| Outline of Final Research Achievements |
The plasma membrane (PM) H+-ATPase in plants mediates numerous important physiological processes, such nutrient uptake in roots, stomatal opening, and phloem loading. However, the molecular and regulatory mechanisms of this enzyme is still remains unknown. In this study, we investigated regulatory mechanism and physiological roles of PM H+-ATPase in plants and found that PM H+-ATPase is regulated photosynthesis-dependent manner in Arabidopsis and Klebsormidium, and that PM H+-ATPase in rice roots are activated by one of nutrient silicon, which has important role for the stress tolerant in rice. Furthermore, we found that plant hormones brassinosteroid and auxin activate PM H+-ATPase in etiolated hypocotyl in Arabidopsis through their receptors, BRI1 and TIR1, respectively. These results provide important information for understanding molecular mechanism and physiological role of PM H+-ATPase in plant growth.
