Abstract
An increase in GDH activity has been established in the first six hours after plants are exposed to hypoxic conditions, which ensures the formation of an adaptive response of cellular metabolism to the lack of oxygen in the cell. A difference in the transcriptional activity of homologous GDH-1 genes in wheat leaves under stress conditions was shown. An increase in the mRNA content of the GDH-1(5A) gene in wheat leaves after plants are exposed to hypoxic conditions is observed in the first hours of the experiment, which correlates with a change in the catalytic activity of glutamate dehydrogenase. Regulation of this gene is carried out by the transcription factor HIF, the specific landing site of which is found in the transcription initiation site of the promoter of this gene.
