| Beschreibung: | C4 photosynthetic plants have evolved from C 3 ancestors and are characterized by differential expression of several hundred genes. Strict compartmentalization of key C 4 enzymes either to mesophyll (M) or bundle sheath cells is considered a crucial step towards the evolution of C 4 photosynthesis. In this study, we demonstrate that the 50-flanking sequences of the C 4 type phosphoenolpyruvate carboxylase (Ppc) gene from three C 4 grass species could drive M-cell-specific expression of a reporter gene in rice. In addition to that, we identified about 450 bp (upstream of their transcription start site) of the analyzed C 4 Ppc promoters contain all the essential regulatory elements for driving M-cell-specific expression in rice leaves. Importantly, four motifs of conserved nucleotide sequences (CNSs) were also determined, which are essential for the activity of the promoter. A putative interaction between the CNSs and an unknown upstream element (s) is required for driving M-cell-specific expression. This work identifies the evolutionary conservation of C4 Ppc regulatory mechanisms of multiple closely related C 4 grass species. | |||||||
