Two phosphoenolpyruvate carboxylase (PEPC) genes with relative high transcript abundance in Kalanchoë fedtschenkoi. a Regulation of PEPC1 activity. b Diel expression profiles of PEPC1 (Kaladp0095s0055.1) and PEPC2 (Kaladp0048s0578.1) transcripts in K. fedtschenkoi, shown in the left and right Y-axis, respectively. OAA Oxaloacetate, PEP phosphoenolpyruvate, PEPC PEP carboxylase, PPCK PEPC kinase, PP2A protein phosphatase 2 A. White and black bars indicate daytime (12-h) and nighttime (12-h), respectively
