Abstract
We will report our IPA gene expression analysis results on the effect of metal hydride ion water on plants. At previous meetings we made presentations regarding the ion binding properties of metal hydrides, such as CaH2 and the ability to control plant growth and promote life extension, blooming and so on. We have shown the phenomenon whereby cut flowers treated in ionized hydrogen water, which was made from ion binding metal hydride, continued growing with increased height as well as the continual blooming of new flowers. The ion binding property of metal hydride has the potential to control ion channels such as calcium. This time we conducted gene expression analysis using a DNA array method to study plant reactions in metal hydride treated water. Results indicate up-regulation of peroxidase 40, CYP71B36 and GRP16. However, mRNA such as thioredoxin-dependent peroxidase 2, vitamin C permease family protein, and domains linked to heavy metal containing proteins, showed down-regulation.
