A potential mechanism of light regulation of the succinate dehydrogenase (SDH) expression in Arabidopsis thaliana leaves was studied. As was shown by dot-hybridization and polymerase chain reaction in real time (RT-PCR), the SDH mRNA level in wild-type Arabidopsis thaliana plants changed depending on light conditions. The level of SDH mRNA in darkness was higher than in the light. The analysis of Arabidopsis thaliana plants carrying the mutant genes of phytochromes A and B showed that phytochrome A was involved in the regulation of the SDH enzyme activity. The active form of phytochrome A suppressed the SDHI-2 gene expression, and that resulted in decreasing activity of SDH.
