| Outline of Final Research Achievements |
Sucrose starvation treatment signi,cantly enhanced the expressions of GmbZIP53A, but not GmbZIP53B asparagine synthase (GmASN), proline dehydrogenase (GmProDH), and branched chain amino acid transaminase (GmBCAT). GmbZIP53-related immunoreactive signals were upregulated under severe starvation with sucrose starvation and protease inhibitors, while sucrose and sucrose starvation had no or marginal eects on the signal. Pro,les of induction of GmASN, GmProDH and GmBCAT3 under various nutrient conditions were consistent with the profles of GmbZIP53 protein levels but not with those of GmbZIP mRNA levels. These results indicate that GmbZIP53 proteins levels are regulated by posttranslational mechanism in response to severe starvation stress and that the increased protein of GmbZIP53 under severe starvation accelerates transcriptional induction of GmASN, GmProDH, and GmBCAT.
