Assays

The reporter fusion constructs expressing clock proteins fused to NanoLUC or firefly FLUC were transformed into the cognate, clock-mutant host plants. Each host also contained a transcriptional FLUC fusion that was used to score the circadian period of each transgenic line in constant light. Transformants that expressed a functionally normal level of clock protein were selected by choosing lines that complemented the mutant's period defect back close to the wild type period. Note that the reporters ...
