuH(dppf)2]PF6 with H2 gas, and its molecular structure was determined by the X-ray crystallography. The four phosphorus ato

Cerium(III) chloride efficiently hydrolyzes DNA at pH 7 under aerobic conditions. A titration study showed that Ce(III) is oxidized to Ce(IV) in the reaction mixture and the resultant Ce(IV) is responsible for the DNA hydrolysis.

Effects of auxins and cytokinins on callus induction of Stevia rebaudiana Bertoni and root differentiation from it was investigated. As for the auxin, 1-naphthaleneacetic acid (NAA) encouraged the callus induction more than 3-indoleacetic acid (IAA).
