Light-Induced Changes of Membrane Potential in Guard Cells of Vicia faba (1983)
Ishikawa, Hideo, Aizawa, Hiroko, Kishira, Hideo, Ogawa, Teruo, Sakata, Makoto
Guard cells of Vicia faba maintain a negative membrane potential (MP). They hyperpolarize in the light and depolarize in the dark. The light-induced hyperpolarization is eliminated by adding the...

In this study we investigated the kinetics of the gravitropic response of the Arabidopsis mutant rgr1 (reduced root gravitropism). Although the rate of curvature in rgr1, which is allelic to axr4,...
Kinetics of Constant Gravitropic Stimulus Responses in Arabidopsis Roots Using a Feedback System12
Mullen, Jack L., Wolverton, Chris, Ishikawa, Hideo, Evans, Michael L.
The study of gravitropism is hindered by the fact that as a root responds, the gravitational stimulus changes. Using a feedback system to connect a rotating stage platform to a video digitizer...
