Effect of metyrapone on cytokinin nucleotide content in transgenic Arabidopsis plants when expression of the ipt gene has been induced for 12 h and deuterium labeling of ZMP in induced transgenic plants incubated on D2O-enriched media for 12 h
| Compound | Control | Metyrapone | t test | |
|---|---|---|---|---|
| Cytokinin content, ng⋅g−1 fresh weight | ZMP | 2,200 (61) | 729 (179) | P < 0.01 |
| iPMP | 67 (4) | 42 (2) | P < 0.01 | |
| Deuterium labeling, tracer/tracee ratio | ZMP | 4.5 (0.4) | 2.83 (0.8) | P < 0.05 |
