RNA Transcript Expression of C4 cycle enzymes from four selected species of the Nyctaginaceae.
| PEPC1 | PEPC2 | PEPC3 | NAD1 | NAD2 | NAD3 | NADP1 | NADP2 | NADP3 | |
| Mirabilis jalapa (C3) | 164 | 19 | 105 | 50 | 28 | 4 | 122 | 4 | 75 |
| Allionia incarnata (C4) | 12069 | 33 | 88 | 80 | 25 | 2001 | 1751 | 114 | 13 |
| Boerhavia burburgiana (C4) | 17742 | 1 | 144 | 56 | 6 | 0.4 | 8563 | 2 | 144 |
| Boerhavia coccinea (C4) | 9331 | 0.1 | 128 | 85 | 27 | 0.2 | 3562 | 2 | 121 |
Yellow shading indicates the expression values of gene copies that are predominant in the C4 metabolic cycle. Green shading indicates enhanced expression of genes for which the activity in vitro was negligible. PEPC, PEP carboxylase; NADP, NADP malic enzyme; NAD, NAD-malic enzyme. Data were generated from transcriptomes in the 1KP database (www.onekp.com) and are available in the NCBI Short Read Archive (Supplementary Table 4). PEP carboxykinase transcript levels were found to be negligible in each species.
