Abstract
Analysis by real-time PCR of single and double insertion mutants of A. thaliana with inactivated cytokinin receptor genes showed that the level of transcripts of some of plastid genes during skotomorphogenesis depended on the state of functionally active receptor AHK3. The cytokinin-regulated plastid encoded genes involved the housekeeping genes (rpoB and accD) and the genes for photosynthetic proteins (ndhA, psbA, atpB, and psaA). However, the absence of hormone activation of plastid encoded genes engaged in the translation of plastid proteins, rRNA (rrn16), and tRNA (trnE), indirectly indicate the disruption of the synthesis of chloroplast proteins in the dark.
