Gene expression in opening and senescing petals of morning glory (Ipomoea nil) flowers (2007)

Yamada, T., Ichimura, K., Kanekatsu, M.

We isolated several senescence-associated genes (SAGs) from the petals of morning glory (Ipomoea nil) flowers, with the aim of furthering our understanding of programmed cell death. Samples were...

Relationship between petal abscission and programmed cell death in Prunus yedoensis and Delphinium belladonna (2007)

Yamada, T., Ichimura, K.

Depending on the species, the end of flower life span is characterized by petal wilting or by abscission of petals that are still fully turgid. Wilting at the end of petal life is due to programmed...

DNA degradation and nuclear degeneration during programmed cell death in petals of Antirrhinum, Argyranthemum, and Petunia (2006)

Yamada, T., Ichimura, K.

Programmed cell death (PCD) was studied in the petals of Antirrhinum majus, Argyranthemum frutescens, and Petunia hybrida, using DNA degradation and changes in nuclear morphology as parameters. The...

Nuclear fragmentation and DNA degradation during programmed cell death in petals of morning glory (Ipomoea nil) (2006)

We studied DNA degradation and nuclear fragmentation during programmed cell death (PCD) in petals of Ipomoea nil (L.) Roth flowers. The DNA degradation, as observed on agarose gels, showed a large...

Measurement of Neutrino Oscillation with KamLAND: Evidence of Spectral Distortion (2005)

Araki, T., Eguchi, K., Enomoto, S., Furuno, K., Ichimura, K., Ikeda, H., ...

We present results of a study of neutrino oscillation based on a 766 ton/year exposure of KamLAND to reactor antineutrinos. We observe 258 [overline nu ]e candidate events with energies above 3.4 MeV...

Comparative study of mixed monolayers of a calixarene with a fatty acid and a non-amphiphilic nematic liquid crystal (2000)

Nannelli, F., Fazio, V. S. U., Matsuzawa, Y., Komitov, L., Ichimura, K.

Many nematic liquid crystals (NLCs) lack a polar headgroup and thus are not able to form stable monolayers at the air/water (a/w) interface. A way to obtain monomolecular films of these compounds is...

Anisotropic superconducting gap of Bi2Sr2CaCu2O8 : tunneling spectroscopy with STM (1993)

Nomura, K., Ichimura, K.

The tunneling conductance was measured in the superconducting phase of Bi2Sr2CaCu2O8 with use of the STM and the temperature dependence of magnetic field penetration depth was also investigated by...
