| Outline of Final Research Achievements |
GmTDF-5, a soybean gene encoding a protein of unknown function, enhances salt tolerance of transgenic Arabidopsis plants. In this study, we investigated how GmTDF-5 protein plays a role in molecular response and tolerance strategies of soybean under high-salt stress. The results suggested that (1) GmTDF-5 protein is controlled functionally under ubiquitin-proteasome degradation system (UPS), (2) the UPS regulation to GmTDF-5 protein is involved in the increased salt tolerance of the transgenic Arabidopsis plants, and (3) transcriptional activation of GmTDF-5 gene might be related to increased salt tolerance of several soybean species in the Japanese genetic resources.
