Literature summary for 1.4.1.2 extracted from
- The two senescence-related markers, GS1 (cytosolic glutamine synthetase) and GDH (glutamate dehydrogenase), involved in nitrogen mobilization, are differentially regulated during pathogen attack and by stress hormones and reactive oxygen species in Nicotiana tabcum L. leaves (2006), J. Exp. Bot., 57, 547-557.
Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| ethylene | increase in the expression of GDH and the aminating GDH activity | Nicotiana tabacum |  |
| H2O2 | increase in the aminating GDH activity correlating with gene expression, in a dose-dependent manner | Nicotiana tabacum | |
| jasmonic acid | increase in the expression of GDH and the aminating GDH activity | Nicotiana tabacum | |
| additional information | cryptogein and Onozuka R10 induce GDH expression, GDH activity is correlated with GDH expression and the GDH enzyme preferentially catalyses the aminating reaction | Nicotiana tabacum | |
| additional information | GDH mRNA accumulates preferentially in plants inoculated with the avirulent Pseudomonas syringae pv. syringae CFBP3077 (hrp+) and the virulent Pseudomonas syringae pv. tabaci CFBP1503 strains, induction of GDH expression by bacterial infection dependeds on the hrp- genotype, but not on the virulence/avirulence genotype | Nicotiana tabacum | |
| additional information | leaf GDH aminating-activity increases, whereas deaminating-activity is not affected by infection with viruses CMV, TEV, and PVY | Nicotiana tabacum | |
| salicylic acid | increase in the expression of GDH | Nicotiana tabacum | |
Application
| Application | Comment | Organism |
|---|---|---|
| agriculture | GDH genes involved in leaf senescence are also a component of the plant defence response during plantpathogen interaction, GDH behaves like a non-specific stress-related gene | Nicotiana tabacum |
