The mechanism of transduction of the phytochrome signal regulating the expression of succinate dehydrogenase in Arabidopsis has been investigated. Using the phytochrome mutants of Arabidopsis, it is demonstrated that the inhibition of succinate dehydrogenase in the light may result from the phytochrome A-dependent modulation of Ca²⁺ amount in the nuclear fraction of leaves. This leads to the activation of expression of the gene pif3 encoding the phytochrome-interacting factor PIF3, which binds to the promoter of the gene sdh1-2 encoding the SDHA subunit of succinate dehydrogenase and suppresses its expression. It is concluded that Ca²⁺ ions are involved in the phytochrome A-mediated inhibition of succinate dehydrogenase activity in the light |
